A few weeks ago I started looking for this Nudi, and it is by no means a new critter, but it is a fun one to look for. It has taken me a few weeks to start posting due to a couple of reasons, a visit to Malaysia for a week, and a hard drive crash which made all my data unavailable on my drive (thanks to ‘Data Rescue 3’ i got almost every file back).
So, onto the Nudibranch, there are 2 in this photo:
The Nudi in question is in fact a sapsucking slug, Costasiella kuroshimae. According to the book they get upto 7mm long but these were about 2mm long. They live on Halimeda Algae and once you find one, you fins millions. Look for the large halimeda algae that only has one leaf on TK, Hairball and other sandy muck sites.
Images shot with Canon 5Dmk3, Nauticam Housing, 100mmL lens and stacked +10 and +5 Subsee Diopters. 1/60th Sec f/25.
We have some new developments at the resort that we’ll be posting soon, keep checking the blog or subscribe!
