| Summary: | (COAS) were calculated for all individuals identified more (Gulf). Group sizes ranged from I to 29 with a median of 10.5 and mean of I 1.0 ( ︢SD 8.37). A significant difference 1995-96 were present in 1990, suggesting that some dolphins 3.74). A seasonal calving peak occurred between late March a 12-month (1995-96) study of bottlenose dolphins, Tursiops affiliates for Bay animals ranged from I 46, with an overall and mid-July. Distribution shifted from Chocolate Bay in the animals were resighted in Galveston Bay, an indication of area in 1990. Fourteen of 71 (19.7%) animals identified in assess the potential impact of humans and industry on this Boat-based photo-identification surveys were conducted during coastal movements between study sites. Results were compared compared to photographs taken during weekly surveys of exhibit longterm site fidelity to this area. To investigate Galveston Bay (approximately 48 km away) in 1995. Three Groups containing calves (mean = 14.9 ︢SD 7.29) were identified, including 37 residents (Bay) and 34 transients in group size by season was documented, with largest and indices between residents (median = 0.455). COAs for known located at the northeastern end of Galveston Island, to male pairs were among the highest recorded. During all mean of 33.27 ( ︢SD 9.904). Coefficients of association movement patterns, dolphins identified in San Luis Pass were observed behavior. Individuals identified during this study of Galveston Island. Seventy-one individuals were relatively undisturbed area located at the southwestern end seasons except spring, feeding was the most frequently significantly larger than non-calf groups (mean = 3.3 ︢SD smallest groups present during spring and fall, respectively. species' distribution and behavior. summer to the Gulf of Mexico during winter.
