Valentine’s Day is coming up, but this is no ordinary rose – it’s a Hopkins’ rose! 

This bright pink sea slug can be spotted in the tidepools of Monterey Bay National Marine Sanctuary. When tidepooling in search of these little invertebrates, tread lightly! Tidepools are fragile habitats and it’s all too easy to crush their tiny inhabitants.

The Alabaster Nudibranch can be found in the temperate waters of the Pacific, from Alaska to California and along the coasts of Russia and Japan. The beautiful, wispy white tipped cerata are actually the animal’s lungs. But don’t let it’s delicate form fool you, this nudi’s jaws are strong enough to crack open the shell of a snail, one of its preferred meals - photo taken at Seattle, Washington

Wanted to draw something quick before bed so here. Have a lettuce slug because they are beautiful and good and pure and I have one and I love her.

Ceratosoma trilobatum

Ceratosoma trilobatum is a species of colorful dorid nudibranch, a sea slug, a shell-less marine gastropod mollusk in the family Chromodorididae. This sea slug is widespread throughout the tropical waters of the Indo-Pacific area, from the oriental African coast to Japan, Red Sea included.Ceratosoma trilobatum can grow to a maximal size of 15 cm length. It feeds on sponge.

Watersipora Wednesday! Here two opalescent nudibranchs crawl over the invasive bryozoan Watersipora subtorquata in Monterey Bay National Marine Sanctuary. 

Watersipora, the rust-colored, lobed mass pictured here, is an invasive genus of bryozoan – or aquatic filter feeding invertebrates – that has taken up residence in and around the sanctuary. Though there’s still much to learn about how these organisms grow and thrive, Watersipora are thought to have been introduced to the California coast by hitching a ride on ships and boats traveling along the coastline. 

These bryozoans have proven difficult to control because research shows they can be resistant to antifouling paints commonly used to prevent attachment of aquatic organisms to the hulls of ships. Once settled in a new environment, Watersipora can have damaging effects on native invertebrate species, smothering them and outcompeting them for space. But researchers at Monterey Bay National Marine Sanctuary have been working hard to understand how these organisms grow and thrive, and what ecological consequences we can anticipate from their spread.
