Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).
According to the American Marketing Association, consumer behaviour can be defined as "the dynamic interaction of affect and cognition, behaviour, and environmental events by which human beings conduct the exchange aspects of their lives." As a field of study, consumer behaviour is an applied social science. Consumer behaviour analysis is the ...
Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia . They inhabit a wide variety of habitats , with most species living within terrestrial , fossorial , arboreal or freshwater aquatic ecosystems .
This classification is the one most commonly encountered in school textbooks and popular works. While orderly and easy to use, it has come under critique from cladistics. The earliest tetrapods are grouped under class Amphibia, although several of the groups are more closely related to amniotes than to modern day amphibians. Traditionally ...
Caecilians have small or absent eyes, with only a single known class of photoreceptors, and their vision is limited to dark-light perception. [17] [18] Unlike other modern amphibians (frogs and salamanders) the skull is compact and solid, with few large openings between plate-like cranial bones. The snout is pointed and bullet-shaped, used to ...
They feed readily on any animal they can fit in their mouths, which can result in cannibalistic behavior if frogs housed together have a significant size difference. [24] Their toxic mucus can burn the eyes and trigger an allergic (or asthmatic) reaction; as a result, this species is not an ideal pet species, especially for children.
See the consumer behaviour article for an overview. Consumer behaviour is a multidisciplinary field which is integral to industrial psychology and aspects of household economy studied in microeconomics. Consumer behaviour also means the actions shown by consumers while making decision to select household and consumer items.
It is crucial for most amphibians to maintain a high level of genetic variation through large and more diverse environments. Education of local people to protect amphibians is crucial, along with legislation for local protection and limiting the use of toxic chemicals, including some fertilizers and pesticides in sensitive amphibian areas.
