Animals in Rocky Shores
Rocky Shores consist of 3 main parts • The rock crevices in the splash zone and the upper shore of the littoral zone • The middle shore and lower shore of the littoral zone • The sub-littoral zone
Zonation Different parts of the Rocky shores have different environment condition. Therefore, different animal have different abilities to survive in different parts of the rocky shore, resulting in zonation.
The rock crevices in the splash zone and the upper shore of the littoral zone only filled or covered with water for a few hours each day. Animals live in there able to withstand the relatively dry and high temperature condition.
Periwinkle and Acorn barnacle are the examples of animals living in there.
The middle shore and lower shore of the littoral zone are covered with sea water half the time. Animals usually feed and breed there during high tides.
The organisms found are mainly barnacles, limpets, chitons, rock oysters, mussels and crab
The sub-littoral zone is always submerged. Therefore, it is suitable for animals with limited abilities to withstand desiccation.
Sea cucumbers, sea urchins, shrimps and small fishes can be found in there.
