TESTIMONIALS America’s Crayfish: Crawling In Troubled Waters "Rarely is a science video as artistically and beautifully produced as this introduction to crayfish." Best Of Editors’ Choice 2000 — Jan 2001 Issue — BOOKLIST "This informative presentation explains the importance of crayfish to the ecosystems they inhabit and why biologists are concerned with their future, and should therefore be of special interest to nature lovers, environmentalists, and fishing fans. Recommended. — J. McDaniel July-August 2000 Issue — VIDEO LIBRARIAN "Anyone who thinks crustaceans are boring should view this fascinating, exceptionally well crafted, beautifully videotaped introduction to the life cycle of the crayfish." — James Scholtz July 2001 Issue - BOOKLIST "I just received my DVD of America's Crayfish: Crawling In Troubled Waters. It is very nicely done and I think my 4th graders will really enjoy it. In the spring, we study the FOSS science unit: Structures of Life (bean sprouts and then crayfish). This is really a highlight of the year and kids do get very attached to "their" crayfish. I usually buy some Cajun Crayfish (pre-cooked) from a grocery store so they can taste them at the end of the unit. (Teachers freeze them at the end of the unit, or the custodian takes them home and eats them ;) We do have crayfish in the streams here in eastern Washington state, and sometimes kids catch them and bring them in to compare with the ones we buy from a distributor in the south. I will recommend this DVD to other teachers in the district because I think the information is really interesting for kids and easy to understand. Thank you." Gayle Talbot., 4th Grade Teacher
