Types of Anthozoa

Alcyonacea​
Alcyonacea​

Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals, soft corals and gorgonians. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton.

Black Coral​
Black Coral​

Though black coral's living tissue is brilliantly colored, it takes its name from the distinctive black or dark brown color of its skeleton. Also unique to black coral are the tiny spines that cover the surface of the skeleton, the origin of the nickname little thorn coral.

Brain Coral​
Brain Coral​

Brain Coral (Diploria labyrinthiformis) Taxonomy: Domain: Eukarya Kingdom: Animalia Phylum: Cnidaria Class:Anthozoa Subclass: Hexacoralla Order: Scleractinia

Discosoma​
Discosoma​

Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals, soft corals and gorgonians. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton.

Inaria​
Inaria​

Inaria is an Ediacaran fossil. It is found in the Chace Range in Australia, and the White Sea area in Russia. It has radial symmetry and has been described as a tentacle-less cnidarian.

Rugosa​
Rugosa​

Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals, soft corals and gorgonians. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton.

Sea Anemone​
Sea Anemone​

Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals, soft corals and gorgonians. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton.

Sea pen​
Sea pen​

The anthozoans are divided into two subclasses. The members of Hexacorallia, like sea anemones, tube anemones and stony corals, have a sixfold radial symmetry. The number of tentacles, for instance, often come in a plural of six.

Stony Corals​
Stony Corals​

Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals, soft corals and gorgonians. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton.

Tabulate ​Corals​
Tabulate ​Corals​

Tabulate corals with massive skeletons often contain endobiotic symbionts, such as cornulitids and Chaetosalpinx. Like rugose corals, they lived entirely during the Paleozoic, being found from the Ordovician to the Permian.

Tube-Dwelling ​Anemone​
Tube-Dwelling ​Anemone​

Tube-dwelling anemones or ceriantharians look very similar to sea anemones but belong to an entirely different subclass of anthozoans.They are solitary, living buried in soft sediments. Tube anemones live inside and can withdraw into tubes, which are composed of a fibrous material made from secreted mucus and threads of nematocyst-like organelles known as ptychocysts.

Zoanthids​
Zoanthids​

Zoanthids can be distinguished from other colonial anthozoans and soft coral by their characteristic of incorporating sand and other small pieces of material into their tissue to help make their structure (except for the family Zoanthidae). A main characteristic of the order is that their tentacles are all marginal.
