Plain-English definitions of the terms snake keepers actually encounter — anatomy, behavior, feeding, health, husbandry, shedding, taxonomy. More terms are added regularly.

Brumation
Brumation is a period of winter dormancy in snakes, marked by reduced activity, appetite, and metabolism in response to cooler temperatures and shorter days.
Dysecdysis
Dysecdysis is an incomplete or abnormal shedding cycle in a snake, where parts of the old skin — most often around the eyes or tail — fail to come off in one piece.
Ecdysis
Ecdysis is the normal process by which a snake sheds its outer layer of skin in one complete piece, allowing for growth and the renewal of worn or damaged scales.
Gravid
Gravid describes a female snake that is carrying developing eggs or embryos, the reptile equivalent of being pregnant.
