Build Me an Ark
"So never mind the darkness, we still can find a way,'Cause nothin' lasts forever, even cold November rain."
- Guns n Roses, November Rain
There's all sorts of natural disasters which a zookeeper has to cope with, some of which I've never had to deal with (at least a major one) - fire, earthquake - others I have - blizzard, severe storm, drought. Perhaps the natural disaster I've dealt with the most often, and which stresses me out the most, is flooding. Flooding poses the same risk of damage and loss of life - human and animal - as the others, of course. It also has a heightened risk of escape. Storms and earthquakes can also damage cages and allow animals to escape, it is true, but floods have an inconvenient ability to fill in moats and raise and overflow the water features of exhibits. What once was a barrier keeping the animal in its enclosure suddenly becomes a highway that leads the animal out of its enclosure.
I'm a pretty poor swimmer, and drowning has always been a possibility that scares me. That's something I think a lot about when I'm running around a zoo in shin-deep water. It's something I really think about when I find myself sharing water with an animal and I know that animal is definitely in its element whereas I am not. On dry land, even a fairly large alligator or crocodile is pretty easy to work around safely. When all of the dry land in its exhibit is now drowned beneath the rains, suddenly the odds aren't quite in your favor anymore, and it's amazing how little water it takes even a very large alligator to hide in. Leaving said alligator alone, unfortunately, was not an option for safety reasons during the flood.
In one of the most startling flood incidents I had, a sudden rainstorm flooded the (normally dry) moat of our capybara exhibit. I ran to check on them and couldn't see any of them in the habitat. Panicking, I hopped the fence and splashed into their moat, chest deep on me (not my better idea). The second I did, the capybaras all surfaced in the water all around me, bobbing to the surface just feet away. They seemed to be loving their pool. I wasn't loving the fact that the surface of the water was now level with the top of the moat. Had they been so inclined, they could have hopped right out of the moat, walked across the path, jumped into the nearby creek, and swam off into the distance.
That creek, however, was also a natural component of a few hoofstock exhibits, and in its swollen state those animals found themselves standing on vanishingly small islands in their now-flooded paddocks. After careful discussion, we decided to open the gates to the paddock and let the animals that couldn't be caught up and relocated just roam the zoo at large (the perimeter gates were closed) and move to higher ground. When the waters receded, we were able to use food to coax them back to their exhibit.
The more I look back on it, it seems like we actually had a lot of crazy floods at that zoo. Floods that the old timers there said had once been once a decade were now occurring two or three times a summer. I'm sure that there's no possible climate change implications in that, of course...

Species Fact Profile: Sarcastic Fringehead (Neoclinus blanchardi)
Sarcastic Fringehead
Neoclinus blanchardi (Girard, 1858)
- Up to 30 centimeters long, weigh about 300 gram. Slender build with large pectoral funs, small pelvic fins. Loose folds of skin on the face are fringes of the common name. Largest member of the blenny family
- Skin is largely scaleless. Body color varies from warm brown to gray with dark blotches. Blue eyespot on the dorsal fin
- Males can open their mouths extremely wide, revealing brightly colored interior (blue with yellow lining) with some fluorescence. When the mouth is open (expanding its apparent size four-fold), it serves to intimidate both rival fringeheads and potential predators
- Often found in crevices, with only their heads exposed (will readily take shelter inside man-made objects, such as bottles and cans). Females may select males based on the quality of their shelter. Very protective of shelters and will often fight over access - an unsheltered fringehead is very vulnerable to predators
- Feed by charging from their burrows and sucking down small prey - the large gape of the males is actually an impediment to effective feeding
- Largely ignored by fishermen due to small size and aggressive nature, will readily bite if handled (their common name refers to the original meaning of "sarcastic," from the Greek for "to tear flesh" - the mouth has several needle-sharp teeth)

Humor: Winter in the Zoo
Things have been a little grim and grumpy lately, so I thought folks might enjoy this old German cartoons that I found depicting winter in the zoo. Pardon the poor translations, Google translate did the best it could when I typed the captions in.
"As the Zoo Director's wife, you have to come to terms with the heating oil prices these days."
"It's too cold for him outside now, so he helps us punch the tickets inside."
"Paul once again makes shoveling snow easy for himself."
"Hello, Meteorological Institute? Snow depth at the moment is 1.6 meters."

All Creatures Great and Small
Animal welfare seldom makes the political mainstage, mostly because it's usually seen as a local issue, rather than a federal one. I have a hard time seeing it ever being a dominant political issue in the manner that immigration or abortion will. Still, it easy to see that these are issues that people feel very strongly about (sometimes violently so, judging from the amount of death threats that swirl around whenever these stories make the news), they shouldn't be swept aside as filler stories or light news. (Most) people care very much about the wellbeing of animals, and the question of how they should be treated are topics that are worthy of serious discussion, if only to help us as a society improve our collective empathy.

Book Review: Many Things Under a Rock - The Mysteries of Octopuses
A person wishing to know what it would be like to encounter extraterrestrial intelligence could do much worse that meet an octopus. The eight-legged cephalopods are among the most intelligent creatures on earth, and yet theirs is an intelligence so different from ours. Whenever I encounter an octopus, I'm struck by how they manage to be so similar and yet so different from us at the same time.
Biologist David Scheel had spent much of his earlier career studying mammals on the plains of East Africa, so transitioning to the study of the what is probably the world's most charismatic invertebrates in the icy waters of Alaska is quite a change. Scheel brought an informed outsider vantage point to his study of these creatures, providing a lot of interesting insights into the challenges and rewards of studying these often-cryptic animals. His resultant book, Many Things Under a Rock, takes its name from an indigenous Alaskan name for the giant Pacific octopus, the species that the book is primarily focused on.
As the title implies, there is a heavy indigenous influence to Scheel's book, which I very much enjoyed. I suppose I tended to think of most underwater creatures as existing almost on a separate plan of existence from humans, at least until people began venturing under the surface with SCUBA gear and what not (ignoring the fact that octopus can leave the water, something the vast majority of fish and other marine creatures can't do). The truth is that people have a millennia-long association with octopuses, both as sources of wonder and fear (Scheel has a chapter devoted to the cryptozoology of octopuses), but, more practically, as a source of food. Likewise, I suppose on some level I knew that octopuses were animals of the northern oceans, but I never had really thought of them as Alaskan wildlife before.
In this exploration of octopus behavior and anatomy - how social are they? how do they use tools? how do they reproduce? - Scheel spends much of this time diving among them in waters around the world. He also features captive octopuses in his work, and even maintains a small aquarium at his university to allow his students to have hands-on experience with the creatures. The Seattle Aquarium and Alaska SeaLife Center are also highlighted here. Sometimes Scheel's work even comes home with him, and he describes an octopus that takes up residence in the fish tank in his living room. These stories are particularly enjoyable, because, with more prolonged, regular encounters with the same animals, we really get to see their personalities - from affectionate to mischievous - shine through.
Octopuses are easily among the most popular of aquarium animals, and their eight-legged grip on pop culture and science have been evident for many years. At a superficial level, it seems like many folks just think of them as scary sea monsters. It's easy to see how they could be considered frightening, being so eerily different from us, and yet so recognizable. Beyond that first impression, however, there is a creature that is so remarkably intelligent, sensitive, and charismatic as to install enchant any human lucky enough to have met them.

An Aardvark Interlude
A lot of people are still sad and upset over the events of this week, and I'm certainly not saying it's without reason. Fortunately, zoos and aquariums are a goldmine of cute animals which not only help brighten our moods after misfortunes, but also remind us that there's plenty of good in the world worth fighting over. Consider this aadorable aardvark recently born at the San Diego Zoo Safari Park:

Political Animals
My boss's house loomed over the private zoo where I worked like a feudal manor overlooking its serfs... which, I suppose, was not an inaccurate way of looking at it. Even though it was just yards away from the keeper office, and though I was one of the senior members of the staff, I only stepped foot inside the house once in the four years I worked for him. I found it to be an awkward, uncomfortable experience - everything seemed a little wrong to me, a little stark, and a little... I don't know... gauche? More emphasis on expensive than aesthetics or comfort. I also was bothered by the fact that, though the living room walls were lined with expensive looking shelves, it took me a while before I finally saw a book.
I was not the least bit surprised to see that, instead of an animal tome, it was the recently-released memoir of Sarah Palin.
No community (especially one as unruly and - often - poorly socialized as ours) is ever truly monolithic. Still, taken as a whole I've noticed that the zoo community tends to lean left of center. It's not surprising. Most of us start of in it as young, well-educated, and with a deep interest in conservation and environmental issues. Animal care requires a degree of empathy, which often extends to humans as well as creatures, and most zoos are located in cities, which tend to foster more progressive viewpoints. Oh, and most of us are also perpetually broke. Even those of us who climb the ranks tend to remember where we came from and continue to empathize. Not that I haven't met politically and culturally conservative keepers, it's just not as common, and they tend to be part of the exception to the rule.
The anti-rule, if you will, the complete contrast, tend to be the owners of private facilities, such as my former boss. They all tend to be die-in-the-wool blood red. Part of it may be a greater concern about financial matters; owning their own zoos, they tend to be a fair bit less idealistic and more focused on the bottom line, which I can hardly fault them for. Part of it's probably cultural too, as such facilities are much more likely to spring up in rural areas. At the same time, I've also noticed an angry, anti-regulatory streak (and if you're in the zoo world, you realize just how many forms of regulations the field is subject to), a constant simmering anger about government agencies and inspectors who dare to tell them what to do with *their* animals.
Because these facilities are generally unaccredited and don't participate in the formal breeding programs, they have to buy their animals, or trade for them. I feel like sometimes the constant buying and selling of animals fosters a viewpoint of them as commodities in their eyes. I remember walking up on the owner and his wife as they were stroking a young camel I had been raising. I was so eager to hurry up to them and tell them about how he'd been doing, his training and his growth - until I got close enough to hear that they were wondering what price he'd fetch.
The disdain also extends to the keepers, who tend to be even less-well paid than their counterparts in public zoos, and have fewer opportunities. I remember my boss plopping down next to me on a bench one day and saying "Keepers are like tissues," he told me with no preamble "You use them. Then you get new ones." With that he smiled at me and wandered off.
I've been following the giraffe drama out of Natural Bridge - the stay on the removal of the remaining three animals has been lifted. A lot of the commentary from the zoo and its allies has been focused on the heaping abuse on the state, the courts, and government in general; a few folks have even claimed that they think Trump will swoop in and save them, though I doubt that it's made it across his portfolio at this time. Some of the posters just went on all Q-Anon crazy, and I'm glad I don't have to deal with them, either in real life or online.
It marvels me that people who are drawn to the same basic life decision - wanting to spend their careers working with animals and share them with the world - can produce people with such different outlooks on just about everything - including the animals themselves and how they should be managed and cared for.

Species Fact Profile: Oriental Fire-Bellied Toad (Bombina orientalis)
Oriental Fire-Bellied Toad
Bombina orientalis (Boulenger, 1890)
- Body length 3.5-8 centimeters long, weight 25-55 grams. Females are larger than males, but males have thicker forearms; during the mating season, males also develop nuptial pads on their first and second fingers.
- Dorsal color varies from brownish-gray to bright green, often with some dark spotting; dorsal skin has many pronounced tubercles,. Ventral surface is bright red or yellow (the "fire belly"), also with black spotting
- Unlike many frogs and toads, cannot extent their tongue to catch prey, so instead jump on it
- Skin contains a toxin, bombesin. While primarily relying on the camouflage of their dorsal surface to hide from predators, if they are seen they will flip over and arch their backs (position called unkenreflex) to show off their red bellies, warning predators' of their poison. Some species of snake can eat the toad with no ill effect. Toxin is generally not very harmful to humans, but can be introduced through mucus members after handling.
- Hibernate from late September through late April or early May, sometimes alone, sometimes in small groups. Hibernate inside fallen trees, stone piles, or in the leaf litter, but sometimes in water
- Commonly kept as a pet, as well as a research specimen, among the best-studied of amphibians
- Very resilient to habitat disturbance, and can even be found breeding in heavily polluted water. Despite this, and their popularity as pets, they have not become invasive

Cheyenne Mountain Speaks Out
For as long as we have zoos and aquariums, there are guaranteed to be folks who are determined to oppose these institutions on philosophical grounds. When that happens, the question always becomes, how best to respond? Ignore it, try not to give any oxygen to the complainers, hope they just fade away? That can just give cede the entire philosophical floor to them to make their claims unchallenged. Fight back? There's the risk of looking too defensive, or like you have something to hide or be ashamed of.
It's a tough call. I've seen different zoos try each strategy, with the result sometimes varying. SeaWorld was slow to respond to criticism about its orca program, which only allowed that backlash to snowball.
Recently, Cheyenne Mountain Zoo in Colorado Springs, CO, went with option #2. In response to repeated attempts by the Nonhuman Rights Project (NhRP) to have the zoo's African elephants declared persons and "freed" for the zoo, CMZ had had enough. Their statement to their followers, below. It's a bit of a read, but I'm glad to see a zoo put out a detailed, well-thought out and well-reasoned response to set the record straight and stand by their animal care practices.
