Wild Dolphin Population and Movements
Colossal false killer whales, dark grey and a Little smaller then Orcas, visit us in winter and usually stays until spring. Although we have seen it in August.
Considered as one of the top predators, it is very important to know its population status, in order to learn if its presence could be considered as indicative of the health of the ecosystem.
It forms groups of up to 50 individuals, its whistles are heard out of the water, they eat tuna and bonito, and mix with other dolphins. We have seen them with their little calves. We are compiling a photographic catalog of their fins, obtaining underwater sound recordings to identify possible “voice signatures” to complement individual identification. We also intend to perform a genetic analysis.
Dolphins: spinners, mixed populations, hybridation possibilities.
