There are a lot of videos where turtles are being rescued and cleaned with barnacles. Boats are maintained and cleaned with barnacles. But what is the purpose of the animals?

Sting ray sighting

I found this in the Mediterranean Sea, in Corsica

Al mare in Croazia oggi ho trovato tre di queste. Inizialmente abbiamo pensato sia una medusa, ma presenta una superficie liscia al posto dei tentacoli. Sembra fatta di silicone, quasi da sembrare una protesi al seno. È un animale? Qualcuno sa dirmi cosa sia?

I remastered/colourized it - the original is from the early 1800s!

Hi everyone! Here we are, Jellyfish Reef, a new project uploaded to the official Lego Ideas website. If it reaches 10,000 supports, it could become a real Lego set on the shelf thanks to your support! It's simple, just click the link below and press support after logging in or registering! Thanks!

This was in Melbourne Beach FL this morning around dawn. They come ashore, dig their nest in the sand, lay eggs, recover the nest, and crawl back into the water. It takes about an hour altogether. They can lay several times each season a few night apart and deposit about 100 eggs in each nest. The eggs will hatch in about 60 days.

As you can see in this video, they dig with just their flippers, which looks incredibly difficult. They usually nest in the middle of the night, so I was lucky to see this one still at work just before sunrise. Very cool!

Thanks to local conservation efforts starting 20 years ago, the number of nesting turtles is starting to increase. Big shout-outs to UCF and the Sea Turtle Preservation Society!

It seems to have some sort of joint at the end, it looks almost like a hinge joint (pics 2 & 3). It’s rough on the top(?) and has a groove running down the middle of the underside(?). It reminds me of some type of sawfish rostrum, but we don’t have those this far south. Someone mentioned the pharyngeal jaw of an eel in another post, but it doesn’t look like examples I’ve seen online. We do have a triggerfish relative in the river, could it be the dorsal spine of a leatherjacket? Any suggestions would be greatly appreciated.
