Fishing cat
Summary
The fishing cat (Prionailurus viverrinus) is a medium-sized wild cat of South and Southeast Asia. Since 2016, it is listed as Vulnerable on the IUCN Red List. Fishing cat populations are threatened by destruction of wetlands and have declined severely over the last decade. The fishing cat lives foremost in the vicinity of wetlands, along rivers, streams, oxbow lakes, in swamps, and mangroves.
The fishing cat is the state animal of West Bengal.
Felis viverrinus was proposed by Edward Turner Bennett in 1833 who described a fishing cat skin from India. Prionailurus was proposed by Nikolai Severtzov in 1858 as generic name for spotted wild cats native to Asia. Felis viverrinus rhizophoreus was proposed by Henri Jacob Victor Sody in 1936 who described a specimen from the north coast of West Java that had a slightly shorter skull than fishing cat specimens from Thailand. There is evidence that the nominate taxon and the Javan fishing cat are distinguishable by skull morphometrics.
Phylogenetic analysis of the nuclear DNA in tissue samples from all Felidae species revealed that the evolutionary radiation of the Felidae began in Asia in the Miocene around . Analysis of mitochondrial DNA of all Felidae species indicates a radiation at around .
The Prionailurus species are estimated to have had a common ancestor between , and .
Both models agree in the rusty-spotted cat (P. rubiginosus) having been the first cat of the Prionailurus lineage that genetically diverged, followed by the flat-headed cat (P. planiceps) and then the fishing cat. It is estimated to have diverged together with the leopard cat (P. bengalensis) between and .
The following cladogram shows the phylogenetic relationships of the fishing cat as derived through analysis of nuclear DNA:
The fishing cat has a deep yellowish-grey fur with black lines and spots. Two stripes are on the cheeks, and two above the eyes running to the neck with broken lines on the forehead. It has two rows of spots around the throat. The spots on the shoulder are longitudinal, and those on the sides, limbs and tail are roundish.
