Question

Shrimps, Crayfish, and Lobsters belong to the class
(a) Insecta
(b) Crustacea
(c) Arachnida
(D) Chilopoda

Answer 1

Hint: They are the group of the phylum Arthropoda but having differences in their limbs and larva structure. They are generally found near the coast and have hard exoskeleton. They have four pairs of jointed legs.

Complete answer:
An arthropod is an invertebrate animal with an exoskeleton, a segmented body, and jointed appendages that are paired.
Arthropods are found in the mountain peaks to the seashore. All the arthropods have jointed legs and have similar body types. Therefore, Shrimps, Crayfish, and Lobsters belong to the class Crustacea.
Shrimps: They are crustaceans having organs for locomotion. They are the small crustaceans with jointed legs that can be eaten and are a good source of high-quality protein, vitamins, and minerals which help in making a healthy diet. They constitute low calories and are made up of healthy cholesterol.
Crayfish: They are freshwater crustaceans and are similar to lobsters. They respire through gills and are generally found near the United states.
Lobsters: They are large marine crustaceans having muscular tales and live in the burrows on the seafloor. They are mostly found in the coastal area having no claw and are economically important. They are consumed as food in the form of boiled or steamed meat.

So, the correct answer is ‘Crustacea’.

Note:
Insects comprise three pairs of jointed legs and a three-part body including head, thorax, and abdomen. Some insects may be parasites that are also considered as pests. Arachnida are the joint-legged arthropods that are terrestrial in nature and are invertebrates. Chilopoda consists of the leg and the segment which is a result of two single segments fused. They are Predatory in nature.
