Crustaceans are generally aquatic and differ from other arthropods in having two pairs of appendages (antennules and antennae) in front of the mouth and paired appendages near the mouth that function as jaws.

What characteristics distinguish crustaceans from other arthropods?
Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their larval forms, such as the nauplius stage of branchiopods and copepods.
What is the easiest way to distinguish between an insect and a crustacean?
What is the easiest way to distinguish between an insect and a crustacean? Crustaceans have two pairs of antennae, and insects have only one pair. There are two major groups of bilaterally symmetrical, triploblastic animals: protostomes and deuterostomes.
What characteristics of insects distinguish them from all other arthropods?
Insects are distinguished from other arthropods by their body, which is divided into three major regions: (1) the head, which bears the mouthparts, eyes, and a pair of antennae, (2) the three-segmented thorax, which usually has three pairs of legs (hence “Hexapoda”) in adults and usually one or two pairs of wings, and ...
Which feature is characteristic only of crustaceans?
A crustacean has the following features: a segmented body with a hard exterior (known as an exoskeleton) jointed limbs, each often with two branches (termed biramous) two pairs of antennae.
What is the difference between crustaceans and arachnids?
Unlike crustaceans, arachnids have no antennae and mandibles. Most arachnids are terrestrial, and few are secondarily aquatic, whereas crustaceans are exclusively aquatic. Examples for arachnids include scorpions, spiders, mites, and ticks. Examples of crustaceans are prawns, lobsters, shrimps, barnacles, and crabs.
What's the difference between arthropods and crustaceans?
Arthropods are animals with exoskeletons (external skeletons), segmented bodies, and jointed legs. Crustaceans include lobsters, crabs, crayfish, and shrimp. ... They are mostly aquatic animals, and some, like lobsters and crabs, are relatively large animals.
What distinguishes an insect from crustacean?
Insects have a chitinous exoskeleton and have a three-part body. They are the most diverse group on earth. Complete answer:Crustacean is chiefly aquatic arthropod of the class crustacea. ... The distinguishing feature between an insect and crustacean is the number of appendages'.
Do crustaceans have antennae?
Crustaceans have two sets of antennae: short antennules (first antennae) and antennae posterior or lateral to them (second antennae) which are often much longer.
What physical characteristics do insects arachnids and crustaceans have in common?
Along with arachnids, crustaceans and insects belong to the same group—arthropods. Sharing distinctive physical characteristics, such as absence of backbone, hard exoskeletons, jointed legs and segmented bodies, arthropods are easily distinguished from other animal groups.
How are arachnids different from other arthropods?
Like other arthropods, arachnids have paired, jointed appendages, a hardened exoskeleton, segmented body, and well developed head. Unlike other arthropods, their body has two main parts, the prosoma (equivalent to an insect's head and thorax) and the opisthosoma (or abdomen).
What characteristics make crustaceans different from other arthropods quizlet?
The characteristics that distinguish crustaceans from other arthropods are that they have gills, two body systems, and two pairs of antennae. List the nine life processes of animals and briefly tell how a crayfish accomplishes each of these processes.
How do the appendages of crustaceans differ from other arthropod groups?
How do Crustacea differ from other arthropod groups? A) They possess a telson tail. B) Only crustaceans have two pairs of antennae.
Which feature is characteristic only of crustaceans quizlet?
Most species have two regions; cephalothorax and abdomen, pair of mandibles, pair of appendages on each body segment, some branched appendages, 16 to 20 segments and several tagmata. The one characteristic that is unique in crustacea is that they have two pairs of antennae.
