Killer whales can dive as deep as 30 meters during hunting. Rot and decay of orca teeth is but a symptom of a far more menacing threat to orca in captivity.

Over the last few decades, as wild orca research has expanded, researchers have described different forms or types of orcas. Keto, a 21-year-old SeaWorld orca and the oldest at Loro Parque.

Although orcas have acted aggressively toward humans in the wild, it’s generally not at humans if that makes sense. Orcas tend to bite down on the fences that separate orcas during performances which leads to fractured teeth. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. Orcas can develop broken teeth in captivity.

Though he's still young by wild orca standards, his teeth have been decimated in captivity. The teeth of Killer whales can be up to 3 inches long, and some even longer. Not only are orcas much bigger, they are also smarter. But in years where the orcas make an appearance, which they did in 2009, 2011 and 2013, that number drops by 62 percent from the previous year. ... especially when the Orca is attempting to drag the human using its teeth. These teeth also display a slight rose pattern in the cross section of dentine. Although it’s a gradual process, some populations and eco-types are more susceptible to tooth … Orcas can live for decades, and as this new study shows, the compromised condition of orca teeth make them poor candidates for release back into the wild.

However, due to the handling of prey, wild orca teeth can become worn and degrade over the course of numerous decades. Captive killer whales have severely damaged teeth, something that is likely causing them pain and could prevent them from ever being released into the wild. Orcas tend to bite down on the fences that separate orcas during performances which leads to fractured teeth. Orcas can develop broken teeth in captivity.

Just like us, killer whales … Killer whale teeth are also cone shaped, have enamel at the ends, are covered by cementum and have round or oval cross sections of dentine. An example of wild orca teeth Photo via TheOrcaProject.

When she was captured, the orca had a complete healthy set of pointed teeth, as is normal for wild orcas. These diseases lower the orca's quality of life and can lead to the public receiving misinformation about the life span and health of orcas.

For the seals it can be a win-win situation. Although it’s a gradual process, some populations and eco-types are more susceptible to tooth … SeaWorld’s orca — the inimitable ambassadors of the marine theme park’s captive cabaret where “wild” is but an illusion — face an unhealthy state of decline much like the industry itself. Although the great white shark has a fearsome reputation, in a straight fight it is outclassed by the orca.

This largely contrasts with orcas in the wild, who show little to no tooth wear.

There’s only been a single report of a wild orca attacking a human, and that may well have been a case of mistaken identity as the person attacked was surfing at the time. Killer whale teeth in the wild generally do not suffer severe wear at the tip (and only very rarely exhibit breakage) and when they do, this wear occurs at the population level and is associated with prey type (e.g., in the northeastern Pacific offshore ecotype, severe tooth wear is associated with feeding on sharks; Ford et al.

Killer whale teeth also have two slight external indentations and they are smaller than sperm whale teeth. These diseases lower the orca's quality of life and can lead to the public receiving misinformation about the life span and health of orcas. This condition is rarely seen in orcas in the wild. Usually, fatal attacks involve the staff rather than public, although in 1999 a trespasser named Daniel Dukes, gained access to the Orca enclosure after the park had closed.

As of this past April, several of her front teeth were nearly missing from the wear and damage occurred in captivity.

Known as ecotypes, these distinct types of orcas differ in size, appearance, prey preferences, foraging techniques, dialects, behaviours, and social groups.

Due to the exposed gums, infectious diseases have a direct entry to the bloodstream and can reach vital organs such as the kidneys and heart.

In the wild, orcas have been seen preying on great white sharks. Damaged orca teeth, chipped, broken, drilled and worn to the gums.

The killer whale, or orca (Orcinus orca), is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Great whites are now known to be warm blooded but orcas still have much higher metabolic rates because they breathe air. Killer whales ‘speak’ to each other using distinct clicks and whistles. Orcas can live for decades, and as this new study shows, the compromised condition of orca teeth make them poor candidates for release back into the wild.
