[2] It held the record for the shortest known vertebrate until the frog Paedophryne amauensis was formally described in January 2012, while the parasitic males of the anglerfish Photocorynus spiniceps are but 6.2 millimetres (0.24 in) long. Phylogenetic diversity index (Ref. 69278 ): 3.0 ±0.4 se; Based on size and trophs of closest relatives. Bayesian length-weight: a=0.00759 (0.00286 - 0.02011), b=3.04 (2.81 - 3.27), in cm Total Length, based on LWR estimates for … It only measures 7.9mm long (0.31 inch). The world's smallest fish is a species found in Southeast Asia, known as Paedocypris progenetica, which averages 7.9 mm for females. Male individuals of the species anglerfish Photocorynus spiniceps have been documented to be 6.2-7.3 mm at maturity, and thus claimed to be a smaller species. It's important to mention that the dwarf pygmy goby (Pandaka pygmaea) is also one of the smallest fish in the world by mass and is also one of the shortest freshwater fish as well. The Paedocypris progenetica’s name derives from the Greek words ‘Paideios’, which means children, ‘Cypris’ meaning Venus, and the Latin ‘Progenesis’ which means precocious reproduction.
