We may think that the toughest place would be one with enough pressure to crush your bones or somewhere without a bite or somewhere where is too hot to survive without vaporising.
But for many creatures the toughest place is one without a secure medium that rushes with the waves and crushes with the coastline rocks.Is the inter-tidal zone, a place where the sea level rises and drops in a regular basis and where little oxygen is to be found.The few fishes that live here do partially breathe air from the surface.Many of the creatures from deeper waters wouldn't survive the waves and the loss of oxygen and would parish.Invertebrates here move slowly and have tough armour to be protected from the waves.They take the advantage of mineral exchange from deeper water to obtain nutrients.In low tide creatures are trapped in rock polls that work as a temporal ecosystem separated from the sea.
