P4240090 - Cockerell's nudibranch
P4240026 - Two Janulus fuscus (white-and-orange-tipped nudibranch) around a red-trumpet calcareous tubeworm.
P4236952 - Diamondback nudibranch laying eggs.
P4226764 - An opalescent nudibranch and two diamondback nudibranchs.
P4076439 - Cockerell's nudibranch.
P2095733 - Monterey dorid laying egg mass - contains 1000s of eggs that will hatch out as planktonic larvae). The plume you see at the back end of the nudibranch is the gills. Archidoris montereyensis is up to 15 cm. The organisms around the Monterey dorid and his/her egg mass include brooding anemones, fringed filament worms, and a retracted creeping pedal sea cucumber (orange on the upper right).
P1205410 - Orange peel nudibranch feeding on pale soft coral.
P1065283 - Red dendronotid mating (Dendronotus rufus to 28 cm). Right-side-to-right-side.
P1065202 - Yellow-rimmed nudibranch laying eggs (Cadlina luteomarginata only to 4.5 cm). Each species of sea slug has very distinctly shaped egg masses/ribbons. One of my favourite things is to match species to eggs. Much easier if to figure out if you catch them in the egg-laying act! Notice how the yellow-rimmed's egg mass is two connected spirals?
