EPIPHRAGM Meaning and
Definition
-
An epiphragm is a protective membrane or structure that certain organisms, particularly snails and slugs, create to cover their soft bodies. The term comes from the Greek words "epi," meaning "upon," and "phragma," meaning "fence" or "partition." This unique adaptation serves multiple purposes, providing insulation, moisture retention, and defense against predators.
The epiphragm is typically composed of a mixture of mucus and calcium carbonate secreted by the organism. It is often formed at the entrance of the snail or slug's shell, sealing it shut. This membrane effectively creates a barrier between the internal organs of the organism and the external environment, preventing desiccation and protecting against potential threats. In times of drought or extreme temperatures, the epiphragm plays a crucial role in reducing water loss and maintaining the organism's internal moisture levels.
When threatened or entering periods of inactivity, snails or slugs will retract into their shells and seal the opening with the epiphragm. This serves as a defensive mechanism by preventing access to their vulnerable body parts. The epiphragm can be dissolved or reabsorbed when conditions improve or when the organism becomes active again.
Overall, the epiphragm is a remarkable adaptation found in certain gastropods that helps them to survive in challenging environmental conditions and protect themselves from potential harm.

Etymology of EPIPHRAGM
The word "epiphragm" is derived from the Greek word "epíphragma" (ἐπίφραγμα), which is a compound of "epí" (ἐπί), meaning "upon" or "in addition to", and "phragma" (φραγμα), meaning "a fence" or "a barrier". The combination of these two elements gives "epiphragm" its meaning, which is a anatomical or biological structure that acts as a seal or barrier.
