During night, the parrotfish surrounds itself with a transparent mucus. It serves as protection: repulsive against parasites but it also prevents predators to olfactory find it.
This concon takes between 30 minutes and one hour to build each night.
You have to be very careful about this mucus when diving at night. Putting your torch on the mucus can disrupt the fish. Following the destruction of the mucus and a state of stress, the parrot will return to find shelter and build his mucus again.
So be careful when diving at night please!
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 tiger shark has slender marks similars to the lines of tigers, hence its name.
When it is juvenile, these marks are round and not vertical. They change when it grows.
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.)
