The 29th day of #Nudivember brings me to my last post for a few days as I will not be near a computer nor my stash of nudi pictures. Sorry about that. When I do return, I will be busy with inverts. So please stand by #MarineLife

This is a little guy again but I did not have time to grab my compass
This nudibranch has a white translucent body with small white dots a white line along the foot and a yellow line on the mantle. It is moving across a bed of algae Diaphorodoris luteocincta

This morning, we are getting another one of the little ones, something like 4 or 5 mm long. This might be one of two, either an affinis or pedata. My guess is the pedata but...

#Nudivember #MarineLife
A transparent ruler showing black CM markings with a nudibranch above and behind the edge. The nudibranch is about 4 to 5mm in length, with a mostly purple body and whitish to light tan cerata with white tips on a bed of algae It might be a Flabellina affinis but most likely is a Flabellina pedata

Happy Turkeyday to those who celebrate. #Nudivember is drawing to a close and I am going to take on a new quest for next month, probably inverts but we will see. #MarineLife

read the Alt, you are welcome
This little guy is quite the colorful little thing. Black body with yellow strip accents along the mantle though not completely. The head seems to be white with a short yellow stripe between blue rhinophores, The gills are a translucent purple and blend into the body in a blaze of yellow with hints of red. Like I said, quite the colorful thing. Nembrotha megalocera.

So, a late start again to posting on this 18th day of #Nudivember. #MarineLife

The ass end of a nudibranch and the naked lungs central in the picture.

There are white spots aligned lengthwise on either side of central line in yellow which starts behind the gills, contouring them and ending between the rhinophores.

Today, day 17 of #Nudivember, I bring you a somewhat badly lit but sharply focused picture of a Felimare villafranca

If the bloody Dutch national team actually plays attractive football tonight, I will be posting orange thingies in the coming days in their honor.

I am just going to say that I think my diving gear is way cooler than yours. Prove me wrong. (Pro tip, you will not manage to do that)
A Scubapro regulator setup with the two second stage pieces prominent in the picture. The closest is a converted Pilot with pink mouthpiece. In the background is the Adjustable SP109 with a white translucent mouthpiece. Both show signs of the classic green corrosion of brass from excessive use in salt water. I bought the 109 in 1974 and the Pilot in 1979 and together, they have dived around the world and spent an estimated 13,000 hours under water, reliably supplying me with air. I still use them to this day

Well, here it is late in the day off 16 #Nudivember and I have yet to make that post... Today I give you a twofer. The second picture is a crop of the first

#MarineLife
The scene is from a late afternoon dive with large rocks covered by algae and different organisms. At the center are two nudibranchs from different species. The lower one (F. babai) has a translucent white body with orange tipped cerata and rhinophores. The upper one (C. papillata) has a translucent white body with small branched papillae which are orange, like its rhinophores. Flabellina babai (I think they have given this one a new name but my book does not self update.) Crimora papillata

For the 15th of #Nudivember, I am posting something splashy, colorful, out of the ordinary but then I realized that nudis are just that! #MarineLife

While you were distracted by pretty colors in a busy scene with anemones, algae and sponges, you looked right at a nudi, in the center of the photo.
Pretty colors and a busy underwater scene with anemones, algae and sponges, and there is a nudi in the center of the photo. The nudibranch has a blue body with a yellow mantle and stripe down the center of its back with two lines of white spots also along the back #Felimare tricolor A cropped version of the last photo showing the previously decribed nudibranch in the center of the photo

It is #Nudivember, the 14th. #MarineLife never looked so good! (That is a lie of course. It has always looked good!)
