Paedocypris progenetica

The world's smallest fish on record, is a member of the carp family. The fish has a see-through body and a head that is unprotected by a skeleton. Photo courtesy of Maurice Kottelat, Carnol, Switzerland and Raffles Museum.



Scientists have found the smallest known fish in the peat swamps of Sumatra, an island in Indonesia.
Individuals of the Paedocypris genus—members of the carp family—can be just 7.9mm long at maturity. Paedocypris feed on plankton in pools of extremely acidic water in tropical forest swamps. Paedocypris progenetica has been claimed to be the smallest known species of fish and vertebrate in the world. The smallest mature female measured 7.9 mm and the largest known individual 10.3 mm.

Lead researcher, Dr Maurice Kottelat of the National University of Singapore, says the species has "a very rudimentary skull", which leaves the brain exposed.
These tiny fish are at great risk of extinction die to the rapid destruction of Indonesian peat swamps for oil palm plantations. According to Dr Susan Page at the University of Leicester, at the current rate of burning, peatlands in Borneo, Sumatra and Papua New Guinea could be destroyed before 2040, releasing a vast amount of carbon into the atmosphere.


Appearance
Their miniature transparent body lacks typical features characteristic of adult fish, for instance a bony skull structure around its brain, and it retains the post-anal larval-fin-fold along the ventral edge of the caudal peduncle, characteristic of fish larvae. They have a unique sexual dimorphism: The males have highly modified pelvic fins, with the first ray terminating with a hook-like projection of keratinized skin, supported by hypertrophied pelvic musculature. Males also have a pad of keratinized skin in front of the pelvic fins. It is hypothesized that these modified fins are used to grasp the female during mating, or to keep position over a spawning surface.

Habitat and conservation
Paedocypris progenetica lives in the dark colored peat swamps of the Indonesian island of Sumatra [lives in the peat swamps of Sarawak (Borneo). Their small size helps them to survive through extreme droughts, as they can live in small remaining puddles of acid water (pH as low as 2.9, at least 100 times more acidic than rainwater). Their habitat is threatened by forest fires, logging and plantations.
