Most of the islands are found in the Aegean Sea and are divided into seven groups (from north to south): The Northeastern Aegean Islands. Agios Efstratios, Thasos, Ikaria, Lesbos, Limnos, Inouses, Samos, Samothrace, Chios, Psara.
Phylum: Arthropoda. The animals in this phylum all lack back bones and are known as invertebrates. They also all have external skeletons (exoskeleton), jointed appendages and segmented body. The name of this phylum literally means jointed (from Greek arthron) foot (from Greek podos).Arthropods are the largest group of animals in the world and members of this group can be found in every type of environment. Arthropods range in size, from less than a centimeter to over 3 meters.Some of the most commonly known arthropods include ants, butterflies, spiders, shrimp, and lobsters.Subphylum: Crustacea. Animals in this group all have two-parted limbs, two pairs of antennae at some point in their life, and three body parts (head, thorax, and abdomen).he name of this phylum literally means jointed (from Greek arthron) foot (from Greek podos). Arthropods are the largest group of animals in the world and members of this group can be found in every type of environment. Arthropods range in size, from less than a centimeter to over 3 meters.
In biology, a phylum (/ËfaÉªlÉm/ ; plural: phyla) is a taxonomic rank below kingdom and above class. Traditionally, in botany the term division was used instead of phylum, although from 1993 the International Code of Nomenclature for algae, fungi, and plants accepted the designation phylum.The kingdom Animalia contains approximately 35 phyla, Plantae contains 12, and Fungi contains 7.or example, the bearded worms were described as a new phylum (the Pogonophora) in the middle of the 20th century, but molecular work almost half a century later found them to be a group of annelids, so the phyla were merged (the bearded worms are now an annelid family).
