Species detectives track unseen evolution
...ings go against received wisdom that the insect or reptile branches of the animal kingdom are more likely to harbour cryptic species, and that these are more likely to be found in the tropics than in temperate regions. Zoologists should therefore consider factoring in a degree of cryptic diversity as a rando...Researchers track snakes to study populations, behavior

The advantages of being a 'warm' reptile are that no energy has to be expended to produce metabolic heat to keep warm; in other words, if we were warm reptile-like ectotherms, we would save a lot of money on the grocery bill."
