Their smooth and streamlined bodies make sea lions efficient hunters of fish (especially sardines) and other prey. Research has revealed that Galápagos sea lions can make the longest, deepest dives of all the sea lion species – they can dive for over 10 minutes and reach depths of almost 600m!

What can a sea lion do?
Sea lions are strong swimmers can reach speeds of nearly 20 miles per hour in the water. They swim using their long foreflippers to generate power and their hind flippers to steer. Sea lions hunt underwater and can dive to depths of 300 meters.
Why are the Galapagos sea lions important?
Galápagos sea lions and fur seals are endemic pinnipeds to the Galápagos Islands, where these two species play a crucial role as key predators and sentinel species for the functioning, services, and health of the marine ecosystem (Alava and Salazar, 2006; Alava et al., 2014, 2017a).
What are sea lions diving for?
When you see an odd group of dark “fins” sticking out of the water in California harbors, it is usually sea lions sticking their flippers into the air to cool off. A sea lion's sleek body is perfect for diving deep in the ocean (up to 600 feet, or 180 meters) in search of tasty fish and squid.
Are sea lions important?
The proximate role played by seals and sea lions is obvious: they are predators and consumers of fish and invertebrates. ... Others may play a structural role by influencing the physical complexity of their environment; or they may synthesize the marine environment and serve as indicators of ecosystem change.
Do sea lions have bad breath?
Hooker's Sea Lions are number 7 on The Most Extreme Stinkers. Their breath smells bad enough to kill a human. If you want to smell like a Hooker's sea lion, all you have to do is stop brushing your teeth.
How has the Galapagos sea lion adapted?
Thick, oily fur and a layer of blubber enables sea lions to retain a high body temperature in frigid waters. A special process called thermoregulation also allows sea lions to keep warm. Thermoregulation occurs because the blood vessels on a sea lion's flipper are exposed as they are not covered by blubber or fur.
How do Galapagos sea lions defend themselves?
Their biggest defense to this is to get to the edge of the water and onto land. Sometimes these predators can jump up and still capture them though if they don't move far enough away from the edge of the water.
What eat Galapagos sea lions?
The main predators of Galapagos Sea Lions are sharks and killer whales. Dogs are also known to prey upon pups.
How do sea lions not get cold?
A sea lion often regulates its body temperature by lifting and exposing one or more flippers. The blood vessels just under the skin dilate and absorb or release heat to the environment. One of the ways sea lions keep themselves cool is by spending long periods in the water.
How do sea lions keep warm?
Sea lions have unique adaptations that allow them to maintain their high body temperature while swimming around in icy water. The first of these is a thick blubber layer, which is approximately an inch thick. Covering that blubber is tightly packed fur. ... These layers help keep the body heat in.
How do sea lions see underwater?
Its believed that they can see colors on the blue and green spectrum, but with increased light sensitivity they can get more light underwater. ... Except in the case of sea lions, their natural eye is what they use underwater: they use their nictitating membrane on land to protect from sun and sand.
What would happen without sea lions?
If the Steller sea lion isn't around to eat the easiest catches in the ocean, diseases will be past down genetically. More lame ones will be born and fisheries will be catching lame fish. Extinction might cause damage to the sea and sea life.
What are 3 things we can do to protect sea lions?
Eat from local restaurants that are part of the Aquarium of the Bay's Seafood Watch Alliance. Reduce the toxins you use on your lawn and garden, as these chemicals end up in our waterways. Bring your own reusable canvas or cotton shopping bags to carry your purchases. Reuse paper or plastic bags to help reduce trash.
What is the Lions role in the ecosystem?
Lions are carnivores and have no natural predators besides man, which makes them apex predators or keystone species. They cull populations of herbivores and smaller carnivores through predation. Without lions, some creatures would overpopulate.
