Sorry for being away for so long, did not feel like writing though I have so many posts in my head.
Anyway, here is Promachoteuthis sulcus. It has human looking teeth. It is a species of squid and only one specimen has been found to date. It was captured in the Southern Atlantic Ocean at a depth of 2,000m in 2007.
Reminded me of the movie Aliens straight away.Source: link
