These amazing animals can be seen in Madeira’s waters all year round. They use our warm and calm sea to dive and eat, socialize, and procreate. Their dive can last 1 hour and 30 minutes! Adult subjects they can be 17 to 20 meters long ! Usually, we use their water projection to identify them, as they need to blow in order to breathe. They present a rough grey-brown body, and a big smooth head. They tail-fin is triangular shaped and we can usually see it poping out of the water as they are diving back.
