Relax,sit down for a couple of hours, and get this thing done. No TV, phone, iPod, or anything else. Just get this done.

Answer 2

Wow is this a coinsedence. My brother had to do a priject on that a few years ago. He got an A because he made 2 or 3 models our of clay and leabeled all of their parts. I think he did it in the last 3 days. I don't remember too muich but heres what I remember about the project.

-a Bat Star is approximately 10 cm across and it has webbing between arms

-It has various colours like: solid red, yellow, brown, purple, green

-they scavengeon a variety of plants and animals. it doesnt care if its dead or alive

-its relatives are sea cucumbers, sea urchins, and sand dollars

-They actually help clean the ocean because they are scavengers. They help clean dead animals and algae from the seafloor

Sorry all I got on that. Heres something else I found on the internet:

When two bat stars bump into each other, a gentle brawl begins. They seem to be “arm wrestling” in a slow motion skirmish. Each sea star tries to get its arm on top of the other’s arm. A winner isn’t apparent, and perhaps to the bat stars, the brawl isn’t gentle!

Bat stars reproduce by spawning. The male broadcasts sperm and the female broadcasts eggs from pores near the bases of their arms. Fertilization takes place in the sea, and currents carry the young to new homes.

Annelid worms (Ophiodromus pugettensis) live in the arm (ambulacral) grooves on a bat star’s mouth (oral) side. Here the worms have a plentiful supply of leftover food bits. As many as 20 worms may live on one bat star, but they don’t harm the bat star—this is known as commensal symbiosis.

Sea stars have external hard parts (exoskeletons) made up of little plates (calcified ossicles) joined by connective tissue. The bat star’s ossicles are so large and defined that they look like rough shingles. These shingles act like armor and protect the bat star’s vital organs.

From Wikipedia, the free encyclopedia
Jump to: navigation, search
Invertebrate is a term that describes any animal without a spinal column. The group includes 97% of all animal species — all animals except those in the Chordate subphylum Vertebrata (fish, reptiles, amphibians, birds and mammals).

Carolus Linnaeus' Systema Naturae divided these animals into only two groups, the Insecta and the Vermes. Jean-Baptiste Lamarck, who was appointed to the position of "Curator of Insecta and Vermes" at the Muséum National d'Histoire Naturelle in 1793, both coined the term "invertebrate" to describe such and divided the original two groups into ten, by splitting off Arachnida and Crustacea from the Linnean Insecta, and Mollusca, Annelida, Cirripedia, Radiata, Coelenterata and Infusoria from the Linnean Vermes. They are now classified into over 30 phyla, from simple organisms such as sponges and flatworms to complex animals such as arthropods and molluscs.

Since invertebrates include all animals except a certain group, invertebrates form a paraphyletic group. (For a full list of animals considered to be invertebrates, see animal.) All the listed phyla are invertebrates along with two of the three subphyla in Phylum Chordata: Urochordata and Cephalochordata. These two, plus all the other known invertebrates, have only one cluster of Hox genes, while the vertebrates have duplicated their original cluster more than once.

Answer 4

Bat star . but you didnt hear anything from me.
Description:
Size: to 10 cm across
Color: varies with each individual; bat stars may
be a solid color or mottled, orange, brown,
red, green, purple or pink.
The Bat Star is also called the “Webbed Star” as it has
webbing between each ray.
Habitat: found among rocks in low intertidal and sub
intertidal zones
Range: Sitka, Alaska to San Diego, with small
numbers of the species found in Mexico.
Diet: The mouth of the bat star is located on its
underside, and it actually extends its stomach out of its
mouth and digests its food externally. Its favorite foods
include other sea stars, tunicate worms and algae.
Predators: sunflower sea stars, crabs, fish and man.
Notes: Bat Stars don’t always have 5 rays—they can
have anywhere from 4-8 ray

Answer 5

Bat stars come in a wide variety of solid and mottled colors, including red, orange, yellow, brown, green and purple. They have webbing between their short, triangular arms, which gives them a batlike look. Normally, bat stars have five arms, but they occasionally have as many as nine arms.

Gill-like structures on a sea star’s back, which aid with breathing, give its skin a fuzzy appearance. Most sea stars have pincers (pedicellariae) that remove debris from the skin gills, but bat stars have no pincers and are free of debris. Perhaps small, beating hairs (cilia) cause a water current that keeps the skin surface clean.

Bat stars have sensors at the end of each arm that sense light and detect prey. When a bat star finds a food item, it extends its stomach over the prey and oozes its digestive juices onto it, liquefies the prey meal and then slurps up the resulting “soup.”



Diet scavenges on a variety of plants and animals, dead or alive

Size up to eight inches (20 cm) across

Range Sitka, Alaska to Baja California, intertidal to 951 feet (290 m)

Relatives sea cucumbers, sea urchins, sand dollars; Phylum: Echinodermata

Conservation Notes As scavengers, bat stars play an important role in the ecosystem, helping clean dead animals and algae from the seafloor. Fortunately, more and more people know that we all depend on healthy oceans, and that the survival of ocean animals, including bat stars, is up to us. Working together, we’ll discover better and better solutions to pollution, overfishing and other threats to the oceans.

Answer 6

Or you could do another invertebrate that is second cool. How did you find the name of the animal but no info about it?

Two links that will help you. The 2nd link provides a detailed description about the Bat Star!! Good luck

Answer 8

I don't have time to paste the information on http://en.wikipedia.org but look up Bat Star at http://en.wikipedia.org

Answer 9

Ask Jeff.

Answer 10

uhh invetebrate? i'm thinking a starfish?! there is tons of stuff on them.
