This is a gif of a giant hyperiid of the genus Cystisoma, a completely transparent marine space alien. The bulbous portion of its body is actually its head, of which its eyes make up the entire top half. No word what Mother Nature was thinking when she invented this particular creature, but I suspect there was a bad breakup involved. "Father Time broke my heart!" Awww, there, there, Mother Nature, you're better than him -- he doesn't deserve you. Now, pick up some of that magical life clay of yours and sculpt me a sexy mermaid companion.
Thanks to Dave L, who told me he feels like that hyperiid sometimes. Wait -- creepy or invisible?
