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.

[160] [161] A few species also eat plant matter; the tree frog Xenohyla truncata is partly herbivorous, its diet including a large proportion of fruit, floral structures and nectar. [ 162 ] [ 163 ] Leptodactylus mystaceus has been found to eat plants, [ 164 ] [ 165 ] and folivory occurs in Euphlyctis hexadactylus , with plants constituting 79.5 ...

The tailed frogs are two species of frogs. The species are part of the genus Ascaphus, the only taxon in the family Ascaphidae / æ ˈ s k æ f ɪ d iː /. The "tail" in the name is actually an extension of the male cloaca. The tail is one of two distinctive anatomical features adapting the species to life in fast-flowing streams.
The pickerel frog's poisonous secretions cannot stop all creatures; green frogs, bull frogs, northern water snakes, eastern ribbon snakes, and common garter snakes are their usual predators. [22] When threatened, pickerel frogs will jump into the water and dive to the bottom to escape predators like birds and snakes.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
Lithobates clamitans [5] or Rana clamitans, [2] [6] [7] commonly known as the green frog, is a species of frog native to eastern North America. The two subspecies are the bronze frog and the northern green frog. These frogs, as described by their name, typically have varying degrees of green heads.
