Trapania sp. 13 (undescribed)

Following along with our discussion of undescribed species observed during the April/May Slugfest, in Anilao, at Crystal Blue Resort , here is one more newby, Trapania sp. 13 in Nudibranch and Sea Slug Identification. .

Species of Trapania all have a pair of curved, elongate extrarhinophoral and extrabranchial appendages. Although they are found on sponges colonies, they are feeding on entoprocts ( a small colonial critter) that are commensal with the sponge.

This new species is one of the white body with black spots species. It is differentiated from the other lookalikes by having yellow extrarhinophoral and extrabranchial appendages.

It is known from Indonesia and the Philippines.

Well folks I have a confession to make! I am still shooting slugs with 2005 technology and mini DV tapes but that said-I have no complaints! Most members of our video club have moved on to 4k and even higher 5 or 6k resolution! Guess I'm not quite ready to address the learning curve that goes with 4k video or the impact it will make on the checking account! Am putting up a short video of this week's subject which was somewhat of a challenge at 5mm!
