Some animal species are engage in some strange sexual behaviors like prostitution, sexual

cannibalism, necrophilia, sex between adults and juveniles and autofellatio and oral sex.

Adelie Penguin (Pygoscelis adeliae)

Unbelievable it seems but prostitution is not limited to human beings. A committed female Adelie Penguin will

exchange sexual favors with strange males for the pebbles she needs to build it nests. Because of this, the

penguin community experiences a high STI rate, as well as a high occurrence of domestic abuse. An Adelie

Penguin is a type of penguin common along the entire Antarctic coast and Africa in its nearby islands. They

are among most southerly distributed of all seabirds.

Stoat (Mustela erminea)

A male Stoat will mate with infant females of their species. Mating is often forced by the male, who does not help

raise the offspring. This apparently is a natural part of their reproductive biology - there is a delayed gestation

period, so these females give birth the following year when they are fully grown. The Stoat is known as the Ermine

or Short-tailed Weasel in North America.

Spotted Hyena (Crocuta crocuta)

Similarly, a male Spotted Hyena which attempted to mate with a female but failed to do so will eventually turn to its

ten-month-old cub, repeatedly mounting it and ejaculating on it. The cub sometimes ignored this and sometimes

struggled “slightly as if in play”. The mother will not intervene. The Spotted Hyena or Laughing Hyena of

sub-Saharan Africa is the largest of hyenas.

Bonobo (Pan paniscus)

Infants and children in Bonobo societies often are involved in sexual behavior. Sexual activity happens within the

immediate family as well as outside it. The Bonobo is also commonly called Pygmy Chimpanzee, Dwarf or Gracile

Chimpanzee. It is a great ape and one of the two species making up the genus Pan.

Mole (Talpidae)

It has been recorded that certain species of mole will impregnate newborns of their own species. It is not clear if this is forceful or not.

Sexual Cannibalism

Sexual cannibalism, which has been documented in arachnids, insects and amphipods, is a phenomenon in which

a female organism kills and consumes the male before, during, or after copulation. Although it does confer some

known advantages to reproduction, whether or not the male is complicit has not been scientifically determined.

Black Widow Spider (Latrodectus mactans)

The Black Widow Spider is one of the few animals that practice sexual cannibalism. It is well known for the

distinctive black and red coloring of the female of the species and for the fact that she will occasionally eat

her mate after reproduction. The highly venomous species is native to the US. The female Black Widow’s

venom is particularly harmful to humans (males almost never bite humans). Males that escape being consumed

by the females can go on to fertilize other females. This is a general misconception, as the name seems to

suggest that the males are invariably consumed after mating.

Goats, Primates, Hyenas and Sheep

Animals of several species are documented as engaging in both autofellatio and oral sex. Although easily

confused by lay-people, this is a separate and sexually oriented behavior, distinct from non-sexual grooming

or the investigation of scents. Auto-fellatio or oral sex in animals is documented in goats, primates, hyenas

and sheep.

What’s necrophilia? Well, necrophilia or necrolagnia is the sexual attraction to corpses or dead bodies. A few

animals are known to be engaging in necrophilia.

Mallard Duck (Anas platyrhynchos)

The colorful and handsome Mallard is one of the most popular ducks in the world. Male Mallards occasionally

chase other males in the same way they chase female. In one documented case, a male Mallard copulated with

another male he was chasing after it had been killed when it flew into a glass window. The living drake picked at

the corpse of the dead one for a few minutes and then mounted the corpse and began copulating with it. The act

of necrophilia lasted for about 75 minutes, in which time; the living drake took two short breaks before resuming

with copulating behavior.

Praying Mantis (Mantidae)

In the case of a Praying Mantis, necrophilia could be said to be part of their methods of reproduction. The larger

female will often decapitate or even eat her mate during copulation. However, given that the sexual activity of a

male mantis is controlled by a brain-like ganglion in his abdomen it may not be appropriate to refer to him as a

“corpse”, even when he is decapitated.
