An ectotherm (from the 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]
Hybrid incompatibility occurs when the offspring of two closely related species are not viable or suffer from infertility. Charles Darwin posited that hybrid incompatibility is not a product of natural selection, stating that the phenomenon is an outcome of the hybridizing species diverging, rather than something that is directly acted upon by selective pressures.

They may be super fluffy and adorable, but there are lots of things to consider before getting a rabbit. We often think of bunnies as being low-maintenance pets, but believe it or not, rabbits ...
Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. 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.
Allen's rule - Hare and its ears on the Earth [1]. Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, [2] [3] broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates.
Dr. MacMillan says: "Temperatures above 25C (77 F) are too hot for rabbits. They will start to struggle at these sorts of high temperatures, and you should take steps to keep your rabbit safe and ...
The reason for this is that Himalayans can only produce eumelanin under a certain temperature and they cannot produce pheomelanin at all. Kits will get their markings at the age they become more independent from their mother and littermates. If a nest gets too cold or a baby falls out, they will get dark bands on their fur.
Rabbits need unlimited access to grass and hay, so they shouldn't ever be left without food. However, if it's an emergency and there's no other choice, then they can go up to 12 hours without eating.
