The female strawberry poison-dart frog (Oophaga pumilio) lays her eggs on the forest floor. The male frog guards them from predation and carries water in his cloaca to keep them moist. When they hatch, the female moves the tadpoles on her back to a water-holding bromeliad or other similar water body, depositing just one in each location.
Their coloration ranges between white and brown and changes in response to temperature (see adaptations below). They tend to turn white when they die. [3] The grey foam-nest tree frog typically has a snout length of 50–80 mm. Males have a snout-vent length of 43–75 mm, while females have a 60–90 mm snout-vent length. [2]
Darwin's frog (Rhinoderma darwinii), also called the Southern Darwin's frog, [2] is a species of frog of the family Rhinodermatidae. It was discovered by Charles Darwin during his voyage on HMS Beagle. [3] on a trip to Chile. In 1841, French zoologist André Marie Constant Duméril and his assistant Gabriel Bibron described
Female frogs lay their eggs at the side of wells or above the water line, exhibiting a form of terrestrial oviposition–another indicator of high parental investment. [7] The climbing mantella is the only member of the genus Mantella where parent frogs care for oophagous tadpoles.
Some glass frogs show parental care: in many species, glass frog females brood their eggs during the night the eggs are fertilized, which improves the survival of the eggs, while in almost a third of species, glass frog males stay on guard for much longer periods. After they hatch, the tadpoles fall into the waters below. [15]
Frogspawn are jelly-like frog eggs that appear at the edges of ponds and streams, and normally it is a sign spring has arrived, according to the National History Museum.
The wood frog has evolved traits that prevent their cells from being damaged when frozen and thawed out. The wood frog has developed various adaptations that allow it to effectively combat prolonged ischemia/anoxia and extreme cellular dehydration. One crucial mechanism utilized by the wood frog is the accumulation of high amounts of glucose ...
