Gyrineum roseum (Reeve, 1844)
Rosy triton, 24mm
Gyrineum
roseum is moderately
common on Marshall Islands lagoon pinnacles and on the seaward reef, usually
found under rocks at depths of 6 to 20m. At night it is often seen crawling
on the walls of small ledges and caves.
This one has an egg mass deposited
on a blade of algae.
Not sure how this happened. This
still-living Gyrineum roseum had its spire overgrown with a colonial
tunicate, effectively cementing the shell to the undersurface of a rock. How
long did that take? How long could he have survived like that? What was he eating?
Puzzling. I pulled him free.
