As a result, they may be loud when they need to be quiet, or they may stumble into danger.” 5. She could read the kittens’ signals, but they might not be able to see or understand their mother’s. “But consider a melanistic mother cat with spotted kittens. “One example is that mother cats can lift their heads and stretch their ears to flash the white marks to signal possible danger to their cubs, or to keep quiet if prey is nearby,” zoologist Maurício Graipel of the Federal University of Santa Catarina in Brazil told Smithsonian Magazine.
These markings indicate a variety of messages, ranging from friendly signals to “back off!” A black leopard lacks the white markings on its ears and tail that other leopards use to signal to each other. A 2019 study in PLOS ONE suggested that markings critical to feline communication are hidden in melanistic leopards. But, there is also a major disadvantage of melanism for these big cats. The leopard’s dark coloration may help it better camouflage at night, warm faster in the sun, and even ward off parasites. Melanism is found in about 11 percent of leopards globally, but most of these leopards live in the forested habitats of Southeast Asia. Scientists stated that the last confirmed sighting of a black leopard on the African continent was in 1909 in Ethiopia. The only difference between a black leopard and other leopards is the color of its coat. This mutation affects the regulation of melanin, resulting in an overproduction of dark pigments and the black coloration. Its distinct coat coloration is caused by a genetic mutation called melanism, which has the opposite effect of albinism. The black leopard photographed using a Camtraptions Camera in Kenya.

Piebald deer, however, are protected in fewer states, and this protection is often based on how much of the deer’s coat is white. It is illegal to kill albino deer, which lack all pigment and are completely white, in several states, including Illinois, Iowa, and parts of Montana, Tennessee, and Wisconsin. Piebaldism also makes deer susceptible to predation as they are easier to see with white coloring. It can also cause an array of possible deformities, including changes to skeletal alignment like short legs and curved spines. Piebaldism does not just affect coat coloration. That makes this characteristic very rare, affecting less than two percent of the white-tailed deer population, according to David Osborn, wildlife research coordinator at the University of Georgia Deer Research Facility. Piebaldism is a recessive trait, which means both parents must carry the recessive gene for this coat coloration in order for them to produce a piebald offspring. Piebaldism is a genetic phenomenon that causes a lack of pigmentation in patches around the body.

The piebald deer in Cary, North Carolina. Because gynandromorphic birds are so rare, most of what is known about their behavior and the effects of this mutation comes from just one bird-a half-male, half-female northern cardinal found in 2008.
This mutation is likely present across all bird species, but it is harder to detect in a species where adult males and females look similar, Daniel Hooper, a postdoctoral fellow at the Cornell Lab of Ornithology, told National Geographic. Gynandromorphism is a very rare condition that is known to occur in insects, snakes, crustaceans, and birds. So, its brain is likely half-male, half-female, too. The cardinal not only appears half-male, half-female, but it also has the genetic makeup for both sexes. Gynandromorphism likely occurs because of an error during egg formation. This genetic anomaly is referred to as bilateral gynandromorphism because it causes a split right down the middle with half of the species’ body resembling a male and the other half a female.
