From: Leopard seal song patterns have similar predictability to nursery rhymes
Comparison of entropy estimates of the Eastern Antarctic male leopard seals with that of the humpback whales (Hawaiian53 and Australian56), bottlenose dolphins17,18 (‘bray’ call estimate indicated by *) and squirrel monkeys11 and entropy estimates of melodic contour of various music styles (songs by the Beatles43 various Classical42,45 Baroque42 and Romantic45,55 composers, and children’s nursery rhymes54). Entropy estimation methods are indicated by colour.
