They are sympatric species. They occupy the same habitat but
do not interbreed probably because they are reproductively isolated or practice
behavioral isolation. To avoid extinction through interspecific competition, the
two species probably practice resource partitioning (differences in how species
use resources).
The Adipose tissue mainly works as storing energy into fat but it also works as an insulating layer that allows less heat to escape the body, as well as offer protection to major organs.
