Telmatobius culeus, commonly known as the Titicaca water frog or Lake Titicaca frog, [1] is a medium-large to very large and endangered species of frog in the family Telmatobiidae. [3] It is entirely aquatic and found only in the Lake Titicaca basin, including rivers that flow into it and smaller connected lakes like Arapa , Lagunillas and ...
The granular poison frog (Oophaga granulifera) is typical of a number of tree frogs in the poison dart frog family Dendrobatidae. Its eggs are laid on the forest floor and when they hatch, the tadpoles are carried one by one on the back of an adult to a suitable water-filled crevice such as the axil of a leaf or the rosette of a bromeliad .
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.
These studies revealed the bullfrog's diet to be unique among North American ranids in the inclusion of a large percentage of aquatic animals, such as fish, tadpoles, ram's horn snails, and dytiscid beetles, as well as the aquatic eggs of fish, frogs, insects, or salamanders. [47]
The movements of the frog do not stimulate the host tarantulas to attack and there is an unknown chemical present in the frog's skin that acts as a cue to the tarantulas that this species is not prey. [9] The spiders did attempt to catch and eat five species of frogs from the families Bufonidae, Hylidae, and Leptodactylidae. It is noted that ...
Pickerel frog egg masses are spherical and about the same size of a wood frog egg mass—roughly 5–10 cm in diameter—although pickerel frog egg masses contain more eggs, about 2000–3000. [4] Pickerel frog eggs are multicolored: they are dark brown on top and cream colored on the bottom. The egg masses adhere to woody or herbaceous ...
Eggs found in females measured up to 5.1 mm in diameter and had large yolk supplies. These large supplies are common among species that live entirely off yolk during their development. Most female frogs had around 40 ripe eggs, almost double that of the number of juveniles ever found in the stomach (21–26).
The spring peeper is a tan or brown frog with a dark cross on its dorsa (thus the Latin name crucifer, meaning cross-bearer [7]), though sometimes the marking may be indistinct. [ 8 ] [ 9 ] Dark lines can also be found between the eyes and in a crossband on the hindlimbs of P. crucifer . [ 10 ]
