Armina sp. (undescribed)

Well, with all the diving that has been done in Bali and all the Nudibranch Workshops that have been held there how did this one slip by?

I am calling this critter an Armina, rather than a Dermatobranchus because the anterior edge of the mantle, behind the rhinophores appears complete, not fused into the head. Wish we could see the gill to be sure.

In most species of Armina the longitudinal lines on the dorsal ridges are a light color on a darker background. In this species we see the reverse - dark blue line on a white background. The edge of the mantle and foot is bright yellow as is the oral veil. One unique feature is the bright blue rhinophores.

Wish we knew more about this species. Better yet, wish we had a couple of specimens.

Scott Johnson with friend at Elephant Park, Bali, Indonesia

Scott and Jeanette Johnson certainly need no introduction to the readers of this site. Scott shoots the video and Jeanette the stills! Scott and I are kindred spirits in our video aspirations(actually Scott is already there, I'm doing the aspiring). We both shoot video of sea slugs although in my case, it is often to the exclusion of other subjects. I recently made a trip to Isla Mujeres in Mexico to swim with the whale sharks and take video with my GoPro as a short lived diversion from macro videography. What a disappointing experience! The GoPro performed well in the total chaos that prevails there but otherwise it was a total bust! There were 75 boats in a one mile square area with a very limited population of whale sharks feeding! I'm getting off topic but came back from that trip fully resolved to continue videoing my friends the sea slugs.

Anyhow, Scott and I both face the challenge of what path to take in the way of upgrading our equipment. Our systems are dated but you would never know it considering the quality of Scott's image above! Scott is using a Sony HC-9 and I go further back with an HC-3! The whole question of where to go video wise has been a continuning topic at our video club meetings. Several members are already moving into 4k as affordable 4k monitors are just now becoming available in the states for less than 1K. Well, to see 4k on our monitor we need 4k video capapbility. That is going to cost us around 2k for a camcorder! The camcorder begets a housing and now we're looking at another 3 to 4k. Let's see! We haven't even considered, UW lights,a new computer to process the 4k video, and the 4k TV to watch our video! You can see the 4k approach can be a path to the poor house!

Let's see, a nudibranch video in 4k! I love it! But given the economics of getting there, think I will stay in the standby mode a bit longer!
