As a result, these animals are able to thrive in environments with cold or highly variable thermal conditions, and in some nocturnal habitats unavailable to ectothermic vertebrates.
-
Reptiles have generally been described as sluggish, cold-blooded ectotherms.
-
Many ectothermic species demonstrate behavioral thermoregulation following feeding in an attempt to increase body temperature, thus increasing temperature-dependent rate processes associated with catabolism.
-
Dinosaurs were mostly inertial homeotherms; they were ectothermic but maintained a constant body temperature by growing large.
-
An organism, such as a fish or reptile, having a body temperature that varies with the temperature of its surroundings; an ectotherm.
-
Similarly, some modern ectotherms, chameleons for example, have an erect posture.
-
With regard to the distance traveled before exhaustion, intermittent locomotion can have greater consequences for ectotherms than endotherms.
-
For example, one might think that skeletal growth rates would be higher for an endothermic animal than for an ectothermic, or cold-blooded, one.
-
The 10-fold seasonal differences in FMR were reasonable for an ectothermic poikilotherm.
-
That's why several zoos are participating in a sort of sperm bank for snot otters, says Dale McGinnity, ectotherm curator for the Nashville Zoo.

-
Ecological studies suggest that today's endotherms (mammals and birds) generally outcompete ectotherms in their area.
-
A lack of metabolic data has made this association more difficult to assess in most ectothermic vertebrates, and little is known of any possible relationship between genome size and metabolic rate in fishes and reptiles.
-
Thus, perhaps the commonly asked question whether dinosaurs were ectotherms or endotherms is inappropriate, and it is more constructive to ask which dinosaurs were likely to have been endothermic and which ones ectothermic.
-
It is conceivable, therefore, that during the evolution of endothermy there existed a continuum of physiological constitutions that were intermediate to those known from typical ectotherms and endotherms today.
-
Other eurythermal ectothermic marine organisms have been examined for their HSP responses.
-
Since it is unlikely that a large warm-blooded animal will loose this metabolic characteristic and become cold-blooded, there is a solid case that Triassic thecodonts were also ectotherms.
-
Three-segmented ectothermic quadropod, filiform antennae, mandibulate mouthparts, tegmina and hindwings, seemingly asocial.

For example, one might think that skeletal growth rates would be higher for an endothermic animal than for an ectothermic, or cold-blooded, one.
-
Gigantothermy • Sometimes called ectothermic homeothermy) • Large, bulky ectothermic animals are more easily able to maintain a constant, relatively high body temperature than smaller animals by virtue of their greater volume to surface area ratio.

-
Whereas an endotherm expends a tremendous amount of energy just to maintain a constant body temperature, a cold ectotherm can pass months at a time requiring little food or oxygen.
Amphibian
-
Endotherms differ from an ectotherm because they typically have core temperatures above that of the surrounding environment, whereas the core temperatures of ectotherms depend on external sources of heat – primarily from solar radiation.
Endotherm
-
The papers cover a substantial range of physiological systems and numerous types of organisms, including ectotherms and endotherms, vertebrates, insects, plants, and bacteria.
-
Because the wingbeat frequency and power output of small ectotherms, like Drosophila, declines with decreasing temperature, the total lift generated by flies exposed to cold temperatures declines substantially.
-
The temperature at which the eggs of ectothermic vertebrates incubate can influence several phenotypic traits of offspring.
