Seals Sing 'Otherworldly' Songs Structured Like Nursery Rhymes

EASTERN ANTARCTICA, JUL 31 – Male leopard seals perform unique long songs with five notes to attract females and deter rivals, singing up to 13 hours during the spring breeding season, researchers said.

  • UNSW Sydney researchers published a study today showing male leopard seals in Antarctica sing underwater songs structured like human nursery rhymes.
  • This singing behavior occurs during the breeding season when males dive for two-minute cycles, performing solos for up to 13 hours daily to communicate across vast icy waters.
  • The study found all seals use the same set of five notes arranged uniquely to create personal sonic signatures, with song patterns exhibiting predictability similar to nursery rhymes.
  • Lead author Lucinda Chambers described the song patterns as conveying a combined message of identity and physical prowess, as if the singer is proudly demonstrating their size and strength through the duration and volume of their calls.
  • Researchers hope to revisit Antarctica using new tools to determine if leopard seal songs evolve over generations, aiming to improve understanding of animal communication and conservation efforts.
