Proportion of females caught during (A) the day and (B) the night and proportion of immature 
individuals caught during (C) the day and (D) the night for 11 elasmobranch species sampled 
along the Pacific coast of Costa Rica during 2010-2012. The following species abbreviations are 
used: MHE (brown smoothhound [Mustelus henlei]), MLU (sicklefin smoothhound [Mustelus lu- 
nulatus ]), UAS (Panamic stingray [Urotrygon aspidura]), UCH (blotched stingray [Urotrygon 
chilensis]), URO (thorny stingray [ Urotrygon rogersi]), RVE (rasptail skate [Raja velezi]), ZXY 
(witch guitarfish [Zapteryx xyster]), DOM (bullseye electric ray [Diplobatis ommata]), NEN (gi- 
ant electric ray [Narcine entemedor ]), NVE (vermiculate electric ray [Narcine vermiculatus]), and 
TPE (Peruvian torpedo [Torpedo peruviana]).
