In a video that premiered at the National Association of Biology Teachers meeting in California, “The Birth and Death of Genes,” Professor William Detrich (right) explains genetic changes that cause antarctic ice fish to lose the ability to produce hemoglobin. The icefish is an unusual fish found in Antarctica that is able to survive in some of the coldest waters on earth.
Professor Detrich and a team of 30 scientists from around the world were on board the Nathaniel B. Palmer research vessel for the ICEFISH (International Collaborative Expedition to Collect and Study Fish Indigenous to Sub-Antarctic Habitats) 2004 Cruise. The mission of the 61-day cruise, which left from Punta Arenas, Chile, on May 17th, and docked at Cape Town, South Africa, on July 17th, was to collect specimens of lower latitude fishes in order to relate the evolution, physiology, biochemistry, and population dynamics of high latitude Antarctic fishes of the suborder Nototheniodei to the transitional fish fauna of the subAntarctic.
