Nov 19th, 2016: Two Headed Shark
 

From National Geographic...

Sans-Coma and colleagues say a genetic disorder seems to be the most plausible cause for the two-headed catshark.
But wild sharks' malformations could come from a variety of factors, including viral infections, metabolic disorders,
pollution, or a dwindling gene pool due to overfishing, which leads to inbreeding, and thus genetic abnormalities.

Saw thread title...

...was not disappointed.

These have been cropping up more and more! Most are blue sharks, which is thought to be due to the large number of eggs (50+) each female produces each breeding season. Whether the cause of the two-headed babies is genetic or environmental is under both debate and study worldwide. Recently, a scientist working with one of the small shark species noticed a conjoined/malformed embryo inside an egg case (most of them are called mermaid's purses, and there are some WEIRD shapes), the first time one had been found in a species that produces encased eggs. Also real: the albino cyclops shark embryo: http://tinyurl.com/zgbgyq3 found in a dusky shark several years ago off the Mexican coast.

It's gettin' WEIRD out there, and when the going gets weird the weird turn pro!

As a youth I had pet snakes. One of them produced several babies, one of which had two heads.

Yeah, snakes...
