Starfish

starfish are cool and should have organ systems cause organ systems are also cool

The scientific name is Acanthaster planci.

Because it doesn't need a partner to produce the new starfish.

An asteroidian is a starfish, a member of the Asteroideafamily.

Brittle stars are scavengers and eat just about any kinds animal or fish they come across. They are capable of eating everything from crustaceans to jelly fish.

lives for 8 years in aquariums but the actual life span isnt known

That usually means they're dead.....

why did not a college student answer this because u are stupied put the shut to the up

In gay slang, the term "bear" refers to male individuals who possess physical attributes much like a bear, such as a heavy build, abundant body hair, and commonly facial hair.They are generally diurnal, but may be active during the night (nocturnal) or twilight (crepuscular), particularly around humans. Bears are aided by an excellent sense of smell, and despite their heavy build and awkward gait, they can run quickly and are adept climbers and swimmers. In autumn some bear species forage large amounts of fermented fruits which affects their behaviour. Bears like to hunt fish....

Starfish are not fish. Broadly speaking, starfish are opportunistic feeders. To increase their chances of fertilization, starfish may gather in groups. Bears also gather in groups to find mates.

The ampullae of Lorenzini are special sensing organs called electroreceptors, forming a network of jelly-filled canals. They are mostly discussed as being found in cartilaginous fishes (sharks, rays, and chimaeras); however, they are also reported to be found in Chondrostei such as Reedfish[1] and sturgeon.[2] Lungfish have also been reported to have them.[1] Teleosts have re-evolved a different type of electroreceptors.[2] They were first described by Stefano Lorenzini in 1678

They reproduce and take sides of their mates... when this happens they will grow and develope.

starfishes enemies are big fish,the big fish dont eat them but most the big fishes scare them away,and maybe so the crab eats starfish :D :P :) BYEEEE

A) Starfish aren't even fish.

B) If by cleaned you mean eaten, then yes! Okay, seriously; most starfish are much to predatory for that kind of behavior, but the few that aren't still are most definitely not cleaners!

Regular starfish are in the order Forcipulata.

tiger fish and shark

(but I'm not completely sure may sure you check !)

I'm not sure either but I heard that they are preyed upon by shells, some fish, crabs and shrimp, and some carnivorous sea stars. But I don't know if that's true or not.

Sharks, fish and manta rays are predators of the starfish. Larger starfish also prey on and attack smaller starfish.

Animals like starfish and some micro-organisms have the facility to regenerate body parts if they get destroyed. It is the same as if we homo sapiens lose an arm and we could grow it back sometime later.

I have one i got on the beach. The best thing to do is soak it in bleach or alcohol for a day than put it somewhere sunny (outside it will smell) where it can finish drying out. Wiegh down the legs so they won't curl up.

• Many coarse spines cover the upper surface that have pincers (those pincers help obtain food by paralyzing prey)
• They have an endoskeleton;bony-like plates of calcium that are bumpy or spiny
• Radial symmetry with five parts or multiples of fives (like starfish have radial symmetry and five tentacles (most of them do))
• A water-vascular system;a system of fluid-filled internal tubes that carry food or oxygen, removes wastes, and helps echinoderms move (tubes eventually connect to tube feet).
• Tube feet;very strong structures that allow them to move and obtain food (act like sticky suction cups)

It depends what you're comparing them to. Here's a list some of the parts of a starfish: radial canal ring canal stone canal stomach reproductive glands digestive glands water vasculatory system optic cushion tube feet madreporite

A starfish has five limbs and if one of those limbs (which can also called arms or legs) is lost it can regrow over time. A starfish that is halved can grow into two starfish.
