Concerning Sharks: Sort of.

Footage was caught of a ghost shark. Little is known about these oddities, however, they are probably a completely different species: although, related to sharks.

Also known as deep sea chimaeras, they are definitely not "lookers". The ghost shark researchers were able to film, was covered in parasites, and they claim it didn't look healthy. It makes me wonder, and dread, what other species may be facing. Is this shark's condition an anomaly, or are other sharks facing similar conditions? More importantly, is this a consequence of our callous actions, or is the cause natural? Regardless, I believe, more research should be done, to determine why this animal looks the way it does, and what is the cause for its parasitism.
