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.
Clownfish are the only fish known to be able to live amongst the tentacles of anemones. The tentacles of the anemones normally sting other fish, but clownfish excrete a mucus over their skin that tricks the anemone into believing it is touching itself, so it does not sting.lownfish are the only fish known to be able to live amongst the tentacles of anemones.
