What biodiversity is found IN A BIOHUT®?

HERMIT CRAB

Pagurus anachoretus

This shaggy-looking soft bodied creature with olive green eyes protects itself by crawling into the empty shells it finds in shallow water.
Some live in symbiosis with anemones, whose sting acts as an effective shield against predators.

SHEEPHEAD BREAM

Diplodus puntazzo

If you put your head under the water, the first fish you will see are the sea bream!
They are very popular with fishermen and divers - both underwater and on the plate.
This one is a large fish that as an adult is solitary and can be recognized by its pointed nose.

BIG CLAW SNAPPING SHRIMP

Alpheus macrocheles

This orange shrimp, quite common in the Mediterranean, is characterised by its large claw that snaps to produce a powerful jet of water. The sound it makes allows other animals to identify it. It is used for defence, moving materials and feeding.

DUSKY GROUPER

Epinephalus marginatus

An iconic protected fish, it makes its home on a rocky seabed inside a shelter and does not move far from safety.
A voracious carnivore despite its rather sluggish appearance, it can grow to 1.5 m, weigh 100 kg and change sex once in its lifetime, going from female to male.

GREY DORADO

Spondyliosoma cantharus

This little-known fish is a real champion in changing its livery (colour). When young, it is an old gold colour. As it grows, it takes on a more silvery colour, but as night falls, it covers itself with 5 vertical stripes as if it were putting on its pyjamas.
