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 ...
