The Irrawaddy river shark (Glyphis siamensis) is a species of requiem shark, family Carcharhinidae, known only from a single museum specimen originally caught at the mouth of the Irrawaddy River in Myanmar. A plain gray, thick-bodied shark with a short rounded snout, tiny eyes, and broad first dorsal fin, the Irrawaddy river shark is difficult to distinguish from other members of its genus without anatomical examination. Virtually nothing is known of its natural history; it is thought to be a fish-eater with a viviparous mode of reproduction. The International Union for Conservation of Nature (IUCN) has assessed this species as Critically Endangered, as its distribution is extremely limited and suffers heavy fishing pressure and habitat degradation.

Famous quotes containing the words river and/or shark:
“We are bare. We are stripped to the bone
and we swim in tandem and go up and up
the river, the identical river called Mine
and we enter together. No one’s alone.”

“Oh, the shark has pretty teeth, dear—
And he shows them pearly white—
Just a jackknife has Macheath, dear—
And he keeps it out of sight.”
