I'm a biology Master's student with a Bachelor's degree in biology. I post about animals, alive and extinct, and the insane, often obscure things about them. If that interests you, feel free to follow.

I started trying to write up the compilation thread of social hunting in non-mammalian predators today. So I've been closely looking at every example I have on me, making sure I understand each publication's methods and results. Just the examples for fish ALONE are a lot.

More art by Alexis Rockman! This time a derelict, post-apocalyptic Bronx Zoo.
Please don't ask me about the elephant and the okapi, I have no answer for that

Got two job offers, comparable pay and benefits. One is literally in the CDP I live in, so I think I’m probably going to do that one, although I’m going to have to do weekends after my first week there. It’ll hurt declining a regular-ass Monday-Friday 😭

An adult female red deer is substantially more massive than any wolf. You’ve heard me say it a thousand times. If a single wolf can take prey this much larger than itself, then imagine—

There was an instance where Bornean white-bearded gibbons and maroon langurs worked together to mob a Sunda clouded leopard. An infant gibbon that was previously seen with the group was no longer present, leading to a possibility that it was preyed on by the clouded leopard.

Any time you guys look at speculative evolution that takes place in Earth's future, do you ever think about how ancient things from real life would be by then?

More Alexis Rockman art. This particular piece makes all the anachronistic animal art I've ever commissioned look tame.

Today I gave a public comment at the City Hall hearing focusing on the fossils from Port Kennedy Bone Cave. I can only hope now that shedding light on a specific example of the Academy’s 19 million specimens has solidified their plight to the council members.
