Salp colony drifts in the open sea off San Diego- R Herrmann photographer.
A salp is an unusual looking creature that is a free floating tunicate and is barrel shaped. The creature is able to move by pumping water through its body, which is jelly like. When the salp pumps the water through its body it strains it and feeds on the phytoplankton that is in the water. These tunicates are quite interesting to look at because of the simple yet complex way that they move through the water and feed at the same time.
