has a body length of nearly 300 mm (12 inches). Many frogs and toads have smooth moistskins. Toads of the genusBufoare familiar as “warty” amphibians, the skin being highly glandular and covered with tubercles (small, round nodules). Frogs of many other families have rough tubercular ...
Active foragers,includingseveral species of bufonidtoads and den- drobatid frogs eat these arthropods almost exclusively. In contrast, many Eleutherodactylusspecies thatare sit-and-waiptredatorseat mostlyorthopterans and coleopterans(Toft 1980, 1981). This association betweenforagingmode and prey ...

These three orders of livingamphibiansare thought to derive from a single radiation of ancient amphibians, and although strikingly different in body form, they are probably the closest relatives to one ...

amphibians include ectothermic tetrapods such as frogs toads and salamanders. the distinguishing feature that separates amphibians from reptiles is their breeding behaviour. most amphibians need a body of water to breed as their eggs are shell-less. furthermore, they undergo metamorphosis where the ...
Other large animals that inhabit areas of the Rockies are Bighorn sheep, mountain goats, varieties of deer (including caribou), and elk. Wild horses may inhabit adjacent plain areas. Small animals include varieties of chipmunks and squirrels, marmots, frogs, toads, salamanders, and snakes. ...
Amphibians are cold-blooded vertebrates belonging to the classAmphibia, including all frogs, toads, salamanders, newts, and caecilians. They spend part of their lives in water and the rest mostly on land. In fact, the word ‘amphibian’ comes from a Greek word meaning ‘both lives’, referrin...
they go through four stages - egg, larva, pupa, and adult. Every stage has different goals to achieve like caterpillars need to eat a lot and adults need to reproduce. The life cycle of the butterfly may depend on the type of butterfly, it might take from a month to a whole year....
Part B: Important Evolutionary Advances Jaws in Fishes Fish are considered to be the most primitive living vertebrate. The first fishes to be found in abundance in the fossil record were jawless. These are limited to eating small particles of food by filter-feeding and vacuum suction. The evol...
A single-electron transistor (SET) is an electrical device that takes advantage of a strange quantum phenomenon called tunneling to transport single electrons across a thin insulator. The device serves as an on/off switch on the tiniest scale and could play an important role in quantum computing...
