X-Band radar systems are able to resolve multiple wave systems, e.g. swell and wind sea systems. Usually, swell is characterized by its phase speed: Swell waves propagate faster than the wind, where as wind driven waves can not travel faster than the wind that generated these waves (see also waves).
There are 28 known species of anemonefish, most of which live in the shallow waters of the Indian Ocean, the Red Sea, and the western Pacific. They are not found in the Caribbean, Mediterranean, or Atlantic Ocean. Surprisingly, all clownfish are born male.
Giant Pacific octopus spend most of their lives alone. They live in chilly (60 degrees Fahrenheit or colder) Pacific waters from Korea and Japan north to Alaska and south to Southern California. They live in fairly shallow, coastal waters down to depths of 330 feet or more.
