International Sawfish Day

Held each 17 October since 2017 for the sawfishes, rays with a toothed snout and among the most threatened fish in the sea.

Sawfishes are rays with a long, flat snout edged with teeth, which they use to slash at schools of fish and to probe the mud. That snout tangles easily in nets, and with the loss of mangroves and estuaries all five species are now endangered or critically endangered. They have vanished from many coasts where they were once common, including much of the Indian and Pakistani coast. International Sawfish Day was started in 2017 by zoo and aquarium associations in Europe and America and the Sawfish Conservation Society, and is marked with talks at aquariums.

Still to be written: Largetooth sawfish, Smalltooth sawfish, Longcomb sawfish, Knifetooth sawfish.
