Many animal species have specific mating (or breeding) periods e.g. (seasonal breeding) so that offspring are born or hatch at an optimal time. In marine species with limited mobility and external fertilisation like corals , sea urchins and clams , the timing of the common spawning is the only externally visible form of sexual behaviour.
Sexual coercion among animals is the use of violence, threats, harassment, and other tactics to help them forcefully copulate. [1] Such behavior has been compared to sexual assault , including rape , among humans.
Furthermore, their mating systems have a wide range of variability, depending on the temporal availability and predictability of the females. These factors influence sperm competition levels in both intense male-male combative species and those species that participate in prolonged mate searching. [36]
Elephants can use their ears as threat displays in male-to-male competition. Sexual selection in mammals is a process the study of which started with Charles Darwin's observations concerning sexual selection, including sexual selection in humans, and in other mammals, [1] consisting of male–male competition and mate choice that mold the development of future phenotypes in a population for a ...
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. [ 1 ] [ 2 ] This is an aspect of mating . Many aquatic animals use external fertilization , whereas internal fertilization may have developed from a need to maintain gametes in a liquid ...
(Ischnura elegans) mating. In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms for the purposes of sexual reproduction. Fertilization is the fusion of two gametes. [1] Copulation is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization. [2]
Relationships can be wild. At the Louisville Zoo, that takes on a more literal meaning.. Scattered among the dens, nests, and coves are pairs of animals that have mated and even built bonds together.
Herons provide a great example of how cosmetic coloration is related to mate choice and sexual selection. In the whistling heron, they develop a yellowish color on their neck, stomach, and tail due to the powder feathers. The coloration due to the powder is more intense during breeding season.
