Although dinosaurs have been reptiles, they’re believed to have traits of each chilly and heat blooded animals, and belonged to a transitional group with a posh metabolism, comparable to what’s seen in trendy birds.
3. Chilly-Blooded Animal Traits
In heat temperatures, cold-blooded animals are extra lively and may journey extra shortly. This happens as a result of warmth activated reactions present vitality to maneuver muscle tissue. Within the absence of warmth the animal turns into gradual and sluggish. So they’re normally inactive and relaxation when it’s chilly.

That is aestivation or summer season sleep, and differs from hibernation in that it lasts just for a day. Snails, frogs, salamanders, earthworms, snakes, crocodiles, desert tortoises are all identified to aestivate.
2. Advantages Of Ectothermy
Since they don’t generate their very own heat, the ratio of physique weight to floor space shouldn’t be as necessary as in warm-blooded animals. Subsequently, cold-blooded animals may be both small, as in bugs and lizards, or giant, corresponding to with crocodiles. They’re additionally free from parasites as their physique temperatures shouldn’t be fixed, so that they endure much less from sickness than heat blooded animals.
