Invertebrate Zoology 7th ed. These species live in shallow water and many are reef-builders. After fertilisation, the planula larvae form part of the plankton.

This work highlights the importance of the study of ocean dynamics, combining biological and oceanographic observations, trying to understand the role of mesoscale physical processes on the distribution and abundance patterns of species.

Some of these extend from the body wall as far as the pharynx and are known as “complete septa” while others do not extend so far and are “incomplete”. Both species showed a marked seasonal variation in the extent and location of spawning areas.
