The karyotype of a sandlance species, Gymnammodytes cicerelus , comprises: seven meta‐centric, seven submetacentric and nine subtelocentric‐acrocentric pairs (2 n =46, FN=74). The C‐bands appear in paracentromeric and telomeric areas of most chromosomes and the NOR regions, in two pairs of larger chromosomes. All these characteristics indicate that a large number of rearrangements seem to have been involved in the karyotype evolution of this species.
