Research help on shark eggs

[Osiris]

This topic has been briefly discussed before, am looking for intel on these:

Am just researching them, would be a neat project to study them. But am finding very litle in regards to the care of the egg itself, like current, temp, etc.. turning, needing lamp like MH over it, etc.

Well in regards to caring for the egg, there's not much to do. It should be clipped on the side of the tank with something like a Nori clip to keep it off the sand. I'm pretty sure they do not need to be turned, nor do they need strong light.
The shark hatches within a few months and that particular shark is a brown banded bamboo shark. It reaches a length of up to 36 inches or more as an adult and needs at least a 300 gallon tank full grown. In the eggcase, they absorb their yolksac and will spring open the egg case when they become strong enough. One should wait a week or so before feeding and I've read the best starter food is live ghost shrimp acclimated to saltwater. As juveniles they are a brilliant black and white striped shark, but in a few months when they reach a foot or so, they lose this color and soon become a drab brown.
Wetwebmedia has some information on shark egg cases.

I have hatched several in a 10G tank, on the sand with standard NO lighting. Moved to larger quarters once hatched.

The mother usually lays the eggs while wrapping them around coral, rock, or seaweed. I'm pretty sure.

Many shark & ray eggs have four wispy hooks on them which anchor them to whatever is handy. Some others have a crazy corkscrew shape which wedges them into place. That's how they're secured in the wild, normally on a stalk of gorgonian or a stand of seagrass or somesuch. In the aquarium, of course, the risk of being eaten by a passing crab on the bottom is removed, so this isn't quite as important, and as long as you monitor to keep the egg clean of suffocating buildups, it should hatch fine. You can shine a bright light through them occasionally to check their progress, but not too often, please.
