Hairy Animals

Also known as:

  • Hypertrichosis
  • Hirsutism

Things that are rare, or different from what is considered "normal", always attracts interest. For example, hair or feathers that are longer than is usual in their species, or grows in unusual places, or unusual ways. The following are some examples of animals, and people, who are bit hairier than the norm--sometimes for reasons we know and understand, and sometimes quite mysteriously.

Wild Animals

Gazelle

Paolo Torchio photographed an antelope with an unusually hairy coat. It appears to be a young female Thomson's gazelle and it was located in the Masai Mara National Reserve (Kenya). And in 2010 Robert Berntsen later photographed the same animal again.

The cause of its condition is not known but it can be generically described as having hypertrichosis (excessive hair).It has been suggested that this might be symptomatic of Cushings disease.

Domestic Animals

Many domestic species have naturally occurring long-haired forms, which may be selectively perpetuated as 'long-hair' or 'angora' breeds. Sometimes these breeds have been around long enough that it is easy to forget that their species is not naturally long haired (e.g. cats, gerbils, mice, teddy bear hamster).

Birds

"Featherduster" Birds

Various bird species such as budgies and parakeets (shown right) sometimes produce birds whose feathers are long, curly and constantly growing. This condition (colloquially called "Feather Duster" for obvious reasons) is caused by a recessive gene whose action causes the mechanisms controlling feather growth are inactivated. Some argue that feather duster birds should be euthanized as their feathers can impede their movements and they often have a shortened lifespan, equally it can be argued that those with the resources to care for accidental occurrences of this mutation should feel free to do so. However it is not a trait that should be bred for deliberately.

The Phoenix Rooster

Some breeds of chicken have been bred for amazing long tail feathers: for example the Japanese Yokohama and Onagadori and the related European Phoenix rooster.

Dogs

Across all dog breed there are only three genes that control hair length.

Gibbon

Hypertrichosis, involving growth of hair on the face, has been described in a gibbon.

Guinea Pigs

Guinea pigs comes in several long-hair varieties. The short-haired version is often referred to as "American" and the long-haired varieties as as Peruvian and Sheltie (a.k.a. Silkie).

Horses

Cushings Disease

In older horses over-growth of the coat may be caused by hyperadrenocorticism, also called Cushings disease, or by other conditions that ause disruption of normal pituitary function. For other examples of Cushing's curly coat see: Palimino.(In other animals such as dogs, Cushing's disease leads to hair loss and baldness).

Hypertrichosis has also be observed in horses with certain forms of cancer such as lymphoma where the function fo the pituitary gland is affected.

"Wonder Horses"

Genetically and physically normal horses may grow a particularly long mane and/or to that falls to the ground, or even longer. Some horses with very long manes and tales have been exhibited in circuses such as several Oregon horses exhibited under the name of Linus. The first Linus dates from 1884 and was purchased by the Eaton brothers as an sideshow animal. His long hair may result from a lineage including Clydesdales and wild horses from the Oregon region that were already known for their long manes and tails. Linus's son (Linus 2) continued as an exhibit after his sire was killed by lightning. At least one other horse has also be exhibited as "Linus", whose lineage is not known.

Another sideshow horse with long mane and tail was exhibited in the 1890s and went by the name of White Wings,

The current record holder for longest tail is an American paint horse called Summer--with an attractive black and white tail measuring in at 12 feet, six inches.

Human Hypertrichosis

Bearded ladies are usually women who have higher than typical levels of androgens, causing them to exhibit secondary sexual characteristics more commonly found on on men. However the hypertricosis in women may also be caused by many other conditions such as polycistic ovary syndrome.


In men hypertrichosis may cause hair growth across most of the body including the entire face. Examples include:

Hypertrichosis can be produced by a range of pharmaceuticals including Minoxidil and Phenytoin.

Human Hair Growers

As human head hair is constantly growing it is possible to grow it to a very impressive length. One promonant example is the singer Crystal Gayle who has trademark long dark hair which she wears at a length that touches the floor.

The current record holder for longest hair is Xie Qiuping (right), at 5.6m (18'6").

The longest beard at 1.9m belongs to Sarwan Singh, Radhakant Bajpai is known for extraordinary ear hair, and the longest eyebrows (15cm) belong to Japanese woman Edogawa-ku.

Distinguished mention also goes to Tran Van Hay (deceased), Georgia Sebrantke, and the Sutherland sisters.

Animal Hair Growers

Many other animals have hair that continues to grown unless cut. Thus you will see floor length hair and creatures such as alpaca.

Sheep

A sheep that goes unshorn for several years can develop an impressively round fleece, such as with Shrek (shown right). Shrek is a Merino who managed to evade shearing for six years prior to becoming a minor media celebrity in 2004. When "he" was finally sheered, the fleece weighed an astounding 27 kg (60 lb) and he turned out to be a she.

Fish

Of course fish do not have hair, but the do grow fins and some fish (such as danios) come in varieties with unusually long fins.
