A brief introduction to rocky shore s and their biota.

The animal populations on the rocky shore are dominated by invertebrates such as barnacles, mussels, oysters, tubeworms, limpets, chitons, snails, crabs and starfish. Barnacles, mussels, and oysters are all stationary filter-feeders. They obtain their food by filtering for phytoplankton and edible particles straight from the water above them while they are submerged beneath the tide.

The distribution pattern on the Rocky Shore is zonation. Zonation is the distribution of organisms into different zones. Zonation is created and occurs due to the tidal movements of water. Different species live in different tidal zones on the rocky shore due to different adaptations toward desiccation and exposure to the sun.

The intertidal rocky shore of Caloundra Beach is inhabited by diverse range of biodiversity of animals and plants, many of which have developed high levels of adaptations throughout their existence. The very boundary of marine and terrestrial ecosystem, this environment.A brief introduction to rocky shore s and their biota. Prepared by Jennifer Coughlan and Tasman Crowe. School of Biology and Environmental Science, University College Dublin. A rocky shore is an intertidal area of the coastline consisting mainly of solid rock. Rocky shores are very much a boundary zone between terrestrial and marine habitats and therefore represent sharp environmental.


The 5 major zones of a rocky shore are the Supra-littoral zone, Upper littoral, the middle littoral zone, the lower littoral zone and the sub-littoral zone. Each zone contains its own distinctive indicator species which allow us to identify different regions with more accuracy. The indicator species which were found in our research were Nodular Periwinkle, Blue Grey Periwinkle, 6 plated Acorn.The best time to explore a rocky shore is at low tide, when there is a fairly calm sea, so as to avoid those sudden big waves. For this reason, we started our fieldwork on Shek O rocky shore at 3 p.m. to avoid the high tide and the tidal information was checked out from the Hong Kong Royal Observatory.

Rocky-shore bioerosion assemblages are typified by the Trypanites Ichnofacies characterized by the presence of deep-tier dwelling borings produced by a variety of invertebrates (sponges, worms, bivalves, cirripedes, and echinoids) seeking refuge from hostile conditions and predators. Two clearly distinct recurrent assemblages can be recognized when analyzing trace-fossil associations in rocky.

The rocky shore is one of the best-studied marine ecosystems, and many of the earliest discoveries about marine ecology were made by scientists who study the complex marine communities that live in this system.
