Weddell Seal: Vocalization in Sheet Music

Weddell Seal (Leptonychotes weddellii) are named after the Weddell sea in Antarctica, which in turn takes its name from James Weddell, a British explorer. These animals are extremely good divers. Although shallow dives of 20 minutes are typical, they have been observed to dive to about 700 meters for up to 82 minutes. Like other marine mammals, Weddell Seals have evolved to use sound and hearing as their primary means of communication and sensing their surroundings. They produce a wide range of vocalization, including trills, whistles, low frequency buzzes, and chirps. Their frequency range covers 80 Hz to 24 kHz (as a reference, we can only hear up to 20 kHz) and can reach up to 193 dB re 1 µ Pa. Some of their noises are so loud they can be felt through the ice. Individual Weddell seals can each produce their own unique song (repeating a series of notes and changing it gradually), but apparently this behavior is uncommon.
