A killer whale of a tale: when peer review sometimes fail - Loro Parque Tenerife
Loro Parque response^
It's worth noting that the people responsible for this "study" are by far the least objective people on this subject. Jett and Ventre themselves made a study previously and made the claim that orcas live substantially shorter lives in that study. To keep things short, their study included stillbirths, miscarriages, and neonate mortality, things that no survey of wild orca lifespans could possibly include. Ingrid Visser also once tried to claim a 3 year old orca was an infant orca who was too depressed to feed. So keeping all these things in mind, this study,and their claims about toothaches, is highly suspicious at its best.
