shark egg identification please

My hubby brought this home today and it was labeled "bamboo cat shark egg" That's what it was sold to the pet store as. I don't always think the distributors know what their looking at so I did some photo recon. It don't seem big enough or wide enough for a bamboo. Seems more like a swell shark but I am not an egg expert. This is my first egg. (not my first shark) Have been keeping sharks for a long time just first egg. Can anyone tell me what this baby is?

Heres another pic with candling

Thanks guys. Cool. I love the cats. How long of a hatch day are we talking with these guys.

Thanks guys much appreciated. I can deffinatly see stripes on him already. With coral cats do they start out with stripes? Mine was well out of the egg when I got her so don't know if she she had strips before the dark pattern with the white spots.
