Pterothrissus gissu

Pterothrissus gissu, also known as the Japanese gissu, is a species of ray-finned fish in the family Albulidae. The Japanese gissu is an extremely rare marine fish that is distributed in deep water off northwest Pacific Ocean. Due to its natural habitat being in deep offshore waters, there is a lack of sufficient data on the Japanese gissu. This fish is known to pass through a leptocephalus larval stage, but only metamorphosed specimens have been available This species is the only member of its genus.

2 occurrences of Pterothrissus gissu on record, most of them in the Pleistocene. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

2 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.
