A soft coral in the order Pennatulacea and subclass Alcyonaria. A sea pansy is a colony of polyps having different forms and functions. A single, leaf-like, giant primary polyp up to two inches in diameter forms the anchoring stem (peduncle). This peduncle can be distended to better anchor the colony in the substrate.The primary polyp possesses secondary polyps, autozooids (feeding polyps) and siphonozooids (serve as intakes for water, which circulates within the colony and helps keep it upright) on the upper surface.The sea pansy is bioluminescent when disturbed, due to Green Fluorescent Protein.

An epithelial and connective tissue membrane that lines body cavities and covers visceral organs within these cavities. Epithelial cells constituting this membrane secrete a fluid (serous fluid) to the membrane's surface, which keeps the membrane moistened; also called "serosa".

Any species of eel in the family Congridae. Conger eels have a thick cylindrical body and tapering snout. They possess a smooth and scaleless skin and large pectoral fins. They are much less common than moray eels in coral reef communities. During the day they tend to hide in crevices and holes under rocks or coral, or burrow into sand. They emerge at night to feed.

Feather stars are echinoderms in the class Crinoidea. The juveniles attach to the substrate by a stalk with rootlike branches. The mouth side faces upward. In the adult stage they break away from the stalk and move about freely.They possess appendages, known as cirri, attached to the underside of the body with which they cling to to sponges or corals. Some can swim by undulating movements of the arms. Some have five arms, others up to 200.
