“…Generally, the caudal complex of Schindleria is a unique propulsion system. It comprises modified preural vertebrae 2 and 3, an extremely elongate urostyle, a relatively large, triangular hypural plate, a system of modified muscles with an elongated pair on each side of the urostyle, and a caudal fin with segmented and partly branched principal caudal fin rays (Ahnelt and Sauberer 2018;Robitzch et al 2022).…”

“…Although some recent studies investigated sexual dimorphism (Robitzch et al 2021a), lunar migration cycles (Robitzch et al 2021b), and swimming mode (Robitzch et al 2022) of Schindleria, the entire lifecycle, habitat, and basic biology and ecology of these enigmatic fishes are virtually unknown and still need detailed exploration. Nonetheless, the collection in which this new species was found may allow for the inference of a few more details on the habitat or distribution of S. qizma.…”

“…They are also among the fastest reproducing vertebrates in the world with an extremely short generation time (of up to nine generations per year) reaching maturity at 23 to 60 days of age (Kon and Yoshino 2002). So far, very little research has been undertaken on the biology and ecology of this taxon (Robitzch et al 2021(Robitzch et al , 2022, likely because species of Schindleria are tiny, translucent, and resemble larval stages for which they are easily mistaken (Bogorodsky and Randall 2019;Robitzch et al 2021).…”

Species of the gobiid genus Schindleria are among the smallest and fastest reproducing vertebrates of the oceans. We describe a new species, Schindleria qizma, from the Red Sea, Saudi Arabia. It is an extreme example of progenesis, within the already paedomorphic genus, with morphological traits clearly differentiating it from its congeners. Schindleria qizma has a unique, unflexed notochord with a straight urostyle of which the tip is inserted into the hypural cartilage, rather than the typical flexed notochord with an upturned urostyle of the other species of Schindleria. Schindleria qizma belongs to the short dorsal-fin type of Schindleria. It is further characterized by an elongated but relatively deep body; a short dorsal fin originating just slightly anterior to the anal fin (predorsal-fin length 59.4% of SL vs. preanal-fin length 60.2% of SL); a head continuously increasing in depth posteriorly with a straight dorsal profile; a short snout (18.6% of head length); large eyes (34.4% of head length); a short pectoral-radial plate (6.3% of SL); 13 dorsal-fin rays; 11 anal-fin rays; 0–2 procurrent rays (where the last procurrent ray is short, if present); an anal fin with the first anal-fin ray situated opposite the second dorsal-fin ray; toothless oral jaws; females with few (10–11, total) but very large (4.6% of SL) eggs and with a conspicuous urogenital papilla characterized by a wide urogenital opening flanked by two long, bilobed projections; a dorsally pigmented swim-bladder; blackish, iridescent eyes, capped by a silvery layer with irregular rows of black dots or blotches; and no additional external pigmentation on its body, at least in preserved specimens.
