Crabs, lobsters, shrimp, barnacles and many other animals belong to the phylum arthropods. Among them, crabs, shrimps, and prawns are some of the most attracted species and giving attention in relation to their use as health foods and various types of MNPs They are a very diverse group of animals that includes but is far from limited to insects, crustaceans, spiders, scorpions, and centipedes. Radial symmetry is the arrangement of similar features around a center. It is the largest phylum with more than 80% of living animals falling into this category.This phylum includes insects, crustaceans, arachnids etc.The characteristics of the Phylum Arthropoda are:1) Exoskeleton - All members of this phylum have an external skeleton made of chitin. Another class of arthropods is the crustaceans, including crabs, shrimp, lobster, and crayfish. Class The P. xuthus is found in the class Insecta. There are far more species of arthropods than species in all other phyla combined, and the number of undescribed species in the largest assemblage of arthropods, the insects, probably numbers in the tens of millions. CRUSTACEA CHELICERATA MYRIAPODA HEXAPODA The Phylum Arthropoda is the largest phylum of animals, containing over one million known species! Arthropods are an incredibly diverse, successful group of invertebrate animals that includes insects, crustaceans, and arachnids (and a few other less well known groups). Five major classes divide the phylum Arthropoda. Types of Arthropods. Phylum Arthropoda includes animals that have been successful in colonizing terrestrial, aquatic, and aerial habitats. They are mostly marine animals. e. have no true tissues. Arthropoda are also known as the most taxonomically diverse phylum on the planet. Arthropods.
