In between the euphotic and the bathyal zone is the twilight zone, an area that still receives some sunlight, but not enough for plants to grow. The bathyal zone (aka midnight) is the middle zone that has no light. Many zooplankton and smaller fish live here.he euphotic zone is from the surface of the ocean down 200 meters. This zone is also sometimes called the sunlight zone because there is enough sunlight to have photosynthesis. This zone has the highest levels of sunlight, photosynthesis, and dissolved oxygen. Many large predatory fish live here.
Tidal Zones. There are four commonly recognized tidal âzonesâ based on exposure during tidal periods, wave action and shoreline features. The presence or absence of water, temperature, wave action, variation in salinity (saltiness), exposure to light, and other factors determine what organisms are able to live happily in each zone. In general, physical factors, especially exposure to drying, limit how far up on shore an organism can live.
