Other brittle stars are carnivores that use their arms to sweep tiny creatures to their mouths. Yet others are scavengers, nibbling on their food with their jaws or using the tube feet near their mouth.
What type of eaters are brittle stars?

What is a brittle star classified as?
brittle star, also called serpent star, any of the 2,100 living species of marine invertebrates constituting the subclass Ophiuroidea (phylum Echinodermata). Their long, thin arms—usually five and often forked and spiny—are distinctly set off from the small disk-shaped body.
Is a brittle star Decomposer?
An ocean food web incorporates many different organisms in an ecosystem, from primary producers to consumers like fish, fishermen, and whales, as well as decomposers like brittle stars and bacteria.
Why are brittle stars called brittle?
Brittle stars are named for the ease with which their arms break off when touched; these animals, known collectively as ophioroids, are also called serpent stars (ophis means snake in Greek) because their long arms resemble serpents.
What are the characteristics of a brittle star?
Characteristics of brittle stars
Characterized by radial symmetry with a central body from which five snakelike arms protrude. The arms are highly flexible. There is no replication of internal organs, just one set in the central disk. Compared to starfish, brittle stars have a much smaller central disc and no anus.
Will brittle stars eat fish?
Temperament / Behavior : These brittle stars are scavengers that should feed on detritus, dead organisms, etc. They should leave corals and fish alone. ... These are known fish eaters.
Are brittle stars edible?
Brittle stars are not used as food, though they are not toxic, because of their strong skeleton.
Do brittle stars eat shrimp?
Some are active carnivores and will pull down unfortunate shrimp or even small squid if they stray too near (see The Echinoblog ). It is quite amazing to see them feeding in an aquarium. ... Apart from eating, the brittle-stars main concern is not being eaten.
Is a brittle star single or multicellular?
That is, they are able to exist in both a unicellular and multicellular form, depending on environmental conditions, such as nutrient availability or fluctuations in temperature, growing as a mold, for example, at 25 °C (77 °F), and as yeast cells at 37 °C (98.6 °F).
Do echinoidea have arms?
Sea urchins and sand dollars are examples of Echinoidea. These echinoderms do not have arms, but are hemispherical or flattened with five rows of tube feet that help them in slow movement; tube feet are extruded through pores of a continuous internal shell called a test.
Are starfish decomposers?
Other sea creatures classified as decomposers include crustaceans and mollusks, bacteria, fungi, sea cucumbers, starfish, sea urchins, and other kinds of marine worms. ... Without decomposers like the Christmas tree worm, organic matter would just pile up and the nutrients in it would go to waste.
Are sea urchins decomposers?
Ocean decomposers have a variety of methods for gathering dead material to feed on. Echinoderms like sea urchins, sea stars and sea cucumbers hunt and eat live food, but they also move around and consume decaying organic matter that covers rocks and other surfaces.
Is a sea cucumber an animal?
Sea cucumbers are animals, not vegetables.
Found only in salt water, more than a thousand species of sea cucumbers exist around the world. These squishy invertebrates are echinoderms, making them distant relatives to starfish and urchins. ... Sea cucumbers are enjoyed as meals for other critters such as fish and crabs.
