               Crocodilians are very ancient species. The earliest crocodilian, meanwhile, evolved around 95 million years ago, in the Late Cretaceous period, coexisted  with dinosaurs. Their appearance always made me relating them to some low to the ground water-dwelling type dinosaurs.  After getting into the lizards' world, at macro scale, seem to me they are the dinosaurs survived from the mass extinction.  Could some survive to date but appear in a humble form - a great variety of lizards? Do you know that snakes are evolved from lizards?  Some snake species still have traces of not completely degraded legs. Most of the lizards have short and round tongues. Chameleons have elongated, extrudable tongues yet not forked. The lizards with a serpent-like forked tongue are the carnivorous ones of a larger size in family Varanidae (Monitors, goannas, Komodo dragon) and Teiidae (Tegus, whiptails, caiman lizards).

18. Asian water monitor. 2-2.5m 22.5kg, up to 3.2m, 45kg, related to Komodo dragon, often mistaken for them. Asian water monitor lizards do secrete venom, however, it is not lethally dangerous or fatal to humans while Komodo dragon bites can be fatal to humans without immediate treatment.

#25的表情尤其象恐龙。或者是没有人见过恐龙,所以恐龙的外观或表情是人通过蜥蜴推演出来的。 -移花接木- 给 移花接木 发送悄悄话 移花接木 的博客首页 (0 bytes) () 03/23/2024 postreply 17:57:02
