water moccasin
C1Technical (Biology/Zoology), Regional, Informal (in metaphorical use)
Definition
Meaning
A large, venomous semi-aquatic pit viper (Agkistrodon piscivorus) native to the southeastern United States.
A term for a dangerous, stealthy threat in a watery or marshy environment. Can be used metaphorically for a hidden danger.
Linguistics
Semantic Notes
The term is a compound noun. The 'moccasin' part refers to the snake's family (pit vipers), not the footwear. It's a specific species, not a general term for any water snake.
Dialectal Variation
British vs American Usage
Differences
The term is almost exclusively used in American English due to the snake's geographical range. In British English, the concept is foreign and the term is only used in specific zoological or travel contexts.
Connotations
In American English, it connotes regional danger, swamps, and the American South. In British English, it has little cultural connotation beyond being an exotic, dangerous animal.
Frequency
Very high frequency in relevant American regions (Southeast); very low to zero in British English outside specialized texts.

FAQ
Frequently Asked Questions
Yes, 'water moccasin' and 'cottonmouth' are common names for the same species, Agkistrodon piscivorus.
Its bite is venomous and requires immediate medical attention, but fatalities are rare with modern antivenom treatment.
Their native range is primarily the southeastern US, extending into parts of the Midwest and Mid-Atlantic. They are not found in the wild in Europe or the UK.
Key differences include the head shape (triangular vs. more rounded), body thickness, and the presence of a heat-sensing pit between the eye and nostril. The most famous sign is the cottonmouth's defensive display of its white mouth.
