coral. Marine invertebrate of the class Anthozoa in the phylum Cnidaria. Has a skeleton of lime (calcium carbonate).
No. Cniderians are soft bodied, simple creatures like jellyfish, anemones and corals. Crabs are arthropods.
jellyfish is not listed as vertebrates because it is a hollow bodied-animals and one of the simplest invertebrates.
Cnidarians: sea anemones, coral and jellyfish,SpongesAnnelids: Segmented flatworms,Ediacarans: An immobile pan cake shaped or fern shaped organisms. Lived in the sea bed, they had no organs and a very simple body structureMicroscopic bacteriaAlgae, mosses, (soft bodied organisms)
Because leatherbacks primarily eat jellyfish. They have two sharply pointed cusps, one on the upper and one on the lower jaw that allows them to pierce jellies and other soft-bodied organisms.
Yes and other soft-bodied invertebrates that float in the water column.
Coral, jellyfish, and aneomes are hollow bodied animals
A anemone is a kind of flower in the sea. People thought a sea anemone looked a little bit like that flower, so theycalled it after the plant. They look like an upside-down jellyfish, with tentacles pointing up.
jellyfish have no bones, exoskeleton, or shell to protect or support them. The jellyfish is considered simple-bodied because, like its Cnidarian cousins, it has no head, brain, heart, eyes, or ears. Thus it is also lacking in the sensory systems that correspond to these organs.
Locomotion ... it acts as a lever system for the muscles to work on.
they tend to live in deeper areas of the ocean, and some, like coral polyops and sea anemones, either build their own homes or have a good defense.
Animals with no backbones are called invertebrates and they include insects, worms, spiders along with soft bodied animals such as sponges, sea anemones and jellyfish.Invertebrates are the animals without back bones.
No. The word mollusca refers to a soft bodied organism and all mollusks are soft bodied. But not all molluscks have 2 shells: for example, abalones.
