An ectotherm (from Ancient Greek ἐκτός (ektós) ' outside ' and θερμός (thermós) ' heat '), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. [2]
The circulatory system of a snake is basically like those of any other vertebrae. However, snakes do not regulate internally the temperature of their blood. Called cold-blooded, snakes actually have blood that is responsive to the varying temperature of the immediate environment. Snakes can regulate blood temperature by moving.
Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals ) maintain a stable body temperature by regulating metabolic processes.
A boa constrictor in the U.K. gave birth to 14 babies — without a mate. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.” It tends to occur in ...
In the fall, when the days get shorter and temperatures drop, snakes generally begin to pare back their activity to daylight hours only, given they are ectothermic (cold-blooded) creatures that ...
They found that snakes experienced a burst of innovation early in their history and have evolved at a rate perhaps three to five times faster than their lizard cousins.
Cold-blooded is an informal term for one or more of a group of characteristics that determine an animal's thermophysiology. These include: Ectothermy, controlling body temperature through external processes, such as by basking in the sun; Poikilothermy, the ability of an organism to function over a wide internal temperature range
