Cheers Stewy

Indeed! Full marks for Stewy!!! :biggrin2: Seems like I may have to make this harder if we ever go another round...

The Stout Infantfish is the smallest fish ever discovered...

"The recently described Stout Infantfish is arguably the world's smallest (and lightest) vertebrate species. The largest specimen captured to date is a gravid female that is 8.4 mm in standard length and weighs about 1 mg (one millionth of a kilogram).

Very little is known of Stout Infantfish biology. Females reach sexual maturity by 7 mm to 8 mm in length and males mature by 6.5 mm to 7 mm. All six specimens have been found in depths of 15 m to 30 m in coral-reef lagoons in the vicinity of Lizard Island, Great Barrier Reef, Australia.

It is likely that the Stout Infantfish is more widely distributed. The first specimen was collected in 1979 by Jeff Leis during fieldwork based at the Australian Museum's Lizard Island Research Station. Since then, another five specimens have been collected by Jeff Leis. All six were used in the description of the new species.

Only two other species of infantfishes are currently known, S. praematura and S. pietschmanni. The Stout Infantfish differs from the other species of infantfishes by having a deeper body, fewer dorsal and anal fin rays and larger eyes. The urogenital papilla of males differs in shape from those of other Schindleria species.

The species name, brevipinguis, comes from the Latin brevis, meaning short (refers to the small size of the species) and pinguis meaning stout (refers to the deeper, broader body of this species compared with other species in the genus).

The Family Schindleriidae, which is related to gobies (Johnson & Brothers, 1993), contains tiny fishes that live in and near coral reefs. They may be the most abundant coral-reef fishes in the world, reaching abundances of seven per cubic metre in waters near reefs (Leis, 1978). A recent paper by Kon and Yoshino (2002), based on otolith rings, showed that infantfishes are very short-lived. In the Ruykyus Islands, Japan, they reach maturity in 23 to 60 days."
