STINGING CAPSULE Meaning and
Definition
-
A "stinging capsule" refers to a specialized, microscopic structure found in certain organisms, primarily in nematocysts or cnidocytes of various marine organisms such as jellyfish, sea anemones, and corals. It is an essential component of their defense and prey capture mechanism.
The stinging capsule, also known as a cnidocyst, is a tiny, fluid-filled, eversible cell that contains a coiled, filamentous tube called a filament, and a venom-filled cavity referred to as the nematocyst. These structures are produced by specialized cells within the organism's tentacles or body.
When triggered by contact or certain stimuli, the stinging capsule rapidly discharges its contents. This process entails the expulsion of the filament, which swiftly extends, launching venomous barbs or harpoons into the target. The venom can immobilize prey or deter potential predators, causing a painful, stinging sensation upon contact with humans.
The action of the stinging capsule is facilitated by both mechanical and chemical triggers. Physical contact, changes in temperature, salinity, or pH, and even the presence of particular molecules can activate the discharge. The speed and force of this discharge make the stinging capsule an effective defense and feeding tool.
In summary, a stinging capsule is a specialized microscopic cell found in certain marine organisms that contains venom and utilizes a filament to sting and immobilize prey or deter potential threats.

Etymology of STINGING CAPSULE
The word "stinging capsule" does not have a specific etymology because it is a combination of two separate words:
1. "Stinging": The word "sting" has Old English origins and can be traced back to the Proto-Germanic word *stinganą. It has been used to refer to the sensation caused by a sharp or pointed object piercing the skin.
2. "Capsule": This word comes from the Latin word "capsula", which means a small box or case. It eventually entered the English language and refers to a small container or envelope.
When these two words are combined, "stinging capsule" is used to describe a specific type of organism or structure that contains a stinging mechanism.
