Communication and Perception
The eyes of Leptonychotes weddellii are well developed for low light visibility. This is an adaptive feature of this creature which assists it in locating breathing holes in the ice (Stirling 1971). Vocalization occurs underwater for communication. Overlapped calls are longer than solitary calls, which constitute the varied repertoire of vocal communication in the Weddell seal (Terhume 1994).
