Irrawaddy River

Irrawaddy river shark

The Irrawaddy river shark, Glyphis siamensis, is a shark of the family Carcharhinidae, found in the tropical waters of the eastern Indian Ocean off the coast of Burma.

The only known specimen is from the Ayeyarwady River, near Yangon (Rangoon). Until very recently, this species was regarded as an aberrant specimen and possible synonym of (the same species as) the bull shark, but shark systematist Leonard Compagno now considers it to be a member of the genus Glyphis, distinct from the other known species.

It is viviparous but its biology is poorly known.
