Humpito
It can turn its stomach inside out and spit out unwanted contents.1
It can breathe while lying still on the bottom. It pumps water in through its first gill slit and out through the others, so it does not need to swim with its mouth open.1
Juveniles have individual personalities. Some are bolder than others when exploring new places, and they respond differently to stress.1
Juveniles can learn to link bubbles, lights or sounds with food, and they can learn by watching other sharks.1
Adults are often seen resting together in caves, but juveniles do not seem to be social.1
Each year it migrates south in summer and returns north to breed in winter.1
