Identify this property, characteristic of fish and amphibians, which requires certain animals to absorb heat from their surroundings in order to regulate body temperature.
Scientists debate whether the extinct goat Myotragus balearicus had this property, which is often associated with lammellar-zonal bone. Animals with this property generally have Q-ten values greater than one, and their energy ex- penditure is calculated in terms of standard metabolic rate. Many animals of this type generate cryoprotectants in cold regions, and pupfish are an unusual example of this property because they use desert hotsprings to maintain a consis- tent environment. Inward blood circulation in marine iguanas and basking in alligators are two adaptations to this property seen in reptiles.
