Abundance has only been estimated for the northern Gulf of Mexico and US east coast (6,575 (CV=36%) and 6,086 (CV=93%), respectively -- Waring et al. 2008). However, considering the difficulty of distinguishing it from similarly marked species at sea, it may not be as rare as it would seem to be (Perrin and Mead 1994). Based on capture records, S. clymene appears to be the most common cetacean in Ghana's coastal waters (Van Waerebeek et al. 2000).
