Discodorididae
Imagine descending into the depths of the Northeast or Eastern Pacific, and spotting a vibrant splash of red clinging to the seafloor. That might just be *Rostanga pulchra*, the Red Sponge Dorid! These nudibranchs, also known as sea slugs, are a delightful find for any diver or snorkeller. Their bright colour makes them stand out against the often muted tones of the benthic environment. While their exact size isn't well-documented, they're likely small, so keep a sharp eye out! Because they live in the neritic zone, they are often found at depths around 102 meters. It's a treat to find these little guys on your dives!
The Red Sponge Dorid is primarily identified by its striking red or orange-red coloration. Its body is elongated and somewhat flattened, typical of nudibranchs. The surface of its body may appear slightly bumpy or textured. Look for its gills, which are typically arranged in a circle on its posterior end. These gills are often paler in color than the rest of the body, providing a subtle contrast. Finally, observe its rhinophores (sensory horns) on its head, which will also be a matching red colour.
