In many frog species, such as the common tree frog (Polypedates leucomystax), females reply to males' calls, which acts to reinforce reproductive activity in a breeding colony. [93] Female frogs prefer males that produce sounds of greater intensity and lower frequency, attributes that stand out in a crowd.
A pair of clicking stream frogs (Strongylopus grayii) in amplexus Orange-thighed frogs (Litoria xanthomera) in amplexusAmplexus (Latin "embrace") is a type of mating behavior exhibited by some externally fertilizing species (chiefly amphibians and horseshoe crabs) in which a male grasps a female with his front legs as part of the mating process, and at the same time or with some time delay, he ...
In the frog Rhinoderma darwinii, the zygotes develop in the vocal sac. In the recently extinct frogs Rheobatrachus , zygotes developed in the stomach. Histotrophic viviparity: the zygotes develop in the female's oviducts , but find their nutriments from other tissues, whether skin or glandular tissue, oophagy or adelphophagy ( intra-uterine ...
Male Dendropsophus microcephalus calling. Sexual selection in amphibians involves sexual selection processes in amphibians, including frogs, salamanders and newts.Prolonged breeders, the majority of frog species, have breeding seasons at regular intervals where male-male competition occurs with males arriving at the waters edge first in large number and producing a wide range of vocalizations ...
Multimale amplexus, in which multiple males mate with a single female, is the predominant method of mating that the moor frog performs. [19] The sperm of male moor frogs compete in the female reproductive tract for fertilization of the female's egg. Female frogs do not appear to prefer males of a particular size. [19]
Male Rana temporaria calling in a garden pond in Jambes, Belgium. The common frog or grass frog (Rana temporaria), also known as the European common frog, European common brown frog, European grass frog, European Holarctic true frog, European pond frog or European brown frog, is a semi-aquatic amphibian of the family Ranidae, found throughout much of Europe as far north as Scandinavia and as ...
Mating begins by the call of a male tree frog, who is perched either on the underside or top of a leaf over a lake edge or a stream. Once a female has responded to the male's call, mating begins on the leaf in the amplexus physical position, in which the male wraps his arms around the female and attaches himself to her back.
