Molluscs and crustaceans
Algae and sponges
Biodiversity in the Valencian litoral
Its green leaves are long and smoothed, being able to measure up to one meter and a half.
The average of life of its is of approximately 30 years.
Its role in the ecosystem is the most important.
Many species find its nutrients and its mansion in the Posidonia.
One of the most interesting properties of this plant is that it is capable of multiplying the surface of the soil between 20 and 50 times.

The size of the colonies can change from a few centimeters up to almost a meter.
It has a pace of very slow growth.
The species grows on rocky substrates.
Colonial species of orange color.
It forms masses more or less rounded.
It appears in rocks, normally dark bottoms.
It manages to have 10-20 cm of height.
It lives in rock substrats, from the surface up to 75 m.
The color is green or green yellowish, but it can also be whitish.
Raised sponge, branched out, from 15 to 50 cm of height.
It lives in moderately illuminated places, between 15 and 100 m of depth.
It has a yellowish or orange color.
It manages to take a meter of high place as one of width.
They are of red color, though it is frequent to find copies of yellow.
It forms real forests and lives in rocky bottoms.
It lives in rocky bottoms or hard substrata and can appearin other organisms.
The polyps measure 10-15 mm of length and approximately 5 mm of diameter.
The color is intense yellow, sometimes with orange tones.
Porífero of color almost always light blue, enclosed in occasions up to colorless.
It lives in slightly deep waters, and in caves.
It appears in the funds of sand, where it needs of solid remains to be fixed.
Its length can come up to 100 cm and can manage to reach 200cm with the widespread arms and they can weight 10 Kg.
Its body has form of sack and has 8 tentacles.
In case of threat it can express a cloud of ink to confuse his predator.
This mollusk can manage to reach 65 cm, of which the mantle, without head or arms can take 35cm.
The body is smoothed
The cuttlefish has 10 arms, 8 short ones with two rows of cupping glasses and two long arms
Its measures between 10 and 90 cm of length.
Its color changes from dark grey up to white in the underside
It is very voracious and eats crustaceans, worms, fish and other marine animals.
HABITAT: Rocky bottoms and posidonias, from the surface up to 40 m.
DESCRIPTION: The color is silver.
BIOLOGY: There are hermaphrodite individuals. The reproduction takes place between April and June, and the babies already are recognized by the black spot. Often it is possible to observe close to the surface in intermediate waters.
Habitat: It lives in banks which members are kept very grouped and move of coordinated form.
Characteristics: The species is hermaphrodite and reproduces in spring and autumn. The young individuals are especially carnivorous, but the adults are herbivorous.
Habitat and information: It prefers rocky zones in proximity to sandy zones. He lives in submarine meadows.
It is possible to see him swimming between two waters near the coast.
They are omnivorous but they prefer crustaceans, worms and smaller fish. It is a hermaphrodite fish.
The Dorada is a fish that lives in deep waters.
Between the eyes it has a golden spot that is the one that gives his name.
It can manage to reach up to 70 cm of length.
In the first years of his life, they all are males and with the age they turn into females.
HABITAT: Rocky bottoms and meadows of posidonias from 1 to 150 m.
SIZE: It can reach 25 cm of length.
BIOLOGY: Hermaphrodite specie. It reproduces between June and July. The fadri eats mollusks and crustaceans.
Diet: He eats any type of food of animal origin.
Description: The dorsal surface of the body is of color tile and ventral is yellow.
He lives in soft and muddy funds, and can live in depths between 150 m and 1.500 m.
Generally it measures between 200-400 m .
The galley is a crustacean that gives itself in the zone of the Mediterranean, on the Valencian coast.
Its presence threatens the existence of the animal and vegetable autochthonous species, for example the oceanic Posidonia.
The scientists say that it is not possible to eradicate and think that the situation is "worrying".
Caulerpa racemosa is an algae of tropical origin. During the last decade it has expanded along the Mediterranean western coast colonizing the habitats of the posidonia.
Caulerpa taxifolia is a tropical toxic alga, which is putting in serious danger to the Mediterranean ecosystem.
The Caulerpa taxifolia comes from tropical seas.
One of the most dangerous algae.
It drowns under of the Poseidonia, which realices a fundamental paper for the ecosystem.
