"The deepwater cisco (below) was a herring-sized fish with large silvery scales and a short back or dorsal fin. It weighed about 1 kg (2.2 lb). The longjaw cisco (above) was a close relative with a streamlined body and snout."

"The New Zealand grayling had silvery to russet scales, and could grow to 50 cm (20 in) in length and weigh 1.4 kg (3 lb). The fish preferred to live in swiftly flowing rivers and streams."

"The Australian grayling is a relative of the New Zealand species, and it is in danger of suffering the same fate as its cousin. It lives in rivers along the coast of southeast Australia and Tasmania. It has been killed by river pollution, by the building of dams and weirs, and by overfishing."

Conspiracy theorists be like "I think the megalodon is still alive in deep sea trenches"

My brother in fish, it's too high pressure down there for anything large and alive to be down there

Polymerichthys, one of the weirdest extinct fish that I know, note the central, forward curving row of teeth on the palate for example.
