No, this isn’t a scene from The Life Aquatic. What you’re seeing is two biofluorescent catsharks.  

A team of researchers led by scientists from the Museum has found that catsharks are not only able to see the bright green biofluorescence they produce, but that they increase contrast of their glowing pattern when deep underwater. The study, conducted with a custom-built “shark-eye” camera that simulates how the sharks see underwater, shows that that fluorescence helps catsharks see  each other and may even offer them a way to communicate.

Mermaid’s Purse - Catshark Egg Case

Many species of catshark (family: Scyliorhinidae) lay eggs in tough egg cases known as mermaid’s purses. These cases have curly tendrils that tangle around objects to prevent them from floating away.

The gestation period of the egg can range from a few months to over a year, depending on the species and water temperature. If held against a light source, the developing embryo can easily be seem.

Scientists developed a special camera so we can fully appreciate glow-in-the-dark sharks

The concept of glow-in-the-dark sharks is infinitely intriguing, so naturally, science developed a new camera, the better to see them with. As the Washington Post reported, its lens mimics the eye of a shark, allowing researchers to see sharks as they see one another whilst sharking around in the deep sea. Here’s what they discovered about the colors the sharks glow.

How about mallow as a leafy sea dragon? :o I've also been trying to figure out what Ilima would be but I haven't found anything that fits; Have you found something for him? I like to think that his smeargle would be a cuttlefish tho, cuz of the color changing and what not :D

mallow as a leafy sea dragon would be a perfect choice!! i love it! as for ilima, ive chosen a chain catshark due to its coloring and its wonderful markings! they’re bright colorful eyes, which ilima certainly has….(and a cuttlefish would be perfect for smeargle!)
