The anus if a starfish would be located on what surface?
Where is the anus in relation to the stomach of a starfish?
Where is the starfishes eyes located?
The eyes of a sea star (starfish) are located on the end of each arm. It is a very simple eye that looks like a red spot and can sense light and dark, but doesn't see much detail.
No, the male and female release their gametes into the environment where they will meet oppositely sexed gametes. Although some species brood their eggs (sit on them) and one species i know of Leptasterias tenera broods the eggs in its pyloric stomach.
Starfish do not tend to do either. They just travel in the area they are born and eat the food offered.
What is the function of a pedicellariae on a star fish?
Pedicellariae protect sea urchins by snapping open if something touches its outer surface. If it is touched on its inner surface then it snaps shut. They can be toxic because some have poison glands inside of them. They are attached to the stalks at the base of the spines that cover the sea urchin.
The armour of a starfish feels very rough but once you have the starfish on your hand there are little tentacle with suction cups on the end that will stick on your hand and it will tickle a little bit.
On what surface is the Ambulcaral groove visible on a star fish?
Echinoderms can have ambulacral parts that include ossicles, plates, spines, and suckers. For example, sea stars or "star fish" have an ambulacral groove on their oral side (underside). This ambulacral groove extends from the mouth to the end of each ray or arm. Each groove of each arm in turn has four rows of hollow tube feet that can be extended or withdrawn. Opposite the ambulacral groove is an ambulacral ridge on the aboral side of each ray.

i think they have babies when they are old enough and find a you know like that............and after that they have babies in the sea and they maybe born them in their house on a cave or out on the shore i guess..........
No. A starfish is actually classified as an Echnioderm.
Average lifespan of a Starfish in the wild is up to 35 years
How do sea stars prevent desiccation?
Not at all well. To be taken out of the water is pretty much a death sentence for a starfish.
starfish poop the same way that they eat, and that is by making their stomach go inside out.
What are 7 levels of classifications of a starfish?
Starfish belong to the Animalia Kingdom, the Echinodermata Phylum, Asterozoa Sub-phylum, and Asteroidea Class. The seven orders of starfish are Brisingida, Forcipulatida, Notomyotida, Paxillosida, Spinulosida. Valvatida, and Velatida.
What are female starfish called?
I have never heard of any special names for male and female seastars (we who
study invertebrates don't like to call these animals "starfish"
because they're definitely not fish!). I think that people never came up
with names for male and female seastars because it's almost impossible to
determine the sex of a seastar without dissecting it. The only way to tell
from the outside if a seastar is a male or female is to catch it spawning --
if it sheds eggs, it's a female; if it sheds sperm, it's a male. Seastars,
and all the other echinoderms, lack any external features that identify them
as male or female. In other words, they are not sexually dimorphic. That's
just a fancy way of saying that males and females look the same.
I hope this answers your question. Good luck with your research!

yes they only eat clams, dead crabs, dead fish, and oysters!!! They eat small live fish and mollusks added to the list above. The starfish has a stomach outside the body and is able to send it into the interior of the shell and consume the creature from the inside. See the related link for more information.
Can a starfish regrow a broken leg?
No, it won't. The only way starfish's can produce is sexually, they have separate sexes. Cutting off a sarfish's arm will only cause it to die later, it will not grow into a serpate starfish.
