There are three divided zones in the ocean. They are: the sunlight zone (the topmost layer closest to the surface where fish like jellyfish live [from the surface to 600 feet deep]), the twilight zone (the middle layer where it is not too dark, not too light and a bit like the light at twilight; also where most of the creatures live [from the end of the sunlight zone to 2000 feet deep]) and the midnight zone (the bottommost layer where it is so dark like midnight and bare, only fish with natural lights like anglerfish can survive because there is not much food there and there is hardly any light to see with, the only light available is from the fish [from the end of the twilight zone to the seafloor]).
The Intertidal zone, Coastal Ocean, and the Open Ocean
he Epipelagic Zone is the first layer of the ocean. It's the zone that extends from the surface to 200 meters in depth. In this zone there is the most light and where there is sun there is heat. This is also the most clear zone.The Mesopelagic Zone is the second zone of the ocean layers. Extending from 200 meters to a 1000 meters. In this zone there isn't almost any sunlight that penetrates these depths. It's also called the Twilight zone or the Middwater zone, most of the deep sea fishes are living in this zone.The Bathypelagic Zone is also called the dark zone. In this zone there isn't any sunlight, but you can find light that is produced by deep sea animals like the Firefly Squid or the Vampire Squid. This zone extends from 1000 meters to 4000 meters where the pressure is so high that only a few deep sea animals can handle the pressure. The animals that live on these depths are mostly specially adapted creatures and they have a very different appearance then normal fishes.The Abyssopelagic Zone, this zone is very cold and it almost doesn't contain any lifeform. It's also called the abyss, what actually means no bottom in Greek. The animals that live here are mostly invertible like tiny sea animals. This zone extends from 4000 meters to 6000 meters! The pressure is too high for many deep sea animals.The Hadalpelagic Zone or Hadal zone, the last zone of the ocean layers extends from 6000 meters to the deepest bottoms of the oceans! The deepest spot can be found at the Mariana Trench of the coast of Japan that has a depth of more then 10.900 meters. The pressure here is just amazing and still there are creatures like the Viperfish and the Angler fish that can live on these depths. Animals that live on these depths die if they go to a zone with a lower pression.
Yes, some reefs are exposed at low tide, especially extreme low tide. This puts a strain on coral, and some experience periodic bleaching in the warm water/sunlight. Source: experience with the reefs in my home town of Darwin in northern Australia which experiences extreme tides. During the low spring tide it is possible to walk out on top of the reef and look at the exposed colourful coral, anemones, sponges and other reef life. I am sure that there is only a rather limited subset of species which can survive in this zone as opposed to permanently underwater.
Intertidal Zone
The intertidal zone is good because there is plenty of light for algae and those creatures that depend on algae.

No, the intertidal zone is not in the bathyal zone. The intertidal zone is the area between high and low tides on the coast, while the bathyal zone is a deep-sea zone beginning at about 200 meters below the surface of the ocean.
I be live one of the most uncommon omnivore in the intertidal zone is a sponge
