Younger this trevallow is, more the filaments present on its fins appear large compared to its body. This allows it to look like a jellyfish when it is juvenile and therefore to have fewer predators.
This trevallie often moves in shoals.
Mammals have a horizontal tail.
Fishes have a vertical fin.
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.
