stenotele
A specialized term in cnidarian biology referring to a type of penetrating nematocyst (stinging cell) with a narrow shaft, used for prey capture and defense.
Many stenoteles are distributed on the tentacles of Hydra.
The term is composed of 狭 (narrow), 端 (end/tip), and 体 (body), reflecting the narrow shaft structure of this nematocyst type. The reading is on'yomi, likely coined in scientific contexts.
