Table 1 Morphometric and meristic characteristics of two specimens of Leucoraja circularis (female and male) from the coast of Syria, and compared with similar data previously recorded in specimen caught off the central Tyrrhenian Sea. Measurements are given as (mm) and as percentage value of TL (%)
