Watch out – those beautiful orange strands pack a punch!
Some nudibranchs eat hydroids and anemones, which have stinging cells in their tentacles. When they eat the stinging cells, these nudibranchs can transfer some of them to their cerata, reusing their prey’s defense mechanism as their own. This nudibranch was spotted in Greater Farallones National Marine Sanctuary.
