National Geographic has captured the hooded seal in his element. They have a flap of skin on their heads that can be inflated when they get agitated or excited. The hood is an enlargement of the nasal cavity, and only the males have hoods, according to softschools.com.
The seal uses this as an intimidation tactic. Size does matter during mating season, the males with the larger hoods will have a better chance of mating. Hooded seals live in the North Atlantic and Arctic Oceans, they can be seen lying on ice blocks. They can also dive deep underwater and stay submerged for long periods.
Sadly, these amazing animals are listed as a “vulnerable” species by the International Union for Conservation of Nature (IUCN). The greatest threat to these animals is humans, who hunt them for their pelts.
