What Did The Swamp King Do To These Rare Sawfish?

A freshwater crocodile has been caught on camera making a quick meal of an endangered sawfish.

Freshwater sawfish are internationally listed as critically endangered and they are the only of the five sawfish species with a juvenile freshwater stage. Young sawfish spend about 4-5 years in the river before migrating to the ocean to mature and breed.

Their upstream migrations are fraught with danger, and it is doubtful that they always survive. These scars indicate that the freshwater crocodile attempted to capture and consume sawfish regularly, but was unsuccessful possibly due to the prey’s size, sensing ability and defences.

Freshwater sawfish are internationally listed as critically endangered and they are the only of the five sawfish species with a juvenile freshwater stage. The researchers proposed removing or altering the barriers in the artificial stream because they attract crocodiles and bull sharks, which would allow sawfish to travel safely.

Professor Morgan said the scarred crocodiles looked healthy, but attacks by larger crocodiles can be fatal, especially for newborn sawfish migrating upstream. Three natural predators, including two protected crocodile species, have the potential to severely decimate freshwater sawfish populations.
