Carib Tails Whale Data Collection Program

posted in: Marine | 0

International scientists are encouraging mariners to help track the movements of endangered humpback whales between NOAA’s Stellwagen Bank National Marine Sanctuary and its sister sanctuaries across the Caribbean as part of Carib Tails, a new international citizen science effort.

Carib Tails is a collaboration between the sanctuary and partners at Marine Mammal Sanctuary of the Dominican Republic, Agoa Marine Mammal Sanctuary/French Antilles, Bermuda Marine Mammal Sanctuary, the marine mammal sanctuaries of the Windward and Leeward Dutch Antilles, and the United Nations Caribbean Environment Programme’s Specially Protected Areas and Wildlife Programme (UNEP/SPAW).

By photographing the tails of humpbacks they encounter at sea, boaters can support on-going research to collect migration data on the shared population of approximately 1,000 humpbacks. Photographs will be matched to entries in the North Atlantic Humpback Whale Catalog and images of previously unknown/un-photographed whales will be added to the collection.

The project stresses safe boating and viewing practices around these endangered animals, which includes not approaching within 100 yards of the whales, and federal regulations apply. A dedicated website,, provides tips on how to photograph flukes for research purposes, photo submission forms and other information about humpback whales.

Researchers identify individual humpback whales by the black and white patterns on the underside of their flukes, or tails. Scars and natural pigmentation, ranging from all white to all black, along with the scalloped shaped edge of the tail, give each whale a distinct identification. Photographs of humpback flukes have allowed researchers to monitor the movements, health and behavior of individual animals since this research began in the 1970s.

Stellwagen Bank sanctuary’s Sister Sanctuary Program began in 2007 to increase public awareness and help improve recovery of the shared population of humpback whales through joint research, monitoring, education and other programs.
