The gray shark is often gregarious during the day and therefore visible in broad banks. It is more lonely during the night.
It is a curious shark, who does not hesitate to approach the divers and get away just after.
The gray shark must swim continuously to feed these gills with oxygen. He is therefore fond of the passes that allow him through the strong current to eat oxygen without effort.
Some sharks can stay motionless on the sand (white tips reef sharks, nurse sharks, etc.).
These sharks don't have to swim to bring oxygen to their gills like other sharks (grey, hammerheads tc.)
Parrotfish create a protective envelope around them when they are sleeping.
So, don't put the light on them during night dive to don't to wake them up and break this envelope.
The whale shark is the largest fish in the world!
Some whales are larger, but they are mammals, not fish!
