Arthropoda 1 Diagram Quizlet Arthropoda [1] the phylum arthropoda is the largest and most varied in the animal kingdom. it includes well over one million described species. this represents approximately three quarters of all known biological organisms, living or extinct. Centipedes centipedes (phylum arthropoda, class chilopoda) occur throughout the world in both temperate and tropical regions, living in soil and humus and beneath fallen logs, bark, and stones. because they lack a hard outer skeleton, centipedes are confined to moist environments in order to maintain their water balance. many species are therefore active only at night, remaining sheltered.
Arthropoda Diagram Quizlet Arachnids arachnids (class arachnida) form the second largest group of terrestrial arthropods (phylum arthropoda) with the class insecta being the most numerous. there are over 70,000 species of arachnids, which include such familiar creatures as scorpions, spiders, harvestmen or daddy longlegs, and ticks and mites , as well as the less common whip scorpions, pseudoscorpions, and sun spiders. Merostomata (horseshoe crabs) phylum arthropoda class chelicerata subclass merostomata number of families 1 thumbnail description marine creatures distinguished by a large, hard exoskeleton that includes an arched, horseshoe shaped shield in front (prosoma), a middle portion (opisthosoma), and a thin tail (telson); they are among the oldest living organisms. Trilobita (trilobites; phylum arthropoda) the most primitive arthropod class (or in some classifications a phylum, where the arthropoda rank as a superphylum), known from more than 3900 fossil species. inhabitants of palaeozoic seas, the trilobites appeared first in the early cambrian, had their widest distribution and greatest diversity in the cambrian and ordovician periods, and became.

Uniramia formerly a phylum or a subphylum of arthropoda, in which the appendages are unbranched (i.e. uniramous) and at one time classed as members of the mandibulata. the group includes the myriapods (centipedes and millipedes) and the insects, the earliest known fossils being devonian and resembling modern centipedes and millipedes. the arthropoda are now held to have evolved only once (they. Arthropods: insects, arachnids, and crustaceans arthropods: insects, arachnids, and crustaceans. arthropods are animals with exoskeletons (external skeletons), segmented bodies, and jointed legs. they are the largest group of animals on earth and include insects, crustaceans, and arachnids. insects include organisms such as beetles, grasshoppers, and butterflies. they are mostly terrestrial. Crustacean the crustacea are a subphylum of the animal phylum arthropoda. this is a large and diverse group with more than forty thousand species, including crabs, shrimp, lobsters, crayfish, barnacles, and many near microscopic members of the zooplankton community. Barnacles the rocky shores of most coastlines are liberally dotted with clusters of barnacles (phylum arthropoda, class crustacea). barnacles are exclusively marine animals: approximately 1,000 species have been identified worldwide. many are tiny organisms measuring just a few centimeters in diameter, while others such as the south american balanus psittacus may reach a height of 9 in (23 cm.
