The Research Team on board the Dolphin Explorer is happy to share information about your area dolphins with the Coastal Breeze News readers. Each edition an individual will be profiled so that you, too, might get to know them. Dolphins can be identified by the nicks and marks on their dorsal fins.
This big guy is an adult male, seen mostly in the area of the Jolley Bridge in Marco Island.
Rocky has quite a few nicks and notches on his dorsal fin, which is common for males. Two or more big boys can be aggressive toward each other at times, especially when competing for the attention of the females, causing these markings.
