These birds from New Zealand are friendly but not great at staying safe from predators.
They mostly eat bamboo, which isn't very nutritious.
They move slowly to save energy because they don't eat much.
They couldn't handle people hunting them and went extinct.
These ants wander around aimlessly, sometimes in circles.
They've been seen staring at the sky during storms, which can be dangerous.
They like to stick together in groups, even if it's not safe.
They put their heads in the sand when scared, but it's not because they're dumb.
They show off their bright rings when scared, which isn't smart.
They're good swimmers but sometimes try to mate with strange things.
