Sometimes, male guppies also try to forcefully mate with Skiffia bilineata (goodeid) females, which resemble guppy females and tend to share the same habitat, even when guppy females are available.

Dolphins feed largely on fish and squid, but a few, such as the orca, feed on large mammals such as seals. Male dolphins typically mate with multiple females every year, but females only mate every two to three years. Calves are typically born in the spring and summer months and females bear all the responsibility for raising them.
One proposal for the adaptive function of homosexual behavior is the formation of alliances and mutual social benefit to the animals.

These ...
The male that wins a fight may also have the chance to mate with a larger number of females and will therefore pass on his genes to their offspring. [ 3 ] Historically, it was believed that only humans and a small number of other species performed sexual acts other than for reproduction, and that animals' sexuality was instinctive and a simple ...

[22] [23] River dolphins are polygynous, meaning male river dolphins typically mate with multiple females every year, but females only mate every two to three years. Calves are typically born in the spring and summer ...
Meanwhile, in 2018 a study on male bottlenose dolphins found that they retain their “names” into adulthood just like females — it was previously thought males abandoned their signature ...
Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals.
