Translucent “jumping sticks” washing up along Florida’s Space Coast have people asking one question: What are they?

The unusual discovery of dozens of 1-inch moving creatures left one beach-stroller near the Indialantic Boardwalk mesmerized, FOX 35 WOFL reported.

“They were flopping around. They were very active, and that’s what caught my eye,” Diana Duby told WOFL.

Duby initially thought the organisms could have been baby eels, and she wasn’t far off, according to Dr. Todd Osborne, a marine life expert at the University of Florida’s Whitney Laboratory for Marine Bioscience.

They, in fact, fall under the same family of leptocephalus, Dr. Osborne told WOFL.

“That little clear thing — that could be an eel, a tarpon, several different tarpon, bonefish, ladyfish,” Dr. Osborne said.

“They all fall under this class, the same order and they all have the same growth morphology as larvae, which is really cool.”

The mysterious organisms are so young that identifying their exact species is nearly impossible without further investigation.

One person’s chance encounter with the drifting, translucent organisms highlights how much remains unknown about Florida’s coastal marine ecosystems.

“We’ve been cataloging things in the ocean for a couple hundred years, and we still have no idea about what is going on out there,” Dr. Osborne told WOFL.
