Fish 
It is strictly forbidden to use any kind of fishing tool especially underwater sparegun in combination with autonomus diving gear. In order to fish in Croatia it is necessary to have a fishing permit. Because of overfishing and endangered habitats some species of fish are protected especially sea horses which divers encounter the most.

Crabs
Crabs are endangered because of commercial overuse and destruction of their habitats. Hunting of some species (spiny lobster and european lobster) is permitted only for professional fisherman during the specific time of the year, while other species (spiny spider crab and mediterranean slipper lobstar) are protected.

Corals
Corals are sessile animals permanently attached to the surface where they live. They are endangered because of pollution, coastal construction, diving, accidental catch with fishing net and commercial overuse. Negligent divers very often damage coral colonies. Be careful and do not touch them.

Sponges
Sponges are diverse group of sessile animals of unusual colours and shapes. Most of them feed while filtrating the sea and some hunt small animals. Their habitats range from shallow to deep sea bottom but for divers they are very attractive in underwater caves. Sponges are endangered due to pollution, accindental catch and collecting. Although all species are endangered only four of them are protected.

Sea turtles
There are three species of sea turtles in the Adriatic sea, loggerhead sea turtle, leatherback sea turtle and green sea turtle. They come here very often and spend winter burying themselves in mud at the sea bottom but they do not come for breeding. These populations are critically endangered by accidental catch in the fising nets, long line fishing and pollution and are therefore strictly protected.

Sea mammals
All sea mammals, whales, dolphins and the Mediterranean Monk Seal are protected by Croatian lows. Only bottlenose dolphin lives permanently in the Adriatic sea. Other species of dolphins and whales only come occasionally.

Snails and bivalves
Having beautiful and attractive decorative shell some types of snails and bivavles are extremly endangered by illegal collecting and trading. Careless divers make a huge damage taking those as souvenirs. In the Adriatic some species are on the verge of extinction.
