Introduction
Reproductive behaviour and physiology shows much placicity in amphibians. Gender and breeding season are controlled by genetics, photoperiod, temperature, humidity and food or mate availability.
Reproductive Traits
Amphibian reproduction can by classified by primitive traits that are shared by most fish.
Oviparous
- Lay eggs with little or no embryonic development within the mother.
- Eggs laid singly,in clusters or in strands depending on the species of amphibian.
Anamniotic Eggs
- No shell.
- Require moisture as there is only a single membrane around the embryo.
- Amnion is absent.
Cloaca
- Shared urinary, reproductive and excretory channel.
