Invertebrates

The one that we found in our yard is a Land Planarian. Here is a picture of the exact one we found. Perhaps this is your worm too? http://www.floridanature.org/species.asp?species=Bipalium_kewense

Sea Urchins spawn, much like fish, directly into the sea. First the male with release his sperm into the water and then the female will release her eggs. This type of mating is very common among water dwelling animals.

Marine scientists have undertaken the difficult task of replacing the beloved starfish's common name with sea star because, well, the starfish is not a fish. It's an echinoderm, closely related to sea urchins and sand dollars.

There are some 2,000 species of sea star living in all the world's oceans, from tropical habitats to the cold sea floor. The five-arm varieties are the most common, hence their name, but species with 10, 20, and even 40 arms exist.

They have bony, calcified skin, which protects them from most predators, and many wear striking colors that camouflage them or scare off potential attackers. Purely marine animals, there are no freshwater sea stars, and only a few live in brackish water.

Beyond their distinctive shape, sea stars are famous for their ability to regenerate limbs, and in some cases, entire bodies. They accomplish this by housing most or all of their vital organs in their arms. Some require the central body to be intact to regenerate, but a few species can grow an entirely new sea star just from a portion of a severed limb.

Most sea stars also have the remarkable ability to consume prey outside their bodies. Using tiny, suction-cupped tube feet, they pry open clams or oysters, and their sack-like cardiac stomach emerges from their mouth and oozes inside the shell. The stomach then envelops the prey to digest it, and finally withdraws back into the body.

The characteristics of cnidarians are that they have claws, hard exoskeleton, and reproduce sexually.

That answer is just silly. The phylum, cnidaria, includes hydras, jellyfish, sea anemones, and corals. Cnidarians are defined by the fact that they possess cnidocytes (cells that can either attach or sting) which are often used to grab and immobilize prey, as well as for defense and in rare cases, for locomotion.

Cnidarians are diblastic (two layers of cells), with a secreted layer between the inner and outer layer of cells, called the mesoglea. They possess a single gastrovacscular cavity that serves to respirate, disgest, and discharge waste. Commonly, tentacles surround the gastrovascular opening.

Cnidarians are predominately radially or bi-radially symmetric. The two common forms of cnidarians are a polyp form (attached, vase-shaped), and a medusa (bell shaped, free swimming) form. Some cnidarians are exclusively sessile (attached to a substrate), exclusively free swimming, or include both forms during their life cycle.

No it is a vertebrate. Fish have a backbone. Invertebrates do not have a backbone.

spider and slug

yes.

The armadillo, like all mammals, has an endoskeleton (inside structure of bone and cartilage) that supports the organs and muscles. The exterior scales of an armadillo are bone and horn, but do not constitute an exoskeleton.

Vertebrates are animals with a backbone (a.k.a a spine) we are vertebrates and so are the rest of the mammal kingdom.

Invertebrates are animals without a backbone like crustacean (Crabs) and Arachne and insects.

The rarest amphibian in the world is the golden toad. It is from Costa Rica. It was last seen in 1989.

They have no backbones. See related questions below for more detail.

the Road Runner is a type of bird and it is very small, contrary to the belief with loony toons the road runner is in face smaller than a coyote and isn't even a snack for one either lol. Hope it helps, Silver ^_^

dinosaurs are the animals which are warm blooded.

No because a crustacean has a exoskeleton and a mussel has a shell

I don't actually know the answers to it!! I just wanted to type something. Any way maybe like 10 or more years from now listen to like my songs and watch my sitcoms. So yeah. Kathy Morse out!!

Insects Rule!According to MSN's Encarta Encyclopedia,

"For sheer variety and abundance, insects rank among the most successful animals on Earth. About one million species of insects have been identified so far, which is about half of all the animals known to science."

Some scientists estimate that there are over two-hundred million insects for every human on the planet.

Being a vertebrate means having a vertebra - the Latin term for backbone. Vertebrates include fish, amphibians, reptiles, birds and mammals (including humans). Everything else in the animal kingdom is invertebrate, without bones. Many invertebrates have an exoskeleton of hard plates, like the armour of an insect, or the shell of a slug. Others are soft and naked like jellyfish.

So, if it has bones, it´s a vertebrate. ^^

It is vertebrate animal .

An organism that does not reproduce will eventually die out with the aging and death of its individuals. Many species reproduce rapidly and in large numbers to ensure the survival of enough adults to maintain the population.

There are an estimated 9,000 to 10,000 species of invertebrates on earth and that takes up 98% of all types of species on earth.

Sea urchins eat endlessly as long as there is food they are eating. They eat the algae growing in slat water tanks and the ocean.

none. some animals are chordates, but they are not in the superphylum vertebrata, which means that they are invertebrates

Invertebrate animals do not have a backbone or spine. Examples of some animals that are invertebrates are mollusks, worms, leeches, and echinoderms crustaceans, and arthropods.

conclusion animal kingdom
