10 Trans-Gendered Creatures In The Animal Kingdom

Animals, Lists, Nature, Optical Illusions, Science, Shocking

With all of the recent sexuality debates going around the world, it should come as no surprise to everyone that even animals can be trans-gendered or multi-gendered. Charles Darwin, the renowned biologist who wrote entire books on evolution, proposed that due to competition amongst males for a female partner, some members of certain species have morphed their gender. In the eyes of an alpha male, this morphing allows the creature to appear as less of a threat. Here are ten animals that are trans-gendered or multi-gendered within the animal kingdom.

Marsh Harriers

Over 40 percent of Marsh Harriers will spend their entire lives with feathers that are seen on females. These males are about 30 percent smaller and lighter than normal males of the species.

Bluegill Sunfish

There are three different types of Bluegill Sunfish: parentals, satellites, and sneakers. Parentals will build nests and attract females. Satellites act and look like females, but are males and can release sperm. Finally, sneakers are the smallest, and are males pretending to be younger fish.

Red and Olive Colobus Monkeys

Red and Olive Colobus Monkeys are Old World monkeys that tend to live in a single-male dominated group. Males are often chased away from the pack when they are old enough. Some males, however, remain in a weird in-between stage where their genitals mimic that of a female, but they are still male.

Giant Australian Cuttlefish

The Giant Australian Cuttlefish is a bizarre creature. They have huge, doughnut-shaped brains, developed eyes to avoid predators, and their males outnumber the females 11:1, which is a bit of a mating issue. Some males imitate the coloring of a female to remain undetected while traveling through another male’s territory.

Western Side-Blotched Lizard

The Western Side-Blotched Lizard have an orange throat, which means they are dominant and the biggest in size. The blue-throated males defend the females from the yellow-throats, but run from orange throats. Next, the blue-throated males tend to form a close bond with a single female. Finally, the yellow-throated males have the same colors as females and can sneak past more dominant members of the species.

Spotted Hyenas

Spotted Hyenas can often be mistakes as female when they are actually a male. Both sexes have the same body type and size, and both have a set of testes and a penis. The female’s penis becomes erect when near familiar members, too.

Midshipman Fish

The Midshipman Fish is found along the coast from California to Alaska. They are remarkable creatures that have been found to produce a humming noise that gets incredibly loud. The males of the species are “multi-gendered,” meaning one kind makes noise to attract partners, while another is silent. The silent male fertilizes eggs and acts like a female.

The Bellbird

There is a type of Bellbird that has both the markings of a male and that of a female, as well. Sometimes the calls form said bird are male, and sometimes they are female.


Clownfish, the very distinct orange-and-white patterned fish, live within a certain pecking order. The senior breeding female is dominant, while her subordinate male comes second. The rest of those in the group don’t breed. The submissive male, however, can change sex from male to female when the breeding female dies.

Red-sided Garter Snakes

Red-sided Garter Snakes tend to hibernate as groups, with up to eight thousand in a single den. Male garters will sometimes emit female pheromones in an effort to attract other females for breeding.
