I just can't wait to see it hatch...

[johnnymisty]

Wow getting bigger

[charles-n-charge]

It looks like he is ready to come out of there... This is so cool.

Not quite. If he came out now, he'd be a goner.
It'll be soon though

This is really cool watching the progress.

I saw that.... Has it hatched yet?

Not yet. It'll probably be about another month or two.

Here's an update:

The yolk is finally starting to shrink and the shark is growing daily

Any updates? Has it hatched yet? It looks like it was running out of room in that egg sack.. I have never seen a baby shark in an egg sack always thought they gave birth to live babies.

I just explained all of that a few posts above you

Wow never knew that!

Reminds of that great white shark show of how they pump water through their gills.

Cool!

I thought sharks gave birth to live young?

Generally, in the aquaria-trade, we break sharks up into two different main categories.
1) Free swimming Sharks (ex: Blacktip Reef Sharks, Lemon Sharks, etc.)
2) Bottom-dwelling Sharks (ex: Nurse Sharks, Bamboo Sharks, etc.)

Free swimming sharks are always on the move, 24/7, because they have to keep water constantly running over their gills to breathe. Bottom-dwelling sharks, on the other hand, have full control over the muscles in their gills and can pump water across their gills without swimming. This is why you can often see nurse sharks laying around on the bottom while blacktips are always swimming around.

Free swimming sharks give birth to live young, because the babies too must constantly be moving in order to breathe, thus meaning they could not sit still in an egg during their development.
Bottom dwelling sharks lay eggs, usually along the coast in the shallows, in kelp fields or attached to seaweed. Because they can breathe without the need to swim, development in an egg in possible.

If you watch some of my most recent videos, you can actually see the baby shark in the egg pumping water through its newly formed gills.

I believe that should answer your question
