Food preferences were different among the different weight groups of frogs, possibly correlating to different stages of development. Frogs weighing less than 400 g (14 oz) consumed annelids, arachnids, myriapods, insects, crustaceans, gastropods, and reptiles. Frogs weighing more than 1,000 g (35 oz) consumed arachnids, myriapods, insects ...
Rheobatrachus, whose members are known as the gastric-brooding frogs or platypus frogs, is a genus of extinct ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, the southern and northern gastric-brooding frogs, both of which became extinct in the mid-1980s.
Moor frogs are renowned for their ability to tolerate freezing temperatures because most frog species live in hot and humid tropical environments. Many frogs that do live in cold climates will attempt to overwinter in bodies of water because ambient temperatures are moderated by water. In these cases, temperatures only reach a few degrees below ...
Frogs are extremely efficient at converting what they eat into body mass. They are an important food source for predators and part of the food web dynamics of many of the world's ecosystems. The skin is semi-permeable, making them susceptible to dehydration, so they either live in moist places or have special adaptations to deal with dry habitats.
Unique to the tailed frogs is the ability to secrete a series of antimicrobial peptides called ascaphins. These peptides share minimal genetic characteristics with other peptides secreted by frogs, yet show some similarities with antibacterial peptides found in African scorpions Pandinus imperator and Opistophthalmus carinatus.
Pig frogs are opportunistic feeders and will eat a wide variety of prey, including insects, worms, and small vertebrates. Their primary diet is crawfish, but like most bullfrogs, they will consume almost anything they can swallow, including insects, fish, and other frogs. They are known to feed on beetles, dragonflies, crayfish, and other ...
Two burnsi morphs, a green morph, and a brown morph of the northern leopard frog Brown morph northern leopard frog in a wood chip pile in Iowa. The northern leopard frog has several different color variations, with the most common two being the green and the brown morphs, with another morph known as the burnsi morph. Individuals with the burnsi morph coloration lack spots on their backs, but ...
Like other creatures, these frogs hibernate in the winter, usually underground but sometimes in other water-resistant locations, like logs or other forms of wood. [2] Almost immediately after winter, these frogs leave their usual habitats for calm freshwater where they can lay their eggs without having to worry about fishes disturbing them ...
