The results of these extensive studies, published in the journal "Deep-Sea Research Part I," indicate that the evolution of nudibranchs is much more flexible than previously thought. Bathydevius ...

Bathydevius caudactylus has a metabolism much lower than that reported in other nudibranchs; in fact, respiration rates are more similar to those MBARI researchers have recorded in deep-sea jellies.

This method of protection can keep almost all predators at bay - but not the kaleidoscopically colourful sea slug. Nudibranchs, commonly known as sea slugs, are a group of shell-less marine molluscs.

There are spectacular deep-sea nudibranchs as well. Here is a new species of Dendronotus, collected in 2013 and found feeding on hydroids at a methane seep off California. Frenulates are extraordinary ...
