May 30, 2019 · The term “cold-blooded” implies that these animals are in a never-ending struggle to stay warm. That really isn’t correct. Many species do like it hot, with some monitor lizards basking at temperatures of 120–150 F. I’d certainly call that some warm blood!
Mar 5, 2024 · Let’s explore the fascinating differences between ectothermic (cold-blooded) and endothermic (warm-blooded) animals, shedding light on their definitions, evolutionary history, mechanisms, and the pros and cons of each thermal strategy.

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

Aug 3, 2023 · Warm-blooded animals, like cold-blooded animals, have different mechanisms for thermoregulation; Endothermy and Homeothermy. Endothermy refers to the process by which various animals control their body temperature through internal means like burning fat, shivering, and panting.
- Turtles and Tortoises. Scientific Family: Testudines. Turtles and tortoises are a large group of reptiles that go back hundreds of millions of years. This group includes over 350 species found on land, as well as in both fresh and salt water.
- Honey Bees. Scientific Name: Apis mellifera. Honey bees are interesting insects that provide pollination for a wide array of plants. Like other insects, honey bees are cold-blooded.
- Snakes. Scientific Suborder: Serpentes spp. Snakes are found just about everywhere on Earth, with the exception of New Zealand, Ireland, Iceland, Greenland, and Antarctica.
- Crocodiles. Scientific Name: Crocodylinae. Crocodiles are large, fierce, and aggressive. In the wild, they can prey on zebras, elephants, and other large animals.
Feb 12, 2019 · Answer. Listener Jon emailed into the show. Chris Smith put his question to Jason Head from Cambridge Univeristy. Jason - Along with ‘living fossil’, ‘cold-blooded’ is my least favorite word combination. It is talking about metabolism and whether or not an organism maintains a very high, elevated, or constant metabolic rate; or a lower ...
Invertebrates (animals without backbones) and vertebrate fish, amphibians and reptiles, are said to be ‘cold-blooded’ because their body temperature changes with that of their surroundings. Low temperatures make it difficult for these creatures to remain active in winter – so what happens to them?
