Climbing perch
The climbing perch (Anabas testudineus) is a species of amphibious freshwater fish in the family Anabantidae (the climbing gouramis). A labyrinth fish native to Far Eastern Asia, the fish inhabits freshwater systems from Pakistan, India, Bangladesh and Sri Lanka in the west, to Southern China in the east, and to Southeast Asia west of the Wallace Line in the south. It is likely that Anabas testudineus is a species complex, with the binomial name applied to what are actually several different species. With further study, populations of this fish may be divided up into separate species and given new names. In Nepalese Terai it is called "Pothiya"
The climbing perch is euryhaline and can grow to 25 cm (9.8 in) in total length. Outside its native ranges, it is an invasive species that can live without water for 6–10 hours and move on land by crawling/wriggling the body with its pectoral fins. It is believed that the fish may be invading new territories by slipping aboard fishing boats. The fish has been established in some islands east of the Wallace Line, in eastern Indonesia and Papua New Guinea, and is also believed to be advancing toward Northern Australia. In late 2005, the fish was discovered on Saibai Island and another small Australian island in the Torres Strait north of Queensland, about three to four miles south of Papua New Guinea.
