The hooded seal gets its name from an inflatable bladder on the head of the male. The bladder hangs over the eyes and the lips when deflated.
They can inflate the bladder before diving underwater. They can then inflate and deflate the bladder as they are swimming. The inflated sac can be used by the hooded seal when swimming to ward off other species when it feels threatened.
Males have a membrane that comes out of the left nostril that produces sounds which they use to attract a mate, but mainly for signaling acoustically.
The inflatable bladder is used for accoustic signaling, threatening other species when competing for food. The bladder also communicates information about their status and health to other members of the species.
The nostril membrane produces different sounds when shaken, depending if underwater or on land. These signals can be used for sexual purposes to attract a mate, but are used mainly for acoustic situations and signalling.
