Definition

Noun: A leather carp is a variety of the domestic common carp (Cyprinus carpio) that is characterized by having very few scales or being completely scaleless. Unlike the typical scaled carp, its skin is smooth and leather-like, which gives the variety its name.

Usage

The term is used specifically in ichthyology, aquaculture, and angling to describe this distinct morphological variant of the common carp. * The angler was thrilled to catch a large leather carp, noting its unique, smooth skin. * In the breeding pond, the leather carp can be easily distinguished from the mirror carp by its complete lack of scales.

Advanced Usage

• The trait is a genetic mutation. A leather carp is the result of breeding two mirror carp (which have irregular, large scales) together, which can produce fully scaleless offspring.
• The term is used in contrast to other scale-pattern varieties: the fully-scaled "common carp," the irregularly-scaled "mirror carp," and the linear-scaled "linear carp."

Variants and Related Words

• Mirror carp (n): A related variety of domestic carp with a few large, mirror-like scales scattered irregularly across its body. The leather carp is genetically linked to this variety.
• Common carp (n): The standard, fully-scaled species from which all ornamental and domestic varieties, including the leather carp, are derived.

Synonyms

• Scaleless carp: A descriptive synonym emphasizing the defining physical characteristic.

Related Terms

• Koi (n): Ornamental colored varieties of the common carp, which can also exhibit scale patterns including the leather (doitsu) type. A leather carp is not inherently a koi, but koi can be bred to have the leather carp's scaleless trait.
