Cnidarians

it is an Octopus or Squid.

Asexual and sexual reproduction, two methods of reproduction among animals, produce.

The comb jellies and the cnidarians, Shellfish regularly consume poisonous red tide organisms.

in a tank or in a coral reef

Scyphozoa-Cannonball Jellyfish

Anthozoa-Tube Anemone

Hydrozoa-Portuguese Man of War

Cubozoa-Box Jellyfish

Yes. Yes the do. Well, sponges anyway

Cnidocytes are the specific cells present in all cnidarians.Name of phylum Cnidaria is derived from the word cnidocyts which are stinging cells.These cells are most important cells for these animals because they are related with offence , defence and feeding.A cnidocyte consists of a capsule with a coiled filament barbs , a cnidocil , and a lid. It is discharged when cnidocil is touched.These cells are of 30 different types also used for attachment etc.

Annelids have endoskeletons

Hydra is a simple multicellular organism,so,it throws out solid waste matter through their mouth.

fish, shrimp,isopods, amphipods, plankton

The body systems that cnidarians have take two forms. The main body forms are medusa and polyp. Cnidarians do not have a transport system and the body surface is used for gaseous exchange.

Sea anemones are consumers yes.

Although most of the animal phyla are included in the deuterostomes and protostomes, cnidaria, porifera, placozoa and ctenophora are not included in the group of animals know as Bilateria (which contains the deuterostomes and protostomes). Cnidarians and ctenophores are in a group called Radiata, and Porifera and Placozoa are in the group known as Parazoa.

It is impossible to tell what year a Hydra-Mac skid steer with the serial number 62773 is through known public records. You can try contacting the manufacturer for specifics or a manual.

yes it is a coelenterata...

Type your answer here... the odyssey- the greek myth with the hero odysseus. The story was written by a greek poet Homer

Research is being done to determine how the venom of jellyfish can be used to treat cardiac problems.

Cnidarians are actually carnivorous fauna. Cnidarians are either polyps, such as sea anemones or coral, or free-floating medusae, such as jellyfish.
Polyps have a tube-like body with an opening on top that is surrounded by outward- and upward-facing tentacles.
Medusae are usually bell-shaped animals with a concave oral surface, or mouth, and tentacles that dangle downward from the rim of an umbrella-like body.

Four classes make up the phylum Cnidaria:
Anthozoa, which includes sea anemones and coral
Cubozoa, which includes Portuguese man-of-war
Hydrozoa, which includes jellyfish
Scyphozoa, which includes box jellies

Cnidarians live in aquatic environments and inhabit all depths, from the sandy substrate up to the surface. Some are even found in freshwater.
Cnidarian bodies have only one opening that serves as both mouth and anus. Food enters through the mouth and excess food and waste leave through the mouth as well.
Cnidarians have no need for a brain or a heart; instead, these animals have specialized tissues to coordinate basic bodily functions. A decentralized net of nerves and receptors allows the animals to negotiate their environment, whether they are moving about, detecting danger, or making a meal of any prey that swims by.

Unfortunatly, i don't think there are any official studies on hydras. i wouldn't know. all i know is that if you cut their heads off, they only come back doubled.

No. Humans are chordates.

Hydra is in the phylum of the cnidarians which is a radical symmetry. so ectoderm, the outer layr which form the nerve sytem. Also, the endoderm, the inner layer are presented in the hydra.

a hydra as a polyp is not sessile but when it grows to be a hydra it is sessile
