Madeira: Occur all year around; often in small harem groups with several females in the company of one bull.
Distinctive features: Robust body, containing a characteristic yellowish tint due to a parasite. Their small and flat forehead (melon) extends into a long beak with distinctive arched mouthline. They have a relatively small, triangular dorsal fin, set far back towards the fluke.

They surface with their beaks pointing up and emit a small spout.
Taxonomy: Suborder: Odontoceti (Toothed Whales); Family: Ziphiidae (Beaked Whales)
Threats: Noise pollution leads to an increase in mass strandings of these acoustically sensitive creatures. The most recent report on standings due to acoustic trauma was in September 2002 when 14 dead whales were washed ashore in Fuerteventura shortly after naval military excercises were conducted in the area. Are also popular victims of plastic pollution and bycatch. Their global population size is unknown.
