Here, an Opalescent Nudibranch (Hermissenda opalescens) was laying a string of eggs on a blade of eelgrass. These eggs are embedded inside a gelatinous substance for protection and depending on the temperature, can start to hatch in about a week (https://cadivingnews.com/sea-slug-courtship-and-reproduction/). The hatched nudibranchs are called veligers and will drift around the water before settling down and turning into adults.
