Reptiles come in all shapes and sizes, from tiny geckos to mammoth dinosaurs. Their reproductive methods and behaviors generally differ greatly from mammals, though there are some similarities. Among reptiles, differences in courtship rituals and reproduction can be quite different as well. Although most reptiles lay ...
Most reptiles are oviparous, although several species of squamates are viviparous, as were some extinct aquatic clades – the fetus develops within the mother, contained in a placenta rather than an eggshell. As amniotes, reptile eggs are surrounded by membranes for protection and transport, which adapt them to reproduction on dry land.
Reptiles: Reproduction "From Egg to Adult" Synopsis: Some reptiles lay eggs and others deliver live young.Females do not need the presence of a male in order to lay eggs. There are subtle differences between males and females in most species of reptile, but in others, the differences are obvious.
How familiar are you with the “birds and the bees” of reptile reproduction? As reptiles increase in popularity, interest in breeding is growing. Other reptile owners are doing such a good job of caring for their pets that the herps are growing and reaching sexually maturity. For example, we’re seeing an unprecedented number of adult […]
Reptile reproduction varies between species. Most reptiles reproduce sexually, while a few are capable of asexual reproduction. There are six families of lizard and one family of snake that are known to reproduce asexually through parthenogenesis. Depending on the species, reptiles reproduce by either laying eggs or giving birth to live young.
Oviparous reptiles lay amniotic eggs. Amniotic eggs have a hard shell which protects the embryo, and a special membrane to prevent the embryo from drying out. Turtles, crocodiles, and tuatara are all oviparous as are some species of lizard and snake. Crocodile egg
Fertilization for both oviparous and viviparous reptiles occurs inside the female. First they conduct a courting ritual which sometimes includes male color displays and mating dances. The male then inserts his penis or hemipene into the female cloaca, says Wissman. Reptiles use the cloaca for excreting digested food and reproduction.
Amphibian reproduction has more in common with that of fish than it does of mammals or even reptiles. While all of these animals reproduce sexually (meaning that the species consists of males and females and mating involves the fetilization of eggs by sperm), reptiles and mammals reproduce through internal fertilization (inside the female) whereas amphibians practice external fertilization.
Reptiles are a group of animals characterized by a certain set of features. For one thing, they have scales or scutes instead of the fur and hair that mammals have. Their method of reproduction ...
Reproduction (Baby animals!) Another difference is the way animals give birth to their young (babies). Most baby mammals grow inside their mother until they are born. This is something that makes mammals different, because most other kinds of animals do something else...
