Nurse shark
Nombres alternativos: Ginglymostoma cirratum
The nurse shark can be found along tropical and subtropical coastal waters. They like to stay on the bottom of the ocean and most of the time they are harmless to humans unless they are being bothered by divers.
Nurse sharks are nocturnal which means they tend to be active at night. What's interesting about this species is that they tend to sleep together in large groups and they have even been seen cuddling and snuggling.
