Is a sea anemone a porifera?

The main features to recognize members of Porifera (sponges) and Cnidaria (corals, sea anemones, jellyfish) are presented.

Is sea anemone an echinoderm?

They are echinoderms like starfish, sea anemones and sea cucumbers but are different from sea anemones, which are small marine animals with a tubular body and circles of tentacles.

Which groups do sea anemones coral and jellyfish belong?

Corals, sea anemones and jellyfish all belong to the same large group of animals – cnidarians. The name comes from the Greek 'knide', meaning nettle – they carry a sharp sting in their tentacles.

Is anemone a sponge?

Anemones are not a type of Soft Coral

Anemones are also more closely related to coral and jellyfish than they are to sponges. Anemones are cniderians like jellyfish. They are all fleshy and can sting.

Which feature do porifera Cnidaria and platyhelminthes share?

Key Concept. Porifera (sponges) have specialized cells and an endoskeleton but lack true tissues and body symmetry. Cnidaria (jellyfish and corals) have tissue-level organization and radial symmetry. Platyhelminthes (flatworms) have a mesoderm cell layer, simple organ systems, cephalization, and bilateral symmetry.

Which one of the following is an echinoderm?

Sea lily. Hint: Echinoderm is a member of the genus Echinodermata of marine animals. Adults are recognized by their radial symmetry (usually five points) and include starfish, sea urchins, sand dollars and sea cucumbers, as well as water lilies or “stone lilies”.

What makes an echinoderm an echinoderm?

An echinoderm is an organism (all marine) that has a spiny skin. ... Most echinoderms have pentamerous radial symmetry, meaning they can be divided externally into five equal parts along a central oral/aboral axis. Echinoderms also have a water vascular system.

Are sea anemones segmented?

Taxonomic level: phylum Cnidaria; grade of construction: two tissue layers; symmetry: radial; type of gut: blind gut; type of body cavity other than gut: none; segmentation: none; circulatory system: none; nervous system: network of nerve cells; excretion: diffusion from cell surface.

What are the three classes of cnidarians?

Cnidarians are divided into three major classes. These are the Hydrozoa (hydras and other colony-forming species), the Scyphozoa (jellyfish), and the Anthozoa (sea anemones and corals).

How do corals differ from sea anemones?

Corals. Corals are different from anemone because they have a skeleton of sorts. Anemones are squishy and basically filled with water. Corals create a hard skeleton of calcium carbonate.

Are sea anemones and sponges related?

Sponges are members of the Phylum Porifera, which means "pore bearer." They make a living by pumping seawater through the many pores in their bodies and filtering out the particles, which they then eat. ... Sea anemones belong to the Phylum Cnidaria. The cnidarians (anemones, corals, jellies, etc.)

Is coral a sea anemone?

Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and Hydra. ... Some species of sea anemone live in association with hermit crabs, small fish or other animals to their mutual benefit.

What class is cnidarians in?

The phylum Cnidaria is made up of four classes: Hydrozoa (hydrozoans); Scyphozoa (scyphozoans); Anthozoa (anthozoans); and Cubozoa (cubozoans).

What do cnidarians and Platyhelminthes have in common?

Like the cnidarians, flatworms have a digestive system with only a single opening into the digestive cavity, but in independently living marine flatworms the cavity branches into all parts of the body (Fig. 3.37 B).

How are Platyhelminthes different from cnidarians?

Cnidarians are diploblastic, whereas Platyhelminthes are triploblastic. Platyhelminthes possess bilaterally symmetrical, soft, worm-like elongated bodies, whereas cnidarian possess radially symmetrical, soft, medusa-like or polyp-like body forms. ... Cnidarians have cnidocytes, unlike the Platyhelminthes.
