SARASOTA, Fla. -- Two more dead bottlenose dolphins have been recovered amid southwest Florida's red tide outbreak, bringing the total to 11 since last Tuesday.

Mote Marine Laboratory and Aquarium's Stranding Investigation Program recovered the dolphins Sunday morning, according to Hayley Rutger, its content development manager.

The 11th dolphin was a 12-year-old named Speck, who was being tracked since birth by the Sarasota Dolphin Research Program. He spent most of his time in the area of Siesta, Casey and Lido keys and had been documented more than 340 times, according to the group.

Necropsies are ongoing or will be conducted on all the animals to figure out their cause of death. The toxic red tide appears to be the leading candidate, however, having already killed thousands of fish, manatees, sea turtles and other marine life in recent weeks.

Venice Police Officer Paul Joyce serves on the agency's marine unit and last week told 10News every time he sees his phone ring or he gets a text from a rescue group, "My heart rate goes up my blood pressure goes up."

Mote asks people who come across injured or dead marine life to contact authorities. They also host an interactive map of user-generated condition reports.

Earlier: Toxic algae to persist, move southeast from Pinellas County — for now

The latest red tide forecast by the Florida Fish and Wildlife Conservation Commission reports water should continue moving southward, meaning places ravaged by red tide will continue experiencing it.

Pinellas County beaches that have yet to measure any considerable concentration should see the situation improve some in the meantime.
