So I got a picture message from Neglected Shoe...

That picture was posted on Reddit, I don't know any of the people involved. Although Xavier seems like a standup guy.

I've been looking it up (don't want to sleep, clowns will eat me). Here is the info I've found so far, attached to this image.

SHARK EMBRYO in a JAR
#S-875. REAL Shark-in-a-Bottle. Jar is 8" high, holds a real dog shark embryo. Pregnant sharks, when frightened, will spontaneously abort their unborn babies. Divers find these in nets, and collect them for cancer research. Overstock is sold for educational purposes, such as our store, or they are used for dissection in Biology classes. $39
includes priority insured shipping in U.S., shipping to Canadia please add $8, anywhere else in the world, please add $17

There is also the larger variety (which is not for sale).

Also Marvin shows up on the second page of the google images search for Shark in Jar. I saw it and thought 'I recognise that shark'.

Wow, Marvin is internet famous. I wonder what he'll do with his new found celebrity.

Mmm... Shark embryo...
