Because brittle stars are very fragile. Interestingly, Brittle stars use this fragility to defend themselves by easily losing arm segments or even entire arms. This strategy works because they are also able to regenerate these lost parts. They use their brittle quality and regenerative powers, in a way similar to that of some lizards, who lose part of their tails to confuse, appease, and evade predators.Brittle stars, Ophiuroids, are echinoderms, closely related to basket stars and distantly to star fish, sand dollars, and urchins.
Pluto
are brittle stars decomposers
It turns your toenail dark (sometimes light) yellow, it smells bad and can make your toenail very brittle.
True. Metalloids look like metals but are brittle and are not good conductors.
Brittle stars crawl and basket stars do not move or crawl.
yes,brittle stars are cold blooded.
They are preyed upon by shells (like the Triton shell), some fish (like the trigger fish), crabs and shrimps and by other echinoderms like starfish which are carnivorous. From another source: Creatures that snack on brittle stars include fish, crabs, hermit crabs, mantis shrimp and even sea stars and other brittle stars.
They like to live under rocks on the sea floor.
Some brittle stars breed asexually. Most brittle stars are either male or female however some species are hermaphroditic.
Some predators of the Brittle Star are: fish, crabs, hermit crabs, mantis shrimp, sea stars and other brittle stars. Brittle stars can regenerate limbs that are broken by predators.
No they do not. The respire like sea stars and other echinoderms. Lungs only ever breath air.
Yes - just like other members of the Phylum Echinoderms, brittle stars are host organisms that benefit from symbiosis. They are hosts to many organisms including shrimps, crabs, worms, and snails. Research also indicates that there are symbiotic relationships between species of brittle stars - these relationships are especially important during the early stages of life. If you have access to this online journal, take a look...it explains symbiosis among species of brittle stars in more depth: http://www3.interscience.wiley.com/journal/118505905/abstract?CRETRY=1&SRETRY=0
no
With there arms.

if you are moving then the stars may look like their moving but their not but shooting stars move
