Scientists Urge Public to Report Whale Shark Sightings

Jun 8, 2018

In a rare sighting last weekend, boaters spotted multiple whale sharks off the coast of Anna Maria Island.

That has grabbed the attention of scientists at the Mote Marine Laboratory and Aquarium in Sarasota, who are now asking the public to report other sightings.

Jacob Campoamor took photos and recorded video of the sharks. He said his family was fishing for grouper 40 miles off the coast when he first spotted them.

Campoamor says all of the animals were bigger than the 26-foot-long boat they were on.

“We've seen dolphins and we've seen manatees and giant sea turtles. Never seen anything like a whale shark,” he said.

Robert Hueter, a scientist who runs Mote’s Center for Shark Research, said they have tracked down and tagged hundreds of whale sharks off Mexico's Yucatan Peninsula.

They have then monitored those sharks regularly moving throughout the Gulf of Mexico, but they generally avoid visiting Florida’s west coast.

He thinks this may be a consequence of one recurring event.

“Something I've speculated, without any real data, is that because this is an area that does experience red tide from time to time and red tide would not be something that would not be friendly to a whale shark that's a filter feeder,” Hueter said. “Maybe they’ve just evolved to stay away from this part of the Gulf.”

Hueter said once his team tracks new whale sharks down, they will tag them for research and then release them. The tags monitor the sharks’ migration over six months.

Mote scientists last spotted whale sharks in 2010 near Sarasota.  

Mote is asking the public to report sightings to Hueter at 941-302-0976. They asked to call from their boat or within 24 hours after disembarking.
