The Infralittoral

The infralittoral zone begins at the lower waterline, which means that it encompasses the permanently submerged area of the coastal benthal. It extends down to the depth at which light-loving species…

The Eulittoral

The eulittoral is the tidal zone; it is defined as the area between the upper and lower waterlines (mean high and low waterlines). In areas with strong tides, especially in mudflats, the eulittoral i…

The Supralittoral

The supralittoral is the splash zone, which ist not submerged permanently, but reached by the waves and the spray. It begins at the mean high-water line (the average water level at high tide) and ext…

Bivalvia

The Bivalvia belong to the phylum Mollusca, together with the snails and cephalopods (octopuses, squids) and some smaller groups such as the chitons and the tusk shells. Around 8,000 species have bee…

Der Frühling ist da: Der Wein treibt aus… …im Weinfeld blüht der Mohn… …Schmetterlinge flattern umher… …Bienen besuchen die Birnbaumblüten… …und überall blüht es. Und die Vögel z…

Marine snails – Introduction

The snails, or gastropods, belong to the same phylum as bivalvia (e.g. mussels), cephalopods (e.g. octopus and squid) and some smaller groups such as chitons and tusk shells, i.e. the phylum Mollusca…

Corals

Corals belong to the class of anthozoans (Anthozoa), together with the sea anemones. These form the phylum Cnidaria together with the hydrozoans and the jellyfish. Cnidarians are a ‘lower’ group of a…

Chitons

The phylum of molluscs comprises several classes, among which the bivalvia (mussels), the snails and the cephalopods (octopuses, squids) are the most important and best known. However, to the mollusc…

Life between the algae

Benthic algae, i.e. algae that are attached to the substrate, provide a habitat for countless animals. Since most of these species are quite small, you have to make an effort to spot them. Many can o…

Ascects of the evolution of the algae

The first living organisms on Earth were bacteria (and archaea, a now rather rare and still little-researched bacteria-like group that differs significantly from both bacteria and eukaryotes (i.e. pl…

Algae

Algae do not generally have a particularly good reputation. When it comes to algae, most people think of killer algae, toxic algal blooms or simply slippery, bone-breaking, ugly coatings on wet rocks…

Fish

When it comes to marine animals, most people naturally first think of fish: these are known to everybody and of the greatest importance to us as a source of food. Due to its low content in nutrients…

Organisms living in stone

Apart from the numerous plants and animals that grow on the rocks in the sea, some organisms live inside the rock. Understandably, these are rarely visible while they are alive, but you can find thei…

Sponges

Sponges are very unusual organisms. They belong to the animal kingdom, but in some respects they are more like plants, for example they are sessile (attached to the substrate), their shape is not sym…

Sea cucumbers

Sea cucumbers do not look particularly attractive; they are in fact rather ugly and appear boring and uninteresting. Nevertheless, these animals play a very important role in the marine ecosystem and…

Sea anemones

On the rocks in shallow water in the small bays near Azalás, it is easy to find some particularly beautiful and interesting representatives of marine fauna: the sea anemones. The order of sea anemone…

Gastropoda 6: Worm snails

Among the many strange creatures of the intertidal zone are the worm snails. These snails only crawl around freely while they are young, then they attach themselves to the substrate and adopt a sessi…

Barnacles

Seeing barnacles on a rocky coastline one would hardly think that they are close relatives of crabs and lobsters. However, they belong to the Crustacea, and together with the Goose barnacles and some…

The Zones of the Mediterranean Sea

The marine ecosystem is divided into a number of zones with different environmental conditions. To begin with one must distinguish the seabed, known as the benthal, and the water column, known as the…

The demands of the sea on its inhabitants

Life in the sea places significantly different demands on organisms than life on land. First of all, of course, there is an unlimited supply of water. All organisms need water – they consist largely…
