Definition
Noun: 1. A type of small marine fish: Refers to any of several small wrasse species characterized by having laterally compressed bodies and very narrow, sharp-edged heads. These fish are found in regions including the West Indies and the Mediterranean Sea.
Usage Notes
- The term "razor-fish" is a common name, not a precise scientific classification. It is used to describe specific fish within the wrasse family (Labridae) based on their distinctive head shape.
- The name derives from the fish's physical resemblance to the handle of a straight razor, which is thin and sharp-edged.
Examples
- Noun:
- While snorkeling in the Mediterranean, we spotted a school of colorful razor-fish darting near the seabed.
- The razor-fish uses its narrow head to probe into crevices for small crustaceans.
Advanced Usage
- The term can sometimes be used regionally to refer to other elongated marine animals, such as certain bivalve mollusks (e.g., spp.), also known as "razor clams." However, the primary zoological definition pertains to the wrasse species.
