Aliens? Fish? Nope, neither. But what exactly are these little, jelly-like "creatures" that have been washing up on the beach in Huntington Beach, Cali.? Let the speculation begin!

A number of photos have been popping up on social media recently with people questioning exactly what these little critters were. They have the consistency of little water balloons. And they're a living species, also! Christopher G. Lowe, a marine biology professor at Cal State Long Beach, said that the little things are actually "sea cucumbers." They live at the bottom of the ocean and were probably washed up because of a recent storm.

That's kind of a bummer of a solution to this whole mystery. We'll stick with aliens. Definitely aliens.
