Flatworm-like Jellyfish

A new species of jellyfish was found in the seahorse tank at the Townsville Aquarium in Australia. (News source.) It is described:

"'It's up to about a centimetre long, it doesn't swim, it glides along the bottom,' she said.
"'It's found on algae and seagrass and it's just a real thin film, real mucusy like a flatworm but it's got these two tentacles sticking out and it's actually genetically a jellyfish that looks like a flatworm.'"
