Introducing P. cremoniana! While on a dive, searching for tiny critters, I came across this little fella, the likes of which I have never seen before.
Update March 2016: This slug’s DNA was not matched to any other species and so it has been described as a new species and named after yours truly! Placida Brookae
Just in time for Halloween, this tiny critter makes its appearance in Southern California! I have written an article that has been published in California Diver Magazine, so rather than reiterate the entire story here, I will refer you to the magazine, where you can read it in its entirety. Suffice it to say that I am very pleased to have found the very first sea slug of it’s kind in Southern California. This little guy originated in the Medeteranian, and has been found in the Western Pacific and also Mexico, but never as far north as California.
My obsession with nudibranchs continues, even though this guy isn’t technically a nudibranch. (It’s a sea slug) It still has the beautiful colors that are typical of nudibranchs and the fascinating cerata and rhinophores, but lacks a gill plume. It is unique. And tiny. It was no larger than the head of a pin, about 3 or 4 mm, although I have read they can get twice that size. Still. T I N Y!
