Topographical distribution of blubber in finless porpoises(Neophocaena asiaeorientalis sunameri): a result from adapting toliving in coastal waters

摘要

Background: Blubber has many functions, among which energy storage, thermoregulation,buoyancy, and hydrodynamic streamlining are the most frequently cited. Within and betweentaxa, variations in its structure and distribution likely reflect different adaptations ofa species to its life history requirements, environment, health, and function. Here, weuse ultrasound to describe the distribution of blubber in the finless porpoise( ) based on examinations of 34fresh cadavers recovered as accidental fisheries bycatch.
