Description

Feathery sea pens stand upright in the sand like the quill of a feather. The central axis has flat branch-like extensions on which the polyps are clustered. They are usually white or cream. The peduncle is very long and the entire colony can retract into the sand if disturbed. This species may grow to 50 cm in height and is about 1 cm wide.[4]

Distribution and habitat

The Feathery Sea Pen is known from Luderitz in Namibia and round the southern African coast to central Mozambique in 6-222m under water. It lives in sand and feeds on micro-plankton.

gollark: It is pretty great though; for instance, I can see that from 07:28 to 18:44 CPU usage was at slightly over 14% on all cores for no apparent reason.
gollark: I wonder if I can make it downsample older stuff.
gollark: I'm pretty sure this will eventually accumulate several gigabytes of unnecessary time series data but oh well.
