Last week I gave you this really nice skull from the Dead Zoo to have a go at identifying:
It proved a little more tricky than I thought it would, but I shouldn’t have been surprised given the poor quality of the photo and the fact that the cranium isn’t properly seated on the mandible (as pointed out by Allen Hazen).
Of course, that didn’t keep you all confused for too long. The large sinuses and relatively undifferentiated and widely-spaced teeth – except for those large canines – suggest that this is the skull of a some kind of seal.
Jeanie and salliereynolds noted the large, depressed opening over the nasal region, which is definitely one of the most distinctive features of this species. However, it also misled in the first place, with discussion of the possibility of it being from an Elephant Seal taking over for a while.
However, salliereynolds got back on the right track, while on Twitter Ray Chatterji was on the right track from the start with his suggestion:

The Hooded Seal Cystophora cristata (Erxleben, 1777) is really weird – well, the male is. He has an inflatable bladder on its head and one nostril contains a membrane that he can inflate to show off to other Hooded Seals.
I find it hard to think of this as anything other than nature’s attempt at making slightly disgusting balloon animals.
Well done to everyone who worked it out – I have a couple of fun guest mystery objects for you next week!
