The Predator, also known as Yautja (pronounced / j ɑː ˈ uː tʃ ə /, yah-OO-chə), [2] is the titular extraterrestrial species featured in the Predator and Alien vs. Predator science fiction franchises, characterized by its trophy hunting of other "challenging" species for sport.
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.
Steller's jays breed in monogamous pairs. [14] The clutch is usually incubated entirely by the female for about 16 days. [15] The male feeds the female during this time. Though they are known to be loud both day and night, during nesting they are quiet in order to not attract attention. [16]
Observed non-procreative sexual activities include non-copulatory mounting (without insertion, or by a female, or by a younger male who does not yet produce semen), oral sex, genital stimulation, anal stimulation, interspecies mating, same-sex sexual interaction, [2] [3] and acts of affection, although it is doubted that they have done this ...
A female capybara has arrived at a Florida zoo as part of a breeding program to bolster the population of the large South American rodents. Iyari, a 10-month-old capybara, went to the Palm Beach ...
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 ...
In evolutionary psychology and behavioral ecology, human mating strategies are a set of behaviors used by individuals to select, attract, and retain mates.Mating strategies overlap with reproductive strategies, which encompass a broader set of behaviors involving the timing of reproduction and the trade-off between quantity and quality of offspring.
Polygyny (/ p ə ˈ l ɪ dʒ ɪ n i /; from Neo-Greek πολυγυνία, from πολύ-(polú-) 'many' and γυνή (gunḗ) 'woman, wife') [1] is a mating system in which one male lives and mates with multiple females but each female only mates with a single male.
