1. Sea pen

   Sea pens are colonial marine cnidarians belonging to the order Pennatulacea. There are 14 families within the order and 35 extant genera; it is estimated that of 450 described species, around 200 are valid. Sea pens have a cosmopolitan distribution, being found in tropical and temperate waters worldwide, as well as from the intertidal to depths of more than 6100 m. Sea pens are grouped with the octocorals, together with sea whips (gorgonians). Although the group is named for its supposed resemblance to antique quill pens, only sea pen species belonging to the suborder Subselliflorae live up to the comparison. Those belonging to the much larger suborder Sessiliflorae lack feathery structures and grow in club-like or radiating forms. The latter suborder includes what are commonly known as sea pansies. The earliest accepted fossils are known from the Cambrian-aged Burgess Shale (Thaumaptilon). Similar fossils from the Ediacaran may show the dawn of sea pens. Precisely what these early fossils are, however, is not decided.

1. sea pen

   A sea pen is a type of colonial marine organism from the family Pennatulaceae. It is named because its structure resembles a quill pen. Sea pens are similar to soft corals and are found in the benthic zone (the bottom of ocean), particularly in deeper waters. It consists of a primary polyp that forms the central stem and secondary polyps which extract plankton and other nutrients from the water. Sea pens are also able to emit light when disturbed.
