The family name for water scorpions is Nepidae. Water scorpions are aquatic true bugs commonly found in freshwater habitats. This family is characterized by their elongated bodies and long, slender respiratory siphon, which resembles the tail of a scorpion, hence the name "water scorpion." These adaptations allow them to be effective predators in their aquatic environments. They primarily feed on small aquatic invertebrates and sometimes even small fish, utilizing their raptorial front legs to capture prey.

The other families listed do not refer to water scorpions. Notonectidae is the family of backswimmers, notable for their swimming ability but distinct in morphology from Nepidae. Corydalidae and Sialidae pertain to different groups of insects entirely—Corydalidae includes dobsonflies, and Sialidae refers to the family of snakeflies. Understanding these distinctions is crucial for accurate identification and classification in freshwater ecosystems.
