Lipid-rich, collagen fiber-laced blubber comprises the hypodermis [2] and covers the whole body, except for parts of the appendages. It is strongly attached to the musculature and skeleton by highly organized, fan-shaped networks of tendons and ligaments, can comprise up to 50 per cent of the body mass of some marine mammals during some points in their lives, and can range from 5 cm (2 in ...
Marine mammal species richness: A) All species (n = 115), B) toothed whales (n = 69), C) baleen whales (n = 14), D) seals (n = 32), based on data from 1990 to 1999 [31] Marine mammals are widely distributed throughout the globe, but their distribution is patchy and coincides with the productivity of the oceans.

Erich Hoyt's work is "very much at the forefront of work on marine protected areas," [34] [driving] the shift from taxon-oriented protectionism (e.g., the Marine Mammal Protection Act) to more ecosystem-oriented approaches to conservation [and] marking...the growing relative importance of marine conservation vs. terrestrial conservation." [35]
All marine cone snails are venomous and can sting when handled. Their venom is a complex mixture of toxins, some fast-acting and others slower but deadlier. [44] Many painful stings have been reported, and a few fatalities. [43] Only a few larger species of cone snails are likely to be seriously dangerous to humans. [48]
The dugong (/ ˈ d (j) uː ɡ ɒ ŋ /; Dugong dugon) is a marine mammal.It is one of four living species of the order Sirenia, which also includes three species of manatees.It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century.
Marine mammal rehabilitation programs have been underway and regulated in the United States for more than 40 years. In 1973, injured and distressed manatees were rescued or aided in Florida. Eventually, the program was formalized into the Manatee Rescue, Rehabilitation, and Release Program managed by the US Fish and Wildlife Service.
Diving reflex in a human baby. The diving reflex, also known as the diving response and mammalian diving reflex, is a set of physiological responses to immersion that overrides the basic homeostatic reflexes, and is found in all air-breathing vertebrates studied to date.
Mammals, including deer and wild boar, are among the game animals most often hunted for sport and for food. Predatory mammals, most often dogs, are used to help catch game, and to retrieve shot birds. [25] [26] [27] Mammals are widely raced for sport, often combined with betting on the outcome, especially in horse racing and greyhound racing ...
