Mar 5, 2024 · The temperature of ectothermic or cold-blooded animals depends on their environment. Most reptiles, amphibians, fish, and invertebrates are ectothermic. Endothermic or warm-blooded animals regulate their body temperature using mechanical and metabolic processes (e.g., shivering, perspiration, exothermic chemical reactions).

Scientific Family: Testudines Turtlesand 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. They range in size and appearance, but they are all cold-blooded. There are actually some turtle species that let the environmental ...
Scientific Name: Apis mellifera Honey bees are interesting insects that provide pollinationfor a wide array of plants. Like other insects, honey bees are cold-blooded. With that said, however, the American Bee Journal states that, while a single bee itself is cold-blooded, the entire hive can be considered a warm-blooded structure. This is due to t...
Scientific Suborder: Serpentes spp. Snakes are found just about everywhere on Earth, with the exception of New Zealand, Ireland, Iceland, Greenland, and Antarctica. There are over 3,000 species, with the boa and python families being the largest, and all of them are cold-blooded. These fascinating creatures strike fear in the hearts of many, and th...
Scientific Name: Crocodylinae Crocodiles are large, fierce, and aggressive. In the wild, they can prey on zebras, elephants, and other large animals. In fact, the largest living reptile is the saltwater crocodile, which can reach lengths of up to 20 feet with a weight of almost 3,000 pounds. In order to warm themselves, these cold-blooded animals h...
Scientific Name: Alligator Alligators are often confused with crocodiles due to their similar appearance and nature. While they are both cold-blooded, alligators are generally smaller in size than crocodiles, with max sizes of about 14 feet long and up to 1,000 pounds. Their snouts are also rounded and broad, while crocodiles’ snouts are pointed an...
Scientific Order: Anura As with crocodiles and alligators, frogs and toads are often confused with one another. In this case, both are amphibians which means they reproduce in the water and are cold-blooded, with similar characteristics. In fact, all toads are frogs, but not all frogs are toads. Confusing isn’t it? While they both live near marshes...
Scientific Name: Caudata Like frogs and toads, salamanders are amphibians(and thus cold-blooded). However, salamanders have tails and teeth, which are two things frogs and toads are lacking. There are 600 recognized species of salamanders, and most grow to about 6 inches long. The Japanese Giant Salamander, however, can grow up to 6 feet long and w...
Scientific Name: Varanus komodoensis A member of the monitor lizard family, komodo dragons are the largest species of lizards alive today. They measure about 10 feet long and weigh around 300 pounds. They are found on Komodo Island, as well as on nearby islands in Indonesia. These lizards have a venomous bite that releases toxins into their prey. T...
Scientific Name: Heterocephalus glaber The naked mole rat doesn’t just have a funny name, this unusual looking creature is one of the rare mammals who are cold-blooded. As its name suggests, the naked mole rat is hairless with pink or grayish, wrinkly skin. They measure about 3 inches long and weigh in at about 1 ounce to 2 ounces. Naked mole ratsl...
Scientific Name: Anisoptera Because they are cold-blooded, dragonflies bask in the sun’s rays to increase their internal body temperature. However, these crafty creatures are not without their own tricks to help control their internal temperature without the help of the sun. If the sun isn’t shinning, dragonflies can shiver, also known as wing whir...

Nov 28, 2023 · Warm-blooded animals — today’s mammals and birds — maintain their body temperature without an external heat source like the sun. They use their own metabolism to regulate their body heat. Meanwhile, cold-blooded animals need an outside heat source to get warm. Today, no mammal is cold-blooded, but it was not always so.
Jun 9, 2023 · Cold-blooded animals can be either terrestrial or aquatic. All reptiles, amphibians, fish, and insects possess this trait, such as alligators, turtles, snakes, lizards, crocodiles, bees, frogs, toads, and sharks.

Aug 3, 2023 · The proteins in warm-blooded animals are not temperature-specific. The genome in some cold-blooded animals might be more complex. The genome in most warm-blooded animals has simpler complexity. Excessive fat causes overheating of the bodies of cold-blooded animals and might even lead to death.
6.1 Warm-blooded vs cold-blooded. The processes of regulating the internal temperature in mammals contrast sharply with that of other animals, except birds, and a few others. Heat energy liberated during metabolism enables mammals to maintain a stable body temperature and occupy habitats where the external temperature may vary over a large ...
