Echinometra lucunter  is a common Caribbean sea urchin, which the abundance and distribution were evaluated along a rocky platform at Cepe beach, Venezuela. Two surveys were conducted along transects perpendicular and parallel to the coast, from the shore to the wave breaking zone (WB), using 1m 2  quadrat method. In survey-1 the smaller sea urchins (&lt;1.8 cm) occurred in the tide pool zone (TP) and medium and large dominated in the WB. The average density recorded in the WB and TP (140.2 and 272.7 ind/m 2  respectively) are among the highest values reported in the Caribbean. The maximum density recorded was 562 ind/m 2  in the TP and most of them were juveniles (&lt;1.8 cm). In survey-2 sea urchins (³3.0 cm) density ranged from 1 to 156 ind/m 2  and the overall average was 29.6 (± 32.4) ind/m 2 . The highest density occurred in the platform western sector (average 43.2 ±41.3 ind/m 2 ). In the transects parallel to the coast the sea urchin's abundance gradually decreased from the WB (130 ±12 ind/m 2 ) towards the coast (0.3 ±0.37 ind/m 2 ). In conclusion, the  E. lucunter  densities recorded on the Cepe beach platform are the highest values reported in the Caribbean.
