 Because of the potential threat they (or rather their "saw") represent to humans, they are sometimes killed before being brought onto the boat when accidentally caught.Because of the "saw", all sawfish are particularly prone to becoming entangled in fishing nets.Historically the longcomb sawfish has been recorded in 37 countries, but it has been extirpated from 2 and possibly extirpated from another 24, leaving only 11 countries where it certainly still survives.
