The 2-1/2 year-old female Orca that died on Monday was the second killer whale to die at the San Antonio facility. The other one, a 14 year old male, died last October.
An necroscopy will take four to six weeks. In the meantime, we can speculate.
- A disease or some other pathological cause, e.g. genetic defect.
- Trauma -- from another whale or from a self-inflicted injury.
- A toxicological cause, chemical or environmental. Toxic habitat.
- Depression. She was rejected by her mother and was, after all, a captive animal.
- Foul play.
Two dead whales in less than a year at the same location. I'd say that was something to look into.
