Fish of the Week‪!‬ U.S. Fish and Wildlife Service

Meet the Smalltooth Sawfish! Learn all about its saw-like rostrum, the threats it faces, how NOT to take a photo with a sawfish, and what's being done to understand and conserve these incredibly cool critters. Our guest is John Carlson with NOAA Fisheries Service's Southeast Fisheries Science Center.

Get to know a huge, bendy, slow-moving shark that looks like a giant log, has cantaloupe-sized eyeballs, and loves a delicious whale fall. Our guests are Cindy Tribuzio and Beth Matta with NOAA. Beth is a research fisheries biologist in the Age and Growth Program at the Alaska Fisheries Science Center and Cindy is a research biologist with the Alaska Fisheries Science Center's Auke Bay Laboratories.

You: running your hands through warm sand at the beach. Also you: finding out it might have passed through the anus of a fish. Meet the Bumphead Parrotfish: beach-making "bulldozer of the sea" and gargantuan coral-chomping champion. Our guests are Richard Hamilton with The Nature Conservancy and Alan Friedlander from the Hawaii Institute of Marine Biology and National Geographic's Pristine Seas.

Get to know the Milkfish, a big, shiny, powerful fish known locally in Hawaii as Awa. Our guest, Keli'i Kotubetey (Assistant Executive Director of Paepae o He'eia on the island of O'ahu) takes us to an 800 year old site of ancient Hawaiian aquaculture where this fish is being cared for and grown for the future.

The Trispot Darter has a fascinating story of rediscovery, migration, and conservation teamwork. Three guests join the conversation: Fisheries Biologist Cal Johnson (Alabama Department of Environmental Management), Independent Researcher and author Pat O'Neil (formerly with the Geological Survey of Alabama); and biologist Lee Holt with our Alabama Ecological Services Office.

Meet the knifefishes! From the Clown Knifefish to the to the Electric Eel, Katrina and Guy take a broad brush look at this bizarre group of fascinating fishes.
