On the swells of the Sea of Cortez, everything looks like a whale. Lulled by disappointment, the rocking boat and general monotony, I drift into torpor. Then, less than half a mile away, a series of unmistakable spouts erupts, and bursts of exhalation carry across the water.
The contents of a whale's stomach reveal more than just its diet. Antonio via Flickr. Monday, April 21, - It will be a way of getting data on animals scientists know little about, and keeping track of environmental changes in the ocean.
A total of 27 ADB tags were deployed on sperm whales in the central Gulf of California, Mexico, during spring andof which 10 were recovered for data download. Tracking durations of all tags ranged from 0 to Recovered tags recorded a median of
Sperm whales are a genetic puzzle. The deep-diving, squid-eating giants that inspired Moby Dick are found in every ocean, where they can mate with partners from around the world; as such, they should be quite genetically diverse. Yet, their genetic diversity is actually very low, hinting that something killed a lot of them off in the past.
The inspiration for the white whale of Moby Dick, sperm whales have the largest heads, biggest brains, and make the loudest sound of any animal on Earth. Region: Arctic. Destinations: Lofoten, Greenland, Svalbard, Iceland.
The giant squid genus Architeuthis is a deep-ocean dwelling squid in the family Architeuthidae. The number of different giant squid species has been debated, but recent genetic research suggests that only one species exists. InJapanese researchers took the first images of a live giant squid in its natural habitat,  and in Julya live adult was first filmed in its natural habitat off Chichijima.
Malcolm Clarke was an international expert on two animals which remain among the most mysterious on the planet: the sperm whale and the giant squid. He spent most of his adult life pursuing these creatures, from the whaling grounds of the Antarctic,to the deep waters off the Azores — the remote archipelago where he lived latterly, within daily sight of his subjects. There, on cliffs of the island of Pico — a black lump of volcanic rock in the mid-Atlantic — Clarke built a remarkable museum in his garage dedicated to sperm whales and squid.
The giant cephalopods squids and octopuses of the deep sea have captured the imagination for centuries. But despite our fascination with these creatures, they are still enigmas, their behaviour illuminated only by the occasional lucky video or the presence of scars on animals they fight with. For many species, including the famous giant squidwe still know relatively little about what they eat and what position they occupy in their ecosystems.
