    The shape and number of scales on the head, back and belly are characteristic to family, genus and species. Scales have a nomenclature analogous to the position on the body.

  8. Metabolic theory of ecology - Wikipedia

    en.wikipedia.org/wiki/Metabolic_theory_of_ecology

    Small animals tend to grow fast, breed early, and die young. [27] According to MTE, these patterns in life history traits are constrained by metabolism. [28] An organism's metabolic rate determines its rate of food consumption, which in turn determines its rate of growth. This increased growth rate produces trade-offs that accelerate senescence.
