How do sea pens survive?
Each sea pen is a colony of polyps (small anemonelike individuals) working together for the survival of the whole. ... Some polyps feed by using nematocysts to catch plankton; some polyps reproduce; and some force water in and out of canals that ventilate the colony.
How long can a sea pen live?
Sea pens are a type of octocoral, or soft coral, which are related to jellyfish and anemones. They may not get as much love as their glamorous cousins, the reef-building hard corals, but sea pens are fascinating creatures that can live to be 100 years old, glow in the dark and live in the soft sediments of Puget Sound.
What do sea pens do?
Sea pens can deflate or expand by expelling or taking in water through the interconnecting hollow canals of the polyps. They feed on small organisms captured by the tentacles at the end of each polyp. Most sea pens luminesce, or glow, when they are touched or otherwise stimulated.
Are sea pens sessile?
