HABIT AND HABITAT
Cavernularia is a marine, dimorphic and colonial form.
GENERAL CHARACTERSTICS OF CAVERNULARIA
- Body is divided into a proximal stalk or stem or Peduncle which is divide of anthocodia or polyp and a distal part having polyps.
- Distal part is called as rachis which is covered by perisarc.
- Pigmentation is blue, violet, yellow and green.
- It is the primitive genus in which the rachis is stout radially symmetrical, cylindrical or club-shaped.
- Anthozooids and siphonozooids are distributed over the whole surface of the rachis.
- Coenenchyme or coenosarc is fleshy and is traversed by coenoceral canals containing long spicules.
Cavernularia is bioluminescent coelenterate. It produces light without heat.
The animal’s body is divided into stem and rachis and contains all above parts, hence it is Cavernularia.
