Filmed on a circa 2005 model flip phone! This sea cucumber (Sclerodactyla briareus) was collected near Woods Hole, MA. We found that we could induce spawning behavior by raising its water to room temperature, and acclimating it to a light cycle. Yes, that's an old canning jar. At rest, it was probably only 2 inches long, but became greatly elongated and extended its feeding tentacles when spawning. It began a slow rocking motion as large (a few hundred micron) gray eggs with a thick, transparent jelly coat were expelled. These eggs can be seen as black dots on the bottom of the jar when the camera takes a higher angle.

Hmm…it looks like things are taking a while to load. Try again?
