Once the predator is removed, the growth rate of the tadpole returns to, or even exceeds, baseline. This influence of predator threat is only significant during early tadpole development. [28] One of the common frog's most pervasive predators is the red-eared slider (Trachemys scripta elegans), which is a very invasive species of turtle.
Adult frogs are themselves attacked by many predators. The northern leopard frog (Rana pipiens) is eaten by herons, hawks, fish, large salamanders, snakes, raccoons, skunks, mink, bullfrogs, and other animals. [168] A trophic pyramid showing frogs as primary predators. Frogs are primary predators and an important part of the food web.
A main predator on the glass frog in its tadpole stage are "frog flies", which lay their eggs within the frog eggs; after hatching the maggots feed on the embryos of the glass frogs. [8] Glass frog behaviors to avoid predation vary from species to species as well as circumstances.
Nonetheless, the captive-bred frogs retain the ability to accumulate alkaloids when they are once again provided an alkaloidal diet. [25] Despite the toxins used by some poison dart frogs, some predators have developed the ability to withstand them. One is the snake Erythrolamprus epinephalus, which has developed immunity to the poison. [26]
The golden poison frog is one of the most poisonous animals on the planet; these frogs produce deadly alkaloid batrachotoxins in their skin glands as a defense against predators. [ 16 ] [ 17 ] To become poisoned a predator generally must attempt to consume the frog, although this species is so toxic that even touching an individual frog can be ...
They are immune to the poison and they secrete it through their skin as a defense mechanism against predators. This poison is so efficient, the native people of the South American Amazon rainforest use the frogs' toxins on their weapons to kill their prey, giving the frogs their nickname the "poison dart frog".
The African clawed frog (Xenopus laevis), also known as simply xenopus, African clawed toad, African claw-toed frog or the platanna) is a species of African aquatic frog of the family Pipidae. Its name is derived from the short black claws on its feet.
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.
