9 Strangest Animal Courtship Displays Around the World

From dancing prairie chickens to male pufferfish sculpting the seafloor, these nine examples show how animals signal and compete for mates.

Animals attract mates in remarkably different ways: some dance or sing, some build elaborate displays, and others compete with rivals. These nine examples are often called “mating rituals,” but the phrase usually describes courtship—the signals and behaviors that can precede mating or spawning, not the act itself. In birds, displays can communicate willingness to mate and help a potential partner assess a suitor.

What are the strangest animal mating rituals?

“Strangest” is a matter of perspective, not a scientific ranking. The examples below show how varied courtship can be, from a bird offering a stone to a fish shaping the seafloor. Each behavior belongs to a particular species or group; it should not be assumed to happen identically across all related animals.

1. Greater prairie chickens boom and dance

On the Northern Great Plains of the United States, male greater prairie chickens gather at display sites called leks or booming grounds. They dance, call, raise their neck feathers, and inflate yellow-orange air sacs. Males compete for display positions, and the dominant bird performs most of the mating, according to World Wildlife Fund.

2. Seahorses twine tails

During courtship, seahorse partners may brighten in color, twist their tails together, and swim in circles. The details and timing can differ among species, so this choreography is not universal. Seahorses are also unusual because males carry the developing offspring. World Wildlife Fund describes these courtship behaviors and the male’s role in carrying young.

3. Gentoo penguins present stones

A male Gentoo penguin may present a stone to a female as a courtship gesture. Once paired, the birds gather stones and plants for a nest and share incubation. The behavior is reported for Gentoo penguins around the Antarctic Peninsula, nearby islands, and sub-Antarctic islands; it is not a universal proposal custom among penguins. World Wildlife Fund describes the stone presentation and shared nesting work.

4. Peacock spiders combine color, movement, and vibration

Male peacock spiders in Australia raise colorful abdominal flaps and wave their legs. In the species Maratus volans, peer-reviewed research documents both visual and vibratory components of courtship (PLOS ONE). World Wildlife Fund writer Callie Cho reported in 2026 that a display can last “up to 50 minutes, or until the female decides to mate” (World Wildlife Fund). That is a possible maximum, not a typical duration. A female may eat an unimpressive suitor, but this is a possible outcome, not an inevitable one.

5. Blue-footed boobies lift their feet

To attract a female, a male blue-footed booby spreads its wings, points its beak upward, alternately lifts its bright feet, and whistles. This courtship display occurs along Pacific coasts of Central and South America and in the Galápagos; it is a signal to a potential mate, not the mating act itself. World Wildlife Fund describes the display.

6. Bowerbirds build a stage, not a nest

Male bowerbirds in Australia and New Guinea build display structures called bowers and decorate them with colored or shiny objects. A male may dance while holding a trinket as a female inspects both the structure and the suitor. The bower is not the nest: after mating, the female builds a separate nest, as explained by the San Diego Zoo Wildlife Alliance. For more on bowerbird displays, see the American Museum of Natural History.

7. Male pufferfish sculpt the seafloor

In Japan, males of the pufferfish genus Torquigener create underwater circular patterns of peaks and valleys that attract females. World Wildlife Fund reports that a circle can reach up to 2 meters in diameter—a reported maximum, not a typical size (World Wildlife Fund). Sources describe the structure’s role in courtship and spawning; calling it a nest without qualification can give the wrong impression. Scientific Reports examines the structures and their association with spawning.

8. Some deep-sea anglerfish males attach to females

In certain deep-sea anglerfish species, a male finds a female and bites onto her; in some species, the attachment becomes permanent. This striking reproductive strategy is not shared by every anglerfish. The Nature Conservancy describes the behavior and its limits across the group (The Nature Conservancy).

9. Red deer stags compete for access to females

Male red deer in Europe and Asia establish and defend areas, roar, walk alongside rivals, and sometimes clash antlers. These contests are competition among males for access to females, rather than a courtship ritual performed by a mating pair. World Wildlife Fund describes the behavior.

Why do animals dance, build, or compete to attract mates?

Courtship is a form of communication and mate assessment. A display can signal willingness to mate and give a potential partner clues about a suitor. In birds, displays may also offer indications of health, vigor, or the ability to provision young, according to the Cornell Lab of Ornithology. The exact information conveyed depends on the species and behavior; there is no single explanation that covers every example.

Across these animals, the method varies: prairie chickens, boobies, and spiders emphasize movement and sound; bowerbirds and pufferfish construct displays; Gentoo penguins use a material gesture; and red deer stags compete. These are different strategies, not points on a measurable scale of oddness.
