that is a huge question and would take a book to answer ,
The effects are thousands and different in all places and different at different times of the year as well as the day or the night
low tide =places become dry with puddles ,where fish have laid eggs ,crabs and all sort of edge creatures move around ,and there are many birds .and bird droppings ,the world on the edge has moved down .
High tide ,this place is now covered with water and fish are swimming into this space which is now rich with the garbage the low tide visitors left behind .
There is much life both plants and all the other fish ,birds crabs ,bugs etc that moves with the movement of the tide over the changing bottom
which is wet for a time and then dry with the sun or moon added .both having an big affect on the life that lays below .
The microscopic world here is more intense than any where else in the world .
this is the edge
and edges are the most abundant places for life.
Water and land edges are the richest as opposed to forest and prairie edges,and the sea edge is the richest of all because of the tides
And the effects are not just on the water or ground ,they carry on into the air ,from the land side a current goes straight up into the air ,and on the water side it falls down ,this aerial elevator moves with the tides and you can see birds rising using this current ,or falling quickly to catch a morsel or just riding it flapping their wings to stay in the same place.
Most of the fish and aquatic life on the coast are on this moving edge
and ,most of the life on the land is as well
This phenomena of the abundance of life in action ,on edges is called the EDGE EFFECT
A excellent book to read about this is called sensitive Chaos by Theodor Schwenck,on the Rudolph Steiner press.
go to the beach one day and just look ,and you can write a book yourself about all the things going on ,
At the edge of the sea - called the intertidal zone - tides affect marine life because tides are a form if kinetic energy. Tides (and waves) bring water and food to animals that live in the intertidal zone, and tides take away wastes. The organisms just sit there and the ocean does the work.
Outside the intertidal zone, tides have less effect, except of course they create currents and cause mixing.
The greatest effect of tides on marine life is seen in the intertidal zone - this is the area of the seabed which is exposed at low tide. Animals living in this zone (like mussels, clams, barnacles, worms, crabs, tunicates... the list is huge) are underwater for part of the day but exposed to the air for part of the day as well, so they have to cope with changes in temperature, humidity, desiccation (drying out), predation by animals (such as birds) that can't reach them when they are under water. Animals trapped in rockpools, even though they are still under water, are affected too. The pool can heat up, and evaporation of the water will increase the salinity of the pool. Seaweed in the intertidal also has to deal with being exposed for part of the day - they no longer get support from the water to hold them upright, they can't exchange chemicals as efficiently, they risk desiccation. Hope this helps! Good luck with the report
Probably the greatest effects of tides on sea life are on the creatures that are dependent on tide pools and beaches like star fish, clams, mussels, oysters, even sea weeds. Mammals that come ashore like sea lions and seals are also effected.
