Guest post by Robin Agarwal California has about 180 known species of sea slugs Most of California’s approximately 180 known species of sea slugs (nudibranchs and related species) were described in scientific literature decades ago. Only a handful of these sea slugs are regularly seen and documented, but have not been formally described. These species remain on scientists’ collective “to-do” list, including: Doto Form A of Goddard (1996) One of the most common Dotos on the Southern and Central California coast, its pinkish cerata are covered with white-tipped tubercles. Its rhinophores have a prominent cup-shaped sheath and are tipped with …

While not everyone can be a marine biologist, a meteorologist, or a conservation ecologist, anyone can contribute to the wealth of data that these experts use and study. Our own Monitoring program uses data gathered by community scientist volunteers and staff members to keep an eye on long-term trends in water quality, bacteria levels, and other factors that influence stream and bay health. (We are not working with volunteers at this time due to COVID-19 precautions, but we look forward to having our volunteers back in the field as soon as it’s safe to do so.) Today, we’re sharing …

Spotted Triopha or Triopha maculata One of the most charming creatures found along the Central California coast is the Spotted Triopha nudibranch (Triopha maculata). With its colorful body, white polka dots, and bushy “beard”—properly called papillae—on the edge of its oral veil, this engaging sea slug is one of the most common you’ll encounter year-round, either on a dive or during a casual inspection of tidepools at low tide. Triopha maculata color variants The only minor difficulty is realizing that you’re looking at one. Spotted Triophas come in at least two color variants that caused even veteran scientists to …

“Whoaaaa…what is THAT?” “It’s gorgeous, whatever it is.” “It’s moving!” “Dude, check this out!” “So BLUE!” “What IS it?” Music to a science educator’s ears, of course, thanks to the astonishing colors and reasonably viewable size of one of California’s most iconic sea slug species, the Opalescent Nudibranch (Hermissenda opalescens). Found throughout the Central California coast, these brightly-colored carnivores are often the first nudibranchs to astonish and delight the humans venturing into their intertidal world during seasonal low tides.

What is Snapshot Cal Coast bioblitz? During a bioblitz, citizen scientists document all living things in a certain area, during a specific period of time. Estuary Program staff and volunteers participate in an annual bioblitz called Snapshot Cal Coast, which is hosted by the California Academy of Sciences. This large-scale effort aims to document plants and animals all along the California coast, during a particular week in June. Participants are asked to complete their bioblitzes in Marine Protected Areas (MPAs) and to focus on intertidal zones (those areas that may be submerged during high tide and exposed during low tides).
