Aglaja ID help?

[cozcharlie]

I am guessing this is some sort of aglaja. Anyone know? Perhaps @jlyle ? I gather the black aglajas (now I guess migaya felis )sometimes have some white or grey markings but this is pretty extensive.

Paradise is full of aglajas right now, especially on the sand just inside the reef down near the cruise ships. Literally saw hundreds if not thousands yesterday (Leech , Cubans, whatever this is as well as a flapping dingbat or two )

Interesting. I'm seeing thousands of the black ones but not ones with markings.

"Note that not all Migaya felis are solid black, but may have white lines and spots or a grayish under color. This species is a good example of the difficulties in both common and scientific names." From Mickey Charters book updates, Caribbeana Reef Life. I learn something new every day.

I read the same passage before posting, but these markings seemed like more of a pattern than random blotches and stripes. Also didn't fit the pictures of black aglajas with white/grey markings I found and those I have seen (seen a few with white blotches before). I still lean slightly towards black aglaja in absence of alternative, but far from sure . The one photo almost showed a maroon center through the divide in the two halves (scubaboard killed the resolution). Not great photos since I wasn't set up for super macro, but cropped originals still look better than the posts. I intended to go back today. but changed plans to accommodate friends. Will go again in next 48 hours

I'm looking for them, too. More images would be better.

Thanks Jim,
You have slug (expert) friends , I have friends who are just plain slugs. I got a couple of photos today where the solid color was more red/maroon than black. Will post tomorrow

I've taken a few photos of the slugs that show a reddish color. It's hard to light a black object on a white sand background! Since your post, I've looked at hundreds of the little buggers but haven't seen any variations.

Photos below from yesterday at Paradise.. A lot redder. I guess its possible camera had a hard time with white balance in earlier photos, but I went back at first photos and didn't see any obvious red flags. Photos still heavily cropped unfortunately. Was going to take more photos but I cleared my mask and then couldn't find it again.
