The American bullfrog (Lithobates catesbeianus), often simply known as the bullfrog in Canada and the United States, is a large true frog native to eastern North America. It typically inhabits large permanent water bodies such as swamps , ponds , and lakes .
The state of Michigan, and its location in the United States. Twenty-six amphibian species are found in Michigan, one of the fifty United States. These species include twelve species of frog, twelve species of salamander and two species of toad, all members of the class Amphibia.
They are small frogs, growing to 0.6 inches (1.5 cm) in length on average. Blanchard's cricket frogs hibernate during the cold months, beginning in late October, and emerging from hibernation in late March or early April. Breeding occurs from mid-May to mid-July. Females lay small clusters or single eggs. Tadpoles emerge in late summer ...
This makes the species even more unique, as PLOS One said, because other frogs that skip the egg step typically give birth to froglets, or baby frogs, but these frogs still give birth to tadpoles.
A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians, such as a lateral line, gills and swimming tails.
The African bullfrog is an exotic pet in many countries around the world. Animals sold are generally bred in captivity. Pet African bullfrogs may live for 35 years in captivity. [5] As pets, African bullfrogs are considered to be easygoing and low-maintenance in terms of their care. [21] It is considered a delicacy in Namibia. [22]
The bullfrogs frequently kill and eat residents' fish and chicks, both of which are important to the islanders. While Indian law prohibits their killing, it is still done, both out of desire to rid the islands of the species and for food (H. tigerinus is a very cheap source of protein). Despite these efforts, the frogs' spread continues. [9]
As tadpoles, the squirrel tree frog is preyed upon by dragonfly nymphs, giant water bugs, predatory fish and newts. [2] [3] Once the tadpoles metamorphose, the predators of the frogs change to small mammals, other frogs, snakes, birds. [2] To reduce the danger of being eaten as tadpoles, they use dense vegetation as cover. [4]
