Define and explain why estuaries are so important. What is the most common form of marine life found ...

An estuary is an area where freshwater meets and mixes with saltwater. Estuaries have varying degrees of salinity,
depth, and temperature. They serve as a very important breeding area and provide safety to many forms of marine
life. The most common marine life in an estuary are oysters, clams, lobsters, crabs, and shrimp.

Modern whaling techniques consist of a factory ship to process the whale meat, a fleet of catcher boats to locate
and kill the whales, and buoy boats to bring the whales back to the factory ship.

The whale is a seasonal breeder. It migrates to the equator for mating. The female carries her young for 10 to
12 months and will nurse it for 7 months after birth. It travels in herds.

ShrimpThe life cycle of the shrimp involves the female laying the eggs in the ocean, the young moving close
to shore to live, and at 5 to 7 months old, moving back to deep water for breeding.
 OysterThe oyster sprays her eggs in the water. The young oyster or spat hatches within 10 hours where it
will attach to a rock. It stays its entire life on the same rock.
 LobsterThe lobster carries her eggs under her tail. Every 2 years, she lays her eggs by shaking them from
her tail. The young lobster drifts for 3 to 5 weeks before it sinks to the ocean floor to spend the rest of its life.
