Marine mammals, which include seals, whales, dolphins, porpoises, manatees, dugongs, marine otters, walruses, and polar bears, form a diverse group of 129 species that rely on the ocean for their existence. They do not represent a distinct biological grouping, but rather are unified by their reliance on the aquatic environment for feeding. The level of dependence on the aquatic environment for existence varies considerably with species. For example, dolphins and whales are completely dependent on the marine environment for all stages of their life, whereas seals feed in the ocean, but breed on land.
Marine mammals can be subdivided into four recognized groups; cetaceans (whales, dolphins, and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), and fissipeds, which are the group of carnivores with separate digits (the polar bear, and two species of otter). Both cetaceans and sirenians are fully aquatic and therefore are obligate ocean dwellers. Pinnipeds are semiaquatic; they spend the majority of their time in the water, but need to return to land for important activities such as mating, breeding and molting. In contrast, both otters and the polar bear are much less adapted to aquatic living. While the number of marine mammals is small compared to those found on land, their total biomass is large. They play important roles in maintaining marine ecosystems, especially through regulation of prey populations. These two factors make them an integral component of the marine environment. This is of particular concern considering 23% of marine mammal species are currently threatened.

In October 2013, the DoD HMA and the Department of State's Office of Weapons Removal and Abatement, which provides conventional weapon destruction assistance, including landmine clearance programs worldwide, invited the US Navy marine mammal program mine hunting dolphins to Croatia to search for remnants of the 20th century wars which had been fought in the area around Dubrovnik. The DoD HMA Program and the State Department's Office of Weapons Removal and Abatement also contributed some funding for this deployment. This 10 min. video details operation "Dolphin 2013" and gives an overview of U.S. Navy Marine Mammal Program mine counter-measures work.

The Science of Picky Eaters - 02:00 What makes a dish taste good to some people and terrible to others? Why do many people, particularly many kids, find broccoli and spinach unbearably bitter? Neil deGrasse Tyson, whose mother says he was always a good eater, sets out to investigate the science behind our sense of taste. It turns out that genetics largely determine our taste, and specific genes may provide new excuses for picky eaters.
