Bump is a forum term meaning that I am bumping the topic to the top spot in the "New Posts" webpage for more users to see it and hopefully one of them will be able to answer you. I have no clue what it is, and I bumped it so that I could also find out what it is.

This is interesting, I'm just gonna follow along because I wanna see what it is too.
It definitely came from something BIG. My closest guess would be conjoined shark eggs.

Maybe sac after fish gives birth. Like placenta for humans. BUMP.

Is it hard like a shell or fleshy?
Looking at it closer it almost looks like it is an opened up shell. I can make out some kind of hinge in the middle.
It could be some sort of bivalve if its hard. If its fleshy, could be some kind of internal organ or if you could dissect it and find organs inside it could be something completely different.

I don't know of any saltwater fish that give live birth.
Actually:

Some sharks lay eggs, others give birth to live young.

Some shark species are oviparous, meaning they lay eggs. Others are viviparous and give birth to live young. Within these live-bearing species, some have a placenta like human babies do, and others do not. In those cases, the shark embryos get their nutrition from a yolk sac or unfertilized egg capsules filled with yolk. In the sandtiger shark, things are pretty competitive. The two largest embryos consume the other embryos of the litter! All sharks reproduce using internal fertilization, though, with the male shark using his "claspers" to grasp the female and then he releases sperm, which fertilize the female's oocytes. The fertilized ova are packaged in an egg case and then eggs are laid or the egg develops in the uterus.

From this picture, I'm thinking it might be a yolk sac that wasn't absorbed.

I actually saw some youtube videos about this and meaning to look back to see more about it but never got to it.
Thanks Nova.
