Frilled Shark

A Frilled shark was recently spotted near the coast of Japan. They are very rarely seen since they normally live about 2000 ft below. You can see a clip of it here.

Unfortunately it didn't last long, perhaps the pressure change meant its internals couldn't cope.

Maybe it's a coincidence but it seems so me that these whale-killing Japanese know only one way to deal with beautiful ocean creatures. Especially this one, from some time ago, astounded and horrified me.

It is claimed that the frilled shark has the longest gestation period of any animal. Is that true?

I don't think they know for sure, it's not been studied properly...

I'm not an expert on sharks, but I do know that the Frill Shark is ovoviviparous, that is, it the eggs are retained in the body whilst they are developing and hatch soon after laying, though the egg provides all nutrient whilst in the mother's body, so the sharklet isn't connected to her bloodstream. I guess this may complicate calculating an exact gestation as it falls somewhere between being viviparous and oviparous.
