Humpback Whale Calls

1 August 2012: A Humpback whale's non-song signals were recorded by on Ocean Sonics icListen high frequency hydrophone deployed in Folger Passage at a depth of 95m. Humpback whales can grow up to 16 m long and weigh an average of 36,000 kg. They have unusually long pectoral fins that are nearly 1/3 of their body length, giving them their scientific name Megaptera novaeangliae, meaning "big wing of New England." Despite their large size, they are known to be acrobatic, occasionally breaching and slapping their fins on the water's surface. They live in most oceans, undergoing yearly migrations of up to 8,300 km from their breeding and calving areas in tropical and subtropical waters to the nutrient-rich polar waters where they spend their summers feeding. They do not eat in the winter, and live off their fat stores during the breeding and calving season. All humpback whales vocalize, making a variety of sounds called wops, grunts, upsweeps, downsweeps, whistles, etc. Male humpback whales combine their vocalizations into complex patterns that form songs up to half an hour long, which they repeat for hours or days. All humpback whales in a particular ocean region sing the same song, which changes from year to year. Humpback whales have a lifespan of 45 to 50 years. Humans and possibly orcas are their only predators. Threats to humpback whales include ship collisions, entanglement in fishing gear and noise pollution. https://www.oceannetworks.ca/ Follow ONC on social media: Twitter:   / ocean_networks   Instagram:   / ocean_networks   Facebook:   / oceannetworkscanada
