Horned aeolid, Hermissenda crassicornis
The cerata of this egg laying Hermissenda crassicornis are disheveled by
the water's surge, while its two annulate rinophores protrude upward. Visible in
the background is a colony of Corynactis californica that lines a cavity
in the tracks of a sunken World War II era amphibious landing tank. These
vehicles are commonly called "amtraks", a condensation of "amphibious tracked".
Hermissenda is one of many creatures in Monterey that, from time to time,
appear in large numbers. This specimen was one of perhaps several hundred that
had aggregated on one side of an amtrak.
