Hi, um, if you don't mind, could you explain what's going on in the video in this post? /post/63500334889/stuckinabucket-skate-fetuses-are-facehuggers ; skates lay eggs correct? How is this one alive outside its egg? I noticed it was tagged "decased egg" and I looked it up but found nothing. :(
That’s a video from the Florida Oceanographic Society, so skate baby is probably being used for research. Skates actually fertilize their embryos in utero and then encase them in a mermaid’s purse (like a shark’s) before depositing them. I think they just took the case off of this fellow so he’d be easier to see! He’s still attached to his yolk, so he’s likely going to be fine.
Here’s a video of a skate embryo still in its egg case.
