Marine Mammals:
The biggest creatures in the sea are whales, which are mammals not fish. The blue whale is the largest creature that has ever lived. Whales spend all their lives in the sea, but there are other mammals that spend most of their time in water and some time on land, These include sea lions and otters.
Biggest Marine Mammals:
1. The Blue whale is 33.5m (110 ft) long and weighs 130.0 tonnes.
2. The Fin whale is 25.0m (82 ft) long and weighs 45.0 tonnes.
3. The Right whale is 17.5m (57.4 ft) long and weighs 40.0 tonnes.
4. The Sperm whale is 18.0m (59 ft) long and weighs 36.0 tonnes.

Smallest Marine Mammals:
1. The Marine Otter, which lives off the western coast of South America is the smallest marine mammal. It weighs up to 4.5kg (10 lb) and is about 1.15m (3.77 ft) long. The Sea Otter of North American coasts is slightly larger.
2. Small dolphins include Hector's dolphin, which lives off New Zealand. It is rarely more than 1.5m (3.77ft) long and 57.2kg (126 lb) in weight.

Top Food Fish:
Fish and Shellfish are popular foods worldwide. Nowadays, more is specially reared by aquaculture (fish farms) than by capture (using traditional fishing lines and nets).

Big Fish:
Whale Sharks are probably the biggest fish in the world. They are usually up to 12m (39 ft) long - though one caught off Thailand in 1919 was reckoned to be 18m (59 ft) long.
Whale sharks eat only Planktons - tiny plants and animals that float in water. Basking sharks also eat plankton, but most other fish hunt.
1. Whale Shark - 21,000kg (46,297 lb)
2. Basking Shark - 14,515kg (32,000 lb)
3. Great White Shark - 3,314kg (7,306 lb)
4. Giant Manta - 3.000kg (6,614 lb)
5. Beluga - 2,072kg (4,568 lb)
6. Sharptail Mola - 2,000kg (4,409 lb)
7. Ocean Sunfish - 2,000kg (4,409 lb)

Deep Sea Divers:
1. Emperor penguins sometimes dive to depths of 265m (870 ft).
2. In 1989 a leatherback turtle fitted with a depth-gauge reached a depth of 1,200m (3,937 ft).
3. Sperm Whales regularly dive to 1,200m (3,937 ft) and experts think that they may sometimes go down to twice its depth.
4. Fish called "Brotulids" are the deepest-living vertebrate animals. They have been found in deep-sea trenches at 8,300m (27,230 ft) - that is almost as deep as Mount Everest is high!
