Abstract:At present we have little evidence that successional
changes following predictable patterns
occur among epifaunal communities living on
natural rock-reefs in the shallow sublittoral of.
the open ocean. If this phenomenon does occur
here, it can be detected by sustained observations
at a single study site. In the period from
1957 to 1960 I conducted an intensive study of
the epifaunas of two submarine hogbacks located
at different depths off the coast of Corona
del Mar, California. Some observations made
during this period indicate that both gradual
and disruptive changes do occur in these epifaunal
communities. Attention is called in this
paper to an abrupt change in population density
of a predominant species that occurred on part
of the shallower reef, and to the widespread
biotal adjustments that ensued.
