The ocean floor near Los Angeles is the largest graveyard for whales yet seen. Surveys have found evidence of more than 60 whale skeletons there. Scientists have used sonar and video cameras to map a couple of ocean basins that are centered about 15 miles offshore.
Researchers have been studying the region for years, in part because it was a dumping ground for DDT and related chemicals. Scientists are seeing how that affects life in the ocean, and how it might impact human health.
If you thought dating other humans was complicated, wait until you hear about the complex courtship behaviors of wild leopard seals. These apex predators are the second largest Antarctic seal species after southern elephant seals. At 8 to 11 feet long and weighing up to 1,300 pounds, their only natural predators are orcas. These ice-loving pinnipeds are notoriously difficult to study, but a team of researchers led by a Baylor University biologist managed to observe a two-hour courtship interaction between a male and female in Laguna San Rafael, Chile.
