I'm going to be talking about the the In this strange universe, the sea cucumber, also called Holothuria, is in the right place. It is a valuable ally of the Neptune grass. The anatomy of the Holothuria is a digestive tube with an opening at each end, an inlet and an outlet. The Holothuria spends its time absorbing sediments and waste from the seabed. It filters and regenerates them, thus enabling the Neptune grass to grow better. It moves only a few meters per day, but swallows about 45 kilos of food per year. The animal is not particularly attractive, but very useful. In the Neptune grass there is another small fish, which is also specialized in cleaning. The Holothuria has a mission. It frees the fish in the sea grass from parasites. To show his intentions, he swims in a special way. The customer also takes a peaceful stance. Other animal colonies grow in a similar way as corals, the gorgonias. They are masters in construction. Their structures can be over one meter high.

Mimosa nemons live in light-protected colonies and can cover several square meters of rock. They stay in areas that are permeated by currents, which bring them food particles within range of their tentacles.

The sea star moves on hundreds of small, elastic feet, which are located under its five large arms. It looks as if it were lying down, but in reality it is standing. The sea lions live in harems with several females and a single male. However, when the male disappears, a strange phenomenon occurs. The dominant female males and turns into a male within a few days, which takes its place. The sea lion is a transsexual. The male takes care of the nest, like the sea lion. It sets up a spawning ground on the algae-covered rocks. Sometimes it brings materials, like a bird builds its nest. It flutters over its construction to attract and seduce females, so that they lay their eggs there. Then it fertilizes the eggs and guards the nest. Thank you for watching!
