The Bottlenose Dolphin Coastal and offshore 400-600 lbs, +9 ft. Long! Eat small fish and squid Strand feed Kerplunk

Biological Indicators Bottlenose dolphins are important indicators of coastal environmental health. Long life span Top predators Concentrate contaminants
5
Conservation of the Bottlenose Dolphin Protected species under the Marine Mammal Protection Act of 1972 Protected species under the Marine Mammal Protection Act of 1972 “Optimum Sustainable Population” “Optimum Sustainable Population” If not => conservation plan If not => conservation plan GA Permit (OBXCDR) GA Permit (OBXCDR)
