whale: Characteristics and Behavior. Enter your search terms: Like other mammals, whales breathe air, are warm-blooded, and produce milk to feed their young. Their adaptations for aquatic life include a streamlined form, nearly hairless skin, and an insulating layer of blubber, which can be as thick as 28 in.

Mammals differ from other vertebrate animals in that their young are nourished with milk from special mammary glands of the mother. Mammals are distinguished by several other unique features. Hair is a typical mammalian feature, although in many whales it has disappeared except in the fetal stage.

They lack many common characteristics of animals such as a distinctive head or a mouth. They do not have eyes, ears, as well as other sense organs. They also do not possess major organs such as heart, stomach, muscles and even a nervous system.

Properties of Life. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Fortunately, biologists have developed a list of eight characteristics shared by all living things. Characteristics are traits or qualities. Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution.
