Are there any freshwater sharks in PNG"?
Yes, Speartooth sharks (Glyphis glyphis) and New Guinea River sharks (Glyphis garricki), are two rare freshwater shark species sometimes seen in PNG.
These so-called “river sharks” of the genus Glyphis are some of the most rarely seen, poorly understood, and critically endangered sharks on Earth.
Recognizable by their relatively small eyes, Glyphis sharks are found in large rivers and in nearby coastal ocean habitats in parts of the Indo-Pacific including Northern Australia, Papua New Guinea, Indonesia, India and Pakistan.
