Michele Charlton - June 7, Taylor Hersh can trace her fascination with marine animals back to three things she encountered in sixth grade: a person, a book, and a photo. The person was a classmate who wanted to be a marine biologist. Hersh grew up in landlocked Pennsylvania, and had never thought of marine biology as a possible career option. The conviction of her fellow student was really inspiring to Taylor.
Marina Ventura’s Ocean Adventure
The view from a sperm whale’s nose | oceanbites
Thousands of people freedive as a sport, pushing themselves to depths as low as feet on a single breath. But I have no interest in that kind of often lethal, competitive agony. In the next two years, DareWin hopes to find out. The clicking has got louder. Through the diamond- clear water, I can just make out through my dive mask two black scuds in the distance; every few seconds the masses grow larger and larger, like ink blots on a napkin: two sperm whales, a mother the size of a school bus and her calf, the short bus. As the whales advance, I can feel the clicks penetrate my chest cavity. Sperm whales are the loudest animals on the planet.
Sperm whales Physeter catodon , or cachalots, are the largest of the toothed whales , with males up to 19 meters 62 feet long—more than five times the length of a large elephant —and females up to 12 meters 39 feet in length. They are easily recognized by their enormous square head and narrow lower jaw. As far as we can tell, Moby Dick was the only sperm whale that delivered a unique brand of karmic justice to one-legged sea captains bent on vengeance. Are they called sperm whales because their body shape is similar to that of male sex cells, or is there another reason? The head of the sperm whale contains an enormous fluid-filled organ which whalers called the case.
They possess the largest brain in the animal kingdom and spend much of their lives in the light-starved depths of the oceans hunting prey. The mighty sperm whales look nothing like any other whale. For a start, they each have an enormous square-shaped head which accounts for around a third of their body length. They have stumpy dorsal fins and two relatively small pectoral fins on either side of their wrinkle-covered bodies. Perhaps their most recognizable trait though is their jaw, containing up to 52 cone-shaped teeth in the lower half, weighing a kilo each!
