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.

Plant parts can be hard to digest, and, as they get closer to adulthood, juvenile iguanas eat faeces from adults to acquire the microflora necessary for their transition to a plant-based diet. Perhaps the most herbivorous species is the marine iguana which dives 15 m (49 ft) to forage for algae , kelp and other marine plants.
Their "harpoon" is venomous, which assists cone snail to paralyze or kill the prey before eating it. A number of vertebrate species also make use of solid projectiles. Among birds the hornbill uses projectile motion to eat food. The hornbill's beak typically only contacts at the tip, and it has a short tongue.
The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
Most lizard species and some snake species are insectivores. The remaining snake species, tuataras, and amphisbaenians, are carnivores. While some snake species are generalist, others eat a narrow range of prey - for example, Salvadora only eat lizards. [33] The remaining lizards are omnivores and can consume plants or insects. The broad ...
Researchers are increasingly aware that the bacteria in an animal’s gut play a huge role in everything from digestion to immunity.
Florida has a big lizard problem. Between lion fish and Burmese pythons, Florida has a lot of invasive species problems -- and the newest is massive Nile Monitor Lizards. Nile Monitor Lizards can ...
This lizard likely also eats flowering plants, but due to no rain falling during the study period, the animals were not observed consuming these plants. [17] Other herbivores, such as Ctenosaura pectinata (the spiny-tail iguana), have a mixed diet, with 52% of its diet composed of leaves, 35% flowers, and 2% of fruits. [ 6 ]
