Aquatic Predators 

Washington State is known for its beautiful waterways, but what lurks in the depths of these ecosystems can be deadly. Aquatic predators such as alligators and sea lions pose a severe threat to humans and wildlife alike. 

In this section, we’ll delve into the details of the predators found in Washington’s waterways, their hunting patterns, their physical abilities, and what precautions to take when swimming or boating in areas where these predators are common.

While alligators are more commonly associated with the swamps of the southern United States, they can also be found in Washington’s waterways. These giant reptiles are known for their sharp teeth, strong jaws, and incredible power. 

If you’re swimming or boating in areas with alligators, you must be aware of their hunting patterns. Alligators are most active at dawn and dusk and can often be found near the edges of waterways where they can ambush their prey. They can move quickly and silently in the water, so keeping a watchful eye and steering clear of large objects is essential. 

Sea Lions

If you’re swimming or boating in areas with sea lions, it’s important to be cautious and stay at a safe distance. Sea lions are curious animals and may approach boats or swimmers out of curiosity. 

It’s important to avoid feeding them and to keep all body parts, such as hands and feet, out of the water. 


You can take a few precautions when swimming or boating in areas where aquatic predators are common. First and foremost, it’s essential to be aware of your surroundings and keep a watchful eye for any signs of predators.
