Sand eel
common name used for a considerable number of species of fish

Sand eel or sandeel is the common name used for a considerable number of species of fish. While they are not true eels, they are eel-like in their appearance and can grow up to 30 cm (12 in) in length. Many species are found off the western coasts of Europe from Spain to Scotland, and in the Mediterranean and Baltic Seas.
Sand eels are an important food source for seabirds, including puffins and kittiwakes. They are a commercially important for the production of fish meal and made up 4% of fish globally caught for fish-meal production (behind anchovy, capelin, and blue whiting) between 1997 and 2001.
Habitat
The preferential habitat for sand eels is a seabed floor, with a relatively smooth bottom of gravelly sand; an example of this prime habitat is the floor of the Sea of the Hebrides.
Sand eel species
Most sand eels are sea fish of the genera Hyperoplus (greater sand eels), Gymnammodytes or Ammodytes. The three genera listed above all fall within the family Ammodytidae, the sand lances. Members of these genera found in other oceans are not usually called sand eels, and species from other parts of the world that are known as sand eels are usually less closely related.
Commercial fishing
Traditionally, they have been little exploited for human food, but are a major target of industrial fishing for animal feed and fertilizer.

Why this record matters
The phrase “common name used for a considerable number of species of fish” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 27, 2026. The linked authority identifier is Q15817131. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1997 and 2001.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
