biscuit sea stars

Marine scientists have undertaken the difficult task of replacing the beloved starfish’s common name with sea star because,  the starfish is not a fish. It’s an echinoderm, closely related to sea urchins and sand dollars. Starfish is the common name for a group of animals called sea stars. Sea stars are actually part of the phylum echinoderm and are related to sea urchins, brittle stars and sea cucumbers – they are not fish at all! Sea stars play an important role in deep-sea ecosystems, especially as predators of sponges and corals.

seastar biscuit

There are some 2,000 species of sea star living in all the world’s oceans, from tropical habitats to the cold seafloor.  Biscuit Sea Stars are usually middle-sized sea stars with a characteristic double range of marginal plates bordering the disk and arms. Most of them have five arms, often short and triangular, around a broad central disc. Many species are pentagonal or subpentagonal, covered densely with granular, seed-like protuberances, hence the name of the family "seed-star" (gonium+aster). This distinctive bright orange-red sea star is called the Biscuit Sea Star because it is about the size of a large biscuit. biscuit sea starThe upper surface of the Biscuit Sea Star is covered with many interlocking small plates and six to eight larger plates along the edge of each of their short arms.The Biscuit Sea Star lives on intertidal rocky shores and in coastal waters to a depth of 40 m, feed on sea squirts, sponges, bryzoans and algae.

Did you know that the male cardinal fish, King of mullets , protects his eggs via carrying them in his mouth until they are hatched and release in the water..? It is not an easy job..Like the octopus mother that period he is vulnerable and unable to feed, because his mouth is a safe shelter for 20,000 eggs. What an indearing father!


cardinal fish

One fine day at the reef lady C was courting using all her charm possible and the male cardinal fish fell for it. She releases the eggs and he takes all of them to the last into the safety of his mouth.For about 20 days he will seclude himself to safer areas ,forgo eating ,and breath around a mouth full of living marbles. But he will never give up his babies ,oh no. When the eggs will hatch he will let them shelter in his mouth for an additional 6-10 days ,until they are ready to stand for their survival.

Spiny Lobster

Most animals eventually get old and die. But a few lucky species don't seem to feel the weight of time, and just keep going and going! Spiny lobsters are biologically immortal. They do die, but they don't seem to age. They can be killed by a predator, a disease, or a catastrophic change in the environment. But unlike humans, they rarely die simply because they get old.

 Lobsters, when they die, seem to die from external causes. They get fished by humans, eaten by seals, wasted by parasites, but they don't seem to die from within. Of course, no one really knows how the average lobster dies. There are no definitive studies.
