query: What do sawfishes eat?
passage: Sawfish
Sawfish are predators that feed on fish, crustaceans and molluscs.[2] Old stories of sawfish attacking large prey such as whales and dolphins by cutting out pieces of flesh are now considered to be myths and not factual.[1][59] Humans are also far too large to be considered potential prey.[71]
passage: Sawfish
Although fishing is the main cause of the drastic decline in sawfish, another serious problem is habitat destruction. Coastal and estuarine habitats, including mangrove and seagrass meadows, are often degraded by human developments and pollution, and these are important habitats for sawfish, especially their young.[4][100] In a study of juvenile sawfish in Western Australia's Fitzroy River about 60% had bite marks from bull sharks or crocodiles.[101] Changes to river flows, such as by dams, can increase the risk faced by sawfish young by bringing them into more contact with predators.[67][102]
