Major Attributes:
- Tropical marine habitat.
- Mouth surrounded by tentacles with nematocysts.
- Partioned gastrovascular cavity.
- Secretes nonliving substance around outside of body to support and protect soft body tissues.
- Reproduces sexually by producing a free-swimming larva (planula) or asexually by budding or fission.
Which body form is not present in class Anthozoa?
The class Anthozoa includes all cnidarians that exhibit a polyp body plan only; in other words, there is no medusa stage within their life cycle. Examples include sea anemones, sea pens, and corals, with an estimated number of 6,100 described species.
What are the 3 subclasses of Anthozoa?
The class Anthozoa has three subclasses: (1) Hexacorallia (includes stony corals, sea anemones, tube anemones, and zoanthids), (2) Octocaorallia (e.g. blue coral, soft corals, sea pens, and gorgonians), and (3) Ceriantharia (e.g. tube-dwelling anemones).

What are four features of phylum Coelenterata?
Characteristics. All coelenterates are aquatic, mostly marine. The bodyform is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the hypostome, surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey.
What is the bauplan of class Anthozoa?
Which body form is not present in class anthozoa?
How do Cnidaria eat?
All cnidarians are carnivores. Most use their cnidae and associated toxin to capture food, although none is known actually to pursue prey. The mouth opens, the lips grasp the food, and muscular actions complete swallowing.
Which is an example of a class Anthozoa?

Examples include sea anemones, sea pens, and corals, with an estimated number of 6,100 described species. Sea anemones are usually brightly colored and can attain a size…
What kind of corals are under the phylum Anthozoa?
The class Anthozoa (under the phylum Cnidaria) includes corals, anemones, sea pens and seafans.
Where are Coelenterata found in the animal kingdom?
Phylum Coelenterata belongs to the Animal kingdom found usually attached to the rocks at the bottom of the sea. They are multicellular and can be found in colonies or solitarily. These are the simplest group of invertebrate animals. These are mostly aquatic animals. The mouth is surrounded by short and thin tentacles.
What are the three different types of coelenterata?
Classification of Coelenterata. Coelenterates are classified into three different classes: Anthozoa; Hydrozoa; Scyphozoa; Hydrozoa. These are mostly marine species, found exclusively in freshwater. Few are found in colonies and few are found solitarily. Asexual Polyps is the dominant form. Mesogloea is acellular. E.g., Hydra, Obelia. Scyphozoa
