sea cucumber
LowTechnical/Biological, Culinary
Definition
Meaning
A marine animal with a long, soft, cylindrical body, belonging to the class Holothuroidea, found on the sea floor.
A term sometimes used metaphorically to describe a person or thing that is soft, flexible, or passive. Also refers to the edible form of the animal, considered a delicacy in some Asian cuisines.
Linguistics
Semantic Notes
The term is a compound noun where 'sea' specifies the habitat and 'cucumber' refers to the vegetable-like shape. It is not a true cucumber but an echinoderm related to starfish.
