These results, together with the observation that plaque size on mammalian cell culture was on average larger following chicken passage, suggest that although SLEV is already highly adapted to its avian host, some further vertebrate-specific adaptation is certainly attainable.
Many are highly adapted to the eucalyptus forests.
They are highly adapted for conserving energy in cold weather.
Many species here are thus highly adapted, and seldom seen elsewhere in Britain.
In contrast, caecilians are limbless, wormlike, and highly adapted for a burrowing existence.
The most highly adapted of these are the flying lizards (Draco), a group of agamids from Southeast Asia.
However, they are more highly adapted to life in open plains, to grazing, and to cold, long winters.
The vast majority of species are terrestrial, but the pinnipeds are highly adapted to life in the water.
Snakes and other limbless vertebrates are highly adapted crawlers, using a variety of methods for gaining adhesion against the substrate.
Suckers, loaches, and most catfishes are typically benthic animals and thus are highly adapted to such an existence.
