 | | Blubber, defined as the adipose layer in the hypodermis, plays many important roles: it insulates the body, serves as a depot for stored energy, sculpts the external surface of the body into a hydrodynamic shape, adjusts buoyancy, and aids in locomotion. |
 | | Comparison of the blubber thickness distribution of robust porpoises killed randomly in commercial fishing operations with a sample of animals that died of terminal starvation and washed up on beaches provides an opportunity to determine how blubber might be used as an energy source in an extreme situation. |
 | | Harbour porpoise blubber is not a homogeneous tissue: there is a significant difference in the fatty acid composition between the inner (next to the muscle) and outer (adjacent to the skin) blubber. |
