Sea Whip
kc3803-14

Sea whips are several genera of corals of the order Gorgonacea, characterized by long, whiplike growth [1]. The whip is a colony of tentacled polyps growing one upon one another in a continuous single stem. Spicule needles of lime are embedded in the polyp which provides firm, flexible support for the whip [1].

Sea whips differ from sea pens in that the sea whip polyps come directly off the center stalk, whereas sea pen polyps are on branches from the central stalk.

Sea cucumbers perched on a sea whip.

This is a symbiotic relationship called commensalism, wherein one species obtains food, shelter, support, locomotion, or another benefit from the other, without harming or benefiting it. The sea cucumbers are using the whip for support to feed higher up in the water column, where they feed off particles and organisms drifting in the current
