Salisbury, Md. - The Salisbury Zoo is mourning the loss of one of its black-handed spider monkeys, Dweasal. Dweasal, age 7, died September 11.

During morning animal checks at the Salisbury Zoo on September 9, animal care staff found that spider monkeys Rozindi and Dweasal had fought overnight. Both monkeys had wounds on their hands and feet, with Dweasal's injuries being significantly worse.

Due to the nature of the injuries, medical intervention was required for Dweasal, and surgery was scheduled for September 11. Dweasal was brought to the Ron Benton Animal Health Clinic at the Zoo for treatment.

While under anesthesia, he began to experience complications, which led to cardiopulmonary arrest. Veterinary staff provided CPR for more than an hour to try to save him.

A full necropsy (animal autopsy) was performed. The necropsy revealed a bite wound to Dweasal's skull. That wound and the consequential swelling from the trauma are most likely why he did not do well under anesthesia.

"This loss has been incredibly devastating for the staff," said Salisbury Zoo Director Chuck Eicholz. "No animal death is easy, but one so traumatic as this takes a huge mental toll on animal care and vet staff. We know the whole community will grieve the loss of Dweasal with us." 

Eicholz recognized Registrar Jessica Mandelson and the animal care team, who have gone above and beyond to care for the spider monkeys.

Rozindi, Dweasal's brother, is still on exhibit. Visitors may hear him vocalizing more often. Animal care staff are observing Rozindi and increasing his enrichment, training sessions, and social time.

The Salisbury Zoo has been in contact with other zoos to find new companions for Rozindi and wants him to be alone for as short a time as is possible.In the wild, spider monkeys live in social groups, and it is important to their well-being to live in social groups while in human care. 

The social dynamic between Rozindi and Dweasal was closely monitored by staff.

Though male spider monkeys will sometimes fight, the monkeys had not fought in almost a year and there were no signs of aggression in the days leading up to this incident. The Salisbury Zoo is looking at bringing in female monkeys, and with any new monkey, there will be an extensive introduction period.
