The answer is letter D or 2. Sea lions are sea mammals that can walk on land and swim in the ocean. They have a lifespan of about 20 to 30 years. A male sea lion weighs about 300 kilograms and can grow about 2.4 meters or 8 feet long while a female sea lion weighs about 100 kilograms and can grow up to 1.8 meters of 6 feet long.
Sea lions have a torpedo shaped torso and flattened powerful flippers they use when they are in the water. Even though they spend most of their time in the water, they sometimes spend time on land – this is where they differ from seals because seals typically just lay out on the sand while sea lions can lift their bodies and walk on all fours.
