The Hawaiian stingray, Dasyatis lata, is a common benthic elasmobranch in nearshore Hawaiian waters. Acoustic telemetry was used to track the movements of seven rays in Kaneohe Bay, Oahu, Hawaii. Rays were tracked continuously over 31–74 h periods. Geographical movements were analyzed to determine space utilization and rate of movement. Rays were found to utilize significantly larger activity spaces at night (0.83±0.70 km2) (mean±SD) than during the day (0.12±0.15 km2). Mean total activity space for rays tracked was 1.32±0.75 km2. Rates of movement were also significantly higher at night (0.34±0.30 km h-1) than during the day (0.15±0.22 km h-1). Average straight-line swimming speed was 0.64±0.16 km h-1, with a maximum observed swimming speed of 1.9 km h-1. Tidal stage had no effect on rate of movement. Comparison with previously published data on juvenile scalloped hammerhead sharks, Sphyrna lewini, in Kaneohe Bay revealed a high degree of overlap in habitat use and time of activity, suggesting possible ecological interactions between these two species.

Distribution and diet of four species of carcharhinid shark in the Hawaiian Islands: evidence for resource partitioning and competitive exclusion (2006, background): “The few studies that have attempted to investigate competition and resource partitioning between elasmobranchs have examined dietary and habitat overlap among sympatric species within small spatial scales (e.g. Cartamil et al. 2003, Bethea et al. 2004, White et al. 2004).”
migratory behaviour of the thornback ray, raja clavata, in the southern north sea (2005, methodology): “In addition, a maximum swimming speed of one body length per second was assumed as part of the process used to identify a plausible sequence of geolocations (Cartamil et al., 2003).”
