Most of us are familiar with land slugs, the slimy little critters that can be found on the sidewalk or in your garden. But have you ever seen one of these in the ocean? Called nudibranchs (meaning “naked gills”), these invertebrates have striking colors, feathery gills and strange looking horns, and can be found all along the coast of California, including in many of the state’s 124 marine protected areas.
Fun fact: the opalescent nudibranch steals stinging cells from their prey and uses them as protection against predators!
