ST. PETERSBURG, Fla. (AP) — 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.
The National Oceanic and Atmospheric Administration announced what it calls an “emergency response” focused on the Florida Keys starting next week. A NOAA news release called the effort unprecedented.
“If the opportunity presents itself, this would be the first attempt ever to rescue and rehabilitate smalltooth sawfish from the wild,” said Adam Brame, NOAA Fisheries’ sawfish recovery coordinator.
Sawfish, related to rays, skates and sharks, are named for their elongated, flat snout that contains a row of teeth on each side. They can live for decades and grow quite large, some as long as 16 feet (about 5 meters). They were once found all along the Gulf of Mexico and southern Atlantic coasts in the U.S., but now are mainly in southwestern Florida and the Keys island chain as their habitats shrink. A related species is found off Australia.
Since late January, state wildlife officials have been documenting what they call an “unusual mortality event” that has affected about 109 sawfish and killed at least 28 of them. There have been reports of abnormal behavior, such as the fish seen spinning or whirling in the water. Other species of fish also appear to have been affected.
“We suspect that total mortalities are greater, since sawfish are negatively buoyant and thus unlikely to float after death,” Brame said.
Officials haven't isolated a cause. The Florida Fish and Wildlife Conservation Commission reported Wednesday that sawfish necropsies have not revealed any pathogen or bacterial infections, nor problems with low water oxygen levels or contaminants such as chemicals, or toxic red tide. Water testing is continuing.
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.
The wildlife agencies are working with three organizations that will rehabilitate sawfish that are rescued. One of them, Mote Marine Laboratory and Aquarium, 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.
“We have quarantine facilities ready to accommodate rescued sawfish where they would be under observation by qualified personnel under specific care and release guidelines," said Kathryn Flowers, Mote Postdoctoral Research Fellow and lead scientist on the sawfish issue. "Attempts to solve this mystery call for robust collaboration.”
Brame said the effort depends on tips and sightings from the public of dead or distressed sawfish so rescuers know where to look for them. NOAA has a tipline at 844-4-Sawfish and FWC has an email, sawfish@fwc.com.
In recent years, threatened manatees also suffered a major die-off in Florida waters as pollution killed much of their seagrass food source. State and federal officials fed tons of lettuce to manatees that gathered in winter outside a power plant for two years, and the manatee numbers have rebounded some with 555 deaths recorded in 2023 compared with a record 1,100 in 2021.

Tornadoes and violent storms struck parts of the South and Midwest on Wednesday, killing at least one person, knocking down power lines and trees, ripping roofs off homes and shooting debris thousands of feet into the air.
A tornado emergency was briefly issued in northeast Arkansas, with the National Weather Service telling residents on social media: “This is a life threatening situation. Seek shelter now.”
Dozens of tornado and severe thunderstorm warnings were issued in parts of Arkansas, Illinois, Indiana, Missouri and Mississippi as storms hit those and other states in the evening. Forecasters attributed the violent weather to daytime heating combining with an unstable atmosphere, strong wind shear and abundant moisture streaming into the nation's midsection from the Gulf.
The Missouri State Highway Patrol said at least one person was killed Wednesday in southeast Missouri, KFVS-TV reported.
The coming days were also forecast to bring the risk of potentially deadly flash flooding to the South and Midwest as severe thunderstorms blowing eastward become supercharged. The potent storm system will bring “significant, life-threatening flash flooding” each day through Saturday, the National Weather Service said.
With more than a foot (30 centimeters) of rain possible over the next four days, the prolonged deluge “is an event that happens once in a generation to once in a lifetime,” the weather service said. “Historic rainfall totals and impacts are possible.”
More than 90 million people were at some risk of severe weather in a huge part of the nation stretching from Texas to Minnesota and Maine, according to the Oklahoma-based Storm Prediction Center.
A tornado emergency was briefly declared around Blytheville, Arkansas, Wednesday evening, with debris lofted at least 25,000 feet (7.6 kilometers), according to Chelly Amin, a meteorologist with the weather service. That was the weather service’s highest alert, and rare. It was not immediately clear whether there were any injuries.
“It's definitely going to be a really horrible situation here come sunrise in the morning in those areas, coming out of Arkansas,” Amin said.
More than 2 miles (3 kilometers) of Highway 18 in the area was temporarily shut down due to a downed power line.
A tornado was also reported on the ground near Harrisburg, Arkansas, in the evening.
The Arkansas Division of Emergency Management reported that there was damage in 22 counties due to tornadoes, wind gusts, hail and flash flooding. At least four people were injured and there were no reports of fatalities as of Wednesday evening.
In Pilot Grove, Missouri, several structures were damaged, cars flipped over and power poles were snapped, the state emergency management agency said. Minor injuries were reported, according to the Missouri State Highway Patrol. Meanwhile roads were closed because of storm debris and downed utility lines near the town of Potosi, southwest of St. Louis, according to the state transportation department.
Authorities in eastern Missouri were trying to determine whether it was a tornado that damaged buildings, overturned vehicles and tore down utility poles, tree limbs and business signs in the morning in and around the city of Nevada.
Another tornado touched down in the northeastern Oklahoma city of Owasso about 6:40 a.m., according to the weather service office in Tulsa. There were no immediate reports of injuries, but the twister heavily damaged the roofs of homes and knocked down power lines, trees, fences and sheds.
Forecasters at the National Weather Service office in the area of Paducah, Kentucky, took cover during a warning at night.
“We’re all good here at the office, the circulation JUST missed us to the south,” the agency said on social media.
Power was knocked out to nearly 90,000 customers in Arkansas, Mississippi, Missouri, Illinois, Kentucky and Tennessee, according to PowerOutage.us, which tracks outages nationwide. As storms moved through Indiana on Wednesday night, more than 182,000 customers lost power.
News outlets reported part of a warehouse collapsed in Brownsburg, Indiana, a suburb of Indianapolis, temporarily trapping at least one person inside, while the police department told people to not travel through the city. Five semitrucks were blown over on Interstate 65 near Lowell, Indiana, state police reported.
The dangerous weather came nearly two years to the day after an EF-3 tornado struck Little Rock, Arkansas. No one was killed, but there was major destruction to neighborhoods and businesses that are still being rebuilt today.
About 2.5 million people were in a rarely called “high-risk” zone, covering parts of west Tennessee including Memphis; northeast Arkansas; the southeast corner of Missouri; and parts of western Kentucky and southern Illinois.
The Storm Prediction Center said “multiple long-track EF3+ tornadoes" were likely. Tornadoes of that magnitude are among the strongest on the Enhanced Fujita scale, used to rate their intensity.
At a slightly lower risk for severe weather was an area that included Chicago, Indianapolis, St. Louis and Louisville, Kentucky. Dallas, Detroit, Milwaukee and Nashville, Tennessee, were also at risk.
A line of thunderstorms dropped heavy rain through parts of Indiana on Wednesday night. At least one street was flooded in Indianapolis, with water nearly reaching the windows of several cars, according to the city's metropolitan police department. No one was in the vehicles.
Additional rounds of heavy rain were expected in parts of Texas, the lower Mississippi Valley and the Ohio Valley from midweek through Saturday. Forecasters warned that they could track over the same areas repeatedly, producing dangerous flash floods capable of sweeping cars away.
Middle Tennessee was looking at severe storms followed by four days of heavy rains as the front stalls out and sticks around through the weekend, according to NWS meteorologist Mark Rose.
“I don’t recall ever seeing one like this, and I’ve been here 30 years,” Rose said. “It’s not moving.”
Rain totaling up to 15 inches (38 centimeters) was forecast over the next seven days in northeastern Arkansas, the southeast corner of Missouri, western Kentucky and southern parts of Illinois and Indiana, the weather service warned, with some areas in Kentucky and Indiana at an especially high risk for flooding.
In Michigan, crews worked to restore power after a weekend ice storm. More than 122,000 customers were still without electricity on Wednesday, according to PowerOutage.us.
The Mackinac Bridge connecting Michigan’s Lower and Upper Peninsulas was shut down because large chunks of ice were falling from cables and towers. It was the third consecutive day of bridge interruptions from the ice storm.
