Mar 5, 2024 · The temperature of cold blooded or ectothermic animals varies with the environment, while warm blooded or endothermic animals maintain a relatively stable temperature. The animal kingdom falls into two categories based on how species regulate their body temperature: ectothermic and endothermic. This distinction plays a crucial role in how ...
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 are of relatively small or of quite negligible importance in controlling body temperature. [2] Such organisms ( frogs, for ...
fish. animal. amphibian. invertebrate. ectotherm, any so-called cold-blooded animal —that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates. The body temperature of an aquatic ectotherm is ...

Warm-Blooded or Cold-Blooded? The most important adaptation is how animals regulate their body temperature. Animals can be either warm-blooded or cold-blooded. Warm-blooded animals, which are mostly birds and mammals, need to maintain a relatively constant body temperature or they would suffer dire consequences.

Sharks are fascinating creatures whose body temperature adapts to match the water they inhabit. One feature of sharks is their complex vascular network, which ensures oxygen is distributed efficiently throughout their bodies. Interestingly, this circulatory system also causes their bodies to heat up to the temperature of the surrounding water and a...
Frogs are experts at regulating their body temperature through a combination of sunlight, water, and shade. During high temperatures, frogs rely on moisture and humidity to survive, and when the heat is too much, they instinctively cool off in water. In cooler weather, some frogs enter periods of dormancy, hibernating below ice or deep in mud. Duri...
Bee antennae possess incredible sensitivity in detecting temperature drops as low as 0.25°C. To maintain warmth, hives and be built to trap heat, and insulation is provided by the likes of tree trunks or layers of honeycomb. The concentrated warmth from the bees themselves keeps the hive's interior temperature ready for flight, regardless of the te...
Sea turtles are reptiles that rely on water to maintain their body temperature. They thrive at an optimal internal temperature between 25 and 27 Celsius, which is notably high given their low metabolic rate. Their moderate metabolism renders them vulnerable to frigid ocean temperatures; should ocean temps dip below 10 degrees Celsius, their bodies ...
Other organisms, such as the Dinoflagellates, a type of protist, also present cold-blooded features in their physiology. The most remarkable example is the Tardigrades or "water bears," which can survive high temperatures and intense radiation due to specific physiological adaptations. As an additional feature peculiar to this group, they

Cold and heat adaptations in humans. Cold and heat adaptations in humans are a part of the broad adaptability of Homo sapiens. Adaptations in humans can be physiological, genetic, or cultural, which allow people to live in a wide variety of climates. There has been a great deal of research done on developmental adjustment, acclimatization, and ...
