Pygmy Killer Whale Patient Dies

Dallas, a pygmy killer whale undergoing rehabilitation at Mote Marine Laboratory’s Dolphin and Whale Hospital in Sarasota, died on Sept. 3.

Dallas had been treated for a number of conditions including digestive problems and lung issues including pneumonia since arriving at the hospital on June 16 of this year.

Preliminary results from a necropsy indicated that the cause of death was likely toxic pneumonia, a condition that can be fatal in as little as 12 to 24 hours. According to the facility, additional test results will have to be reviewed before a final conclusion can be reached.

“There is so little known about the disease processes and biology of many animals cared for at our hospital,” said Mote’s Chief Veterinarian Dr. Charles Manire in a press release, “even with constant improvements with medical equipment and treatments, these animals are still wild animals that must hide symptoms very well out of necessity.”

Dallas had been exhibiting typical behaviors including feeding, swimming and socializing with the other animal just before he died on Wednesday evening. The pygmy killer whale had arrived at the hospital on June 16 with another adult male pygmy killer whale, nicknamed Pete, after they were both found near Boca Grande. By reviewing the results of the necropsy, the facility hopes to prevent similar issues with Pete. Mote’s Dolphin and Whale Hospital will continue to monitor Pete around-the-clock.
