Tell me what the five largest ocean animals are. Place in a numbered list from largest to smallest, please.
The five largest ocean animals from largest to smallest are:

1. Blue Whale -- These whales can weigh nearly 200 tons and get up to 100 feet long with hearts that way as much as a car.
2. Fin Whale -- This whale species is called the greyhound of the sea and has stomachs that can eat over 4,000 lbs. of krill.
3. Whale Shark -- As the biggest fish in the world, whale sharks can be almost 40 ft. long and weigh nearly 20,000 pounds, but are considered gentle giants.
4. Sperm Whale -- This type of whale has the most prominent head and giant brain and can hold its breath for two hours.
5. Giant Manta Ray -- This ray has a wingspan of almost 30 feet and is very smart, graceful, and gentle.
