Hooded Seal
Hooded Seal
The hooded seal has a couple of very odd features.Males have both an inflatable skull hood and nasal balloon. When aroused, angered or simply showing off, male hooded seals can inflate their sacs that are a foot or more in diameter. The bright red nasal balloon can be inflated through one or both nostrils. Unfortunately, due to global warming affecting the arctic environment, hooded seals are now considered to be endangered.
