The 411 - Crustaceans - Are they just bugs of the ocean?

Crustaceans are not considered bugs in the scientific sense, as the term "bug" typically refers to insects belonging to the order Hemiptera. Crustaceans belong to a different group of arthropods that includes lobsters, crabs, shrimp, and barnacles, among others. While both crustaceans and insects are classified as arthropods, they have distinct differences in their body structures, life cycles, and other characteristics.

Lobsters are not part of the insect family or closely related to insects. Lobsters belong to a different group of arthropods known as crustaceans. While both crustaceans and insects belong to the larger group of animals known as arthropods and share some similarities in their body structures, they have distinct differences in their anatomy, physiology, and behaviour. Insects have three pairs of legs, three body segments, and wings, while crustaceans have five or more pairs of legs, two or three body segments, and typically lack wings.

Crustaceans are related to insects in the sense that both groups of animals belong to the larger phylum Arthropoda, which also includes spiders, centipedes, and millipedes. However, crustaceans are not considered "bugs of the ocean," as the term "bug" specifically refers to insects belonging to the order Hemiptera. Crustaceans are a diverse group of marine and freshwater animals that include lobsters, crabs, shrimp, and barnacles, among others. While they share some similarities with insects, such as having jointed limbs and segmented bodies, crustaceans have distinct differences in their anatomy, physiology, and behaviour. 

Since I have started to think of Lobsters as bugs, I have completely stopped eating them - turns my stomach. Even after researching this post, I still am totally turned off by crustaceans...
