Caecilians (/ s ɪ ˈ s ɪ l i ə n /; New Latin for 'blind ones') are a group of limbless, vermiform (worm-shaped) or serpentine (snake-shaped) amphibians with small or sometimes nonexistent eyes. They mostly live hidden in soil or in streambeds, and this cryptic lifestyle renders caecilians among the least familiar amphibians.
"Herp" is a vernacular term for non-avian reptiles and amphibians. It is derived from the archaic term "herpetile", with roots back to Linnaeus's classification of animals, in which he grouped reptiles and amphibians in the same class. There are over 6700 species of amphibians [9] and over 9000 species of reptiles. [10]

Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Feral and pet cats in Australia are estimated to kill around 650 million lizards and snakes per year, or about 225 reptiles per cat on average. Cats were found to be actively hunting and killing over 250 different species of reptiles in Australia, with 11 of which being considered endangered species. Cats consume so many lizards in Australia ...
The grass snake is widely distributed in mainland Europe, ranging from mid Scandinavia to southern Italy. It is also found in the Middle East and northwestern Africa. Grass snakes in Britain were thought to belong to the subspecies N. n. helvetica but have been reclassified as the barred grass snake Natrix helvetica.
They are not as tolerant of higher temperatures as other snake species and cannot inhabit areas that are too hot and dry, but can live in areas that are surprisingly cold, especially for a snake. Rubber boas also spend a large amount of time under shelter (rocks, logs, leaf litter , burrows, etc.) and thus must live in habitats that can provide ...
