Phylum Annelida- characteristics, classification, examples About 8,700 known species of Annelida are divided into four main classes, primarily on the basis of presence and absence of parapodia, setae, metameres, and other morphological features
Annelid - Examples, Characteristics, Anatomy, Pictures Annelids, commonly known as segmented worms, are soft-bodied, bilaterally symmetrical invertebrates of the phylum Annelida They constitute the earthworms, leeches, and ragworms, traditionally grouped into polychaetes, oligochaetes (including earthworms), and leech -like species
Phylum Annelida | Biology for Majors II - Lumen Learning Phylum Annelida includes segmented worms These animals are found in marine, terrestrial, and freshwater habitats, but a presence of water or humidity is a critical factor for their survival, especially in terrestrial habitats
Phylum Annelida – Definition, Characteristics, Classification, Examples In summary, phylum Annelida encompasses a diverse array of segmented worms found in marine, terrestrial, and freshwater habitats These animals exhibit metamerism, or true segmentation, and display a range of adaptations for locomotion and survival
Annelida (segmented worms) | INFORMATION | Animal Diversity Web Members of the Phylum Annelida can be found throughout the world, in marine, freshwater, and terrestrial environments Ecologically, they range from passive filter feeders to voracious and active predators
