Communication and Perception
Hooded seals are able to make vocalizations such as roars that can be heard easily on land. However, their most important form of communication is produced from the hood and septum. They are able to produce pulses ranging from 500 to 6 Hz, these sounds can be heard on land and in the water. They are often seen moving their inflated hood and nasal septum up and down, which can create sounds described as “pings” and “whooshes”. This method of communication can serve as male display for females but also serve as threats.
