Diver with a live ateleopodid identified as Ijimaia   sp. from  tamar.org.br. Jellynoses can be rather big fish — up to 2 meters long — but I’m sensing some forced perspective in this photo. Recently an I. antillarum made the news when it was captured off Florida, and judging by the comments I’ve seen, this group of fish is almost unknown to the public.

Fan-art of a recently (semi-) published hypothesis: that the bizarre internal structures on beaked whale skulls may be used for ‘visual’ sexual display, despite being surrounded by soft tissue. Apparently this bone — some of which is the most dense known — could still be detectable to an echo-locating beaked whale. Show More Summary

A reconstruction of Spinosaurus by Luis V. Rey based on a new version by Paul Sereno. It would appear that new material has been discovered and not yet published — however, even Rey himself is uncertain of this. The extremely short legs and near-quadrupedal posture just… could not look weirder. From the art blog of Luis V. Show More Summary

Shaw's Lophius monopterygius from The Naturalist’s Miscellany. After initially classifying it as an anglerfish, Shaw had doubts and wondered if it was actually a dugong fetus or a cetacean of some sort.  Shaw’s description is terrible, but it refers to a real species — the Coffin Ray — and as such it still carries his specific name, Hypnos monopterygius.
