Arthropods

An arthropod is an invertebrate animal having an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Euarthropoda, which includes insects, arachnids, myriapods, Eurypterids and crustaceans. Insects are a member of the largest class of the phylum Arthropoda, which is itself the largest of the animal phyla. Insects have segmented bodies, jointed legs, and external skeletons (exoskeletons). Insects are distinguished from other arthropods by their body, which is divided into three major regions: the head, which bears the mouthparts, eyes, and a pair of antennae, the three-segmented thorax, which usually has three pairs of legs (hence “Hexapoda”) in adults and usually one or two pairs of wings, and the many-segmented abdomen, which contains the digestive, excretory, and reproductive organs. Arachnids is a member of the arthropod group that includes spiders, daddy longlegs and scorpions. Only a few species are of economic importance. Spiders are adapted to make webs and possesses venomous fangs. They live in forests, caves, swamps, lakes, mountains, rainforests, forests, and Abyssal Vale. Eurypterids, Also called for Sea Scorpions, are a group of arthropods that are adapted to live under the water. Like all other arthropods, eurypterids possessed segmented bodies and jointed appendages (limbs) covered in a cuticle composed of proteins and chitin. As in other chelicerates, the body was divided into two tagmata (sections); the frontal prosoma (head) and posterior opisthosoma (abdomen). The prosoma was covered by a carapace (sometimes called the "prosomal shield") on which both compound eyes and the ocelli (simple eye-like sensory organs) were located. They feed on fish, crustaceans and shellfish also they feed on carcasses as scavengers. They possess sharp claws and claw-like stinger on their tails. Crustaceans are hard-shelled invertebrates which includes lobsters, crabs, shrimps, prawns, krills, barnacles, brine shrimps, isopods and crayfish. They can be found in shores, coasts, mangroves, swamps, coralia reefis, abyssal vale, ocean and beaches. Many people eat crabs, lobsters, crayfish, shrimps and prawns for food because they are edible. Myriapods are group of arthropods includes Centipedes and Millipedes. Myriapods' bodies are divided into two tagmata, or body sections—a head and a trunk. The trunk is further divided into multiple segments, each having a pair of appendages, or legs. Myriapods have a pair of antennae on their head and a pair of mandibles and two pairs of maxillae (millipedes only have one pair of maxillae). Centipedes have a round, flat head with one pair of antennae, a pair of maxillae, and a pair of large mandibles. Centipedes have limited vision; some species have no eyes at all. Those that have eyes can perceive differences in light and dark but lack true vision. They possess venomous fangs on their heads and immobilize prey with it. Millipedes have a rounded head that, unlike centipedes, is flat only on the bottom. Millipedes have a pair of large mandibles, a pair of antennae, and (like centipedes) limited vision. The body of millipedes is cylindrical. Millipedes are detritivores, feeding on detritus such as decomposing vegetation, organic material, and feces, and are prey for a variety of animals including amphibians, reptiles, mammals, birds, invertebrates, Dinosaurs, and Wyverns. Millipedes lack the venomous fangs of centipedes, so they must curl into a tight coil to protect themselves. Millipedes generally have 25 to 100 segments. Each thoracic segment has a pair of legs, while the abdominal segments bear two pairs of legs each.
