Are Serpents and Snakes the Same Animal?

The terms “serpent” and “snake” are often used interchangeably, yet they carry distinct connotations and origins. Understanding these nuances clarifies their relationship and why both terms persist. This article explores the linguistic, biological, and cultural distinctions between “serpent” and “snake.”

The Words and Their Meanings

In modern language, “snake” is the prevalent and scientifically accepted term for the limbless reptile. It originates from the Old English “snaca,” stemming from a Proto-Indo-European root meaning “to crawl” or “to creep,” reflecting the animal’s characteristic movement.

Conversely, “serpent” is an older term, often with a more formal, poetic, or archaic feel. Its roots trace to the Latin “serpens,” also meaning “creeping thing” or “snake,” derived from “serpere” (“to creep”). While both describe the same animal, “serpent” appears in historical texts, literature, and symbolic contexts, whereas “snake” is the standard biological descriptor.

Scientific Classification of Snakes

Biologically, all animals commonly referred to as snakes belong to the suborder Serpentes. This places them within the order Squamata, which includes lizards, and into the class Reptilia, phylum Chordata, and kingdom Animalia. The scientific community employs “snake” to denote members of this suborder, underscoring its precision.

Snakes are elongated, limbless reptiles, covered in overlapping keratin scales. Lacking external ears and movable eyelids, their eyes are protected by transparent scales, giving them a fixed gaze. They are ectothermic, relying on external heat sources to regulate body temperature, and are carnivorous predators. Their flexible skulls and jaws allow them to swallow prey much larger than their heads.

The Serpent in Culture and Myth

The term “serpent” often evokes mystery and ancient symbolism, explaining its continued presence in non-scientific discussions. Across diverse cultures, the serpent holds a prominent place in mythology, religion, and folklore. It frequently symbolizes duality, encompassing themes such as wisdom, healing, rebirth, and immortality, but also evil, chaos, and temptation.

In various traditions, the serpent represents creation or cosmic cycles, as seen with the Ouroboros, an ancient symbol of a snake eating its own tail, signifying eternal return and unity. The biblical narrative of the Garden of Eden portrays a serpent as a tempter, linking it to deception and sin. In Norse mythology, the Midgard Serpent, Jörmungandr, encircles the world, embodying a powerful cosmic entity. These cultural associations lend “serpent” a deeper, often mystical, significance.
