This image provided by NOAA shows a smalltooth sawfish. Endangered smalltooth sawfish, marine creatures virtually unchanged for millions of years, are exhibiting erratic spinning behavior and dying in unusual numbers in Florida waters. Federal and state wildlife agencies are beginning an effort to rescue and rehabilitate sawfish to find out why.
“We suspect that total mortalities are greater, since sawfish are negatively buoyant and thus unlikely to float after death,” Brame said. It's also not clear if the deaths and odd behaviors are related to a lengthy summer heat wave in Florida waters experts say was driven by climate change. The superheated waters caused other marine damage, such a coral bleaching and deaths of other ocean species., said in a news release that even relatively small numbers of sawfish deaths could have a major impact on the population, listed as endangered since 2003.
