Blue whales and fin whales — the largest in the ocean — make noises at very low frequencies which means the sound can travel for many kilometres. Each organism has a different acoustic signature, and she can often figure out what sort of creature the waves are bouncing off of. Whitehead, who was a co-author of the paper, cautions that a full understanding of codas is still a long way off. Vocal clans can be huge—thousands of individuals spread out over thousands of miles of ocean. Native to subtropical waters, they were caught in by fishermen as far north as Alaska. Even so, he believes the differences represent cultural variants among the clans.

While killer whales have been recorded learning and mimicking the sounds of neighboring bottlenose dolphins , the researchers were curious to see if these same skills could be applied to both human and other environmental noises. Because Carlos is not a squid, he had nothing to fear. I will also present what may also be sperm whale sounds in some recordings made during previous days — by the Ocean Networks Canada hydrophones located just over the border in the Strait of Georgia off the mouth of the Fraser River.

Indirectly, the oil could kill their food fish and plankton. Have a listen to the Vancouver Island sperm whale, from the hydrophones of the incredible OrcaLab research station:. The squid, it turns out, are following creatures whose behavior was first noted during World War II, when naval sonar operators observed that the seafloor had the unexpected and somewhat alarming tendency to rise toward the surface at night and sink again during the day. That allows them to figure out how large the cavity is. Facebook Twitter Email Print.
In many ways, the sperm whale can claim the title "lord of the sea". How the survive the enormous pressure of these dives, even how they catch their prey, remain mysteries despite our long acquaintance with these whales. They are so difficult to study in the depths of the sea that, in many respects, sperm whales might live on some other planet and be no less known than they now are. They are known to dive as deep as 3, feet in search of squid to eat and can hold their breath for up to 90 minutes on such dives. I am here because scientists have started to figure out just what it is a sperm whale does in the deep: And in the Sea of Cortez, the focus of its attention is Dosidicus gigas , the jumbo squid.
