RFPCDT6J–This is a sea pen (Virgularia gustaviana: height 12 cms.) with its numerous eight tentacled polyps feeding in the current. Sea pens are most commonly encountered on sandy or silty substrates, to which they attach themselves by a bulbous 'foot'. A soft coral colony, it consists of a central stalk from which branches extend on either side. The polyps live on these branches and, when resting, fold their tentacles inwards to form tiny balls. If threatened, the whole colony can be retracted into the substrate. The common name is because they reminded people of feathery quill pens. Bali, Indonesia.
RFPT7X6H–This soft leather coral (Sarcophyton elegans: diameter 30 cms.) is found commonly on reefs in the Indo-Pacific region. Attached to the substrate by a short thick stalk, its 'mushroom-shaped' top - called a capitulum - extends into the water column in a series of folds. When resting, the polyps are retracted, giving the colony a smooth appearance. The leathery base contains toxins, which discourages potential predators from eating it. In a current, the colony's many eight-tentacled polyps are extended fully (as in this instance) in order to catch passing zooplankton. Hurghada, Egyptian Red Sea.

RFMTA6K1–The orange colour and black markings of the flamingo tongue cowrie (Cyphoma gibbosum: 1 cm.) are formed by the mollusc's mantle, which covers the animal's shell. If alarmed, the mantle is retracted to avoid predation; clearly, the snail was not perturbed by my presence. The species lives in the warm waters of the Western Atlantic, the Caribbean Sea and the Gulf of Mexico. It is usually found on sea rod gorgonians (as in this case) where it feeds on the coral's polyps. Sadly, they are becoming rarer, mainly because they are taken for the aquarium trade. Photographed in the Cuban Caribbean Sea.

The largestspecimen has a capitulum measuring 12 mm in width, whereas the stalk is2-3 mm in width. The capitulum is dome-shaped or elliptical with the polypscovering the entire surface. Polyps are dimorphic. The retracted anthocodiae ofthe autozooids may form small protuberances on the surface of the capitulumbut these are not true calyces, since the protuberances are capable of completeretraction into the capitulum.
