Primary Predators
* Orcas (Killer Whales): The most significant threat, especially where orca populations are high.
* Great White Sharks: Occasional predators where ranges overlap.
* Other Sharks: Salmon sharks and leopard sharks may prey on sea otters less frequently.
Bigger Threats Than Predation
Sea otter populations are more often limited by habitat loss and degradation, disease, and pollution than by predators. Humans also impact them through fishing practices and oil spills.
While sea otters have a few predators, they are not a primary food source for any animal. Their vulnerability comes more from human activity and environmental factors.
