More generally, a multimodal distribution is a continuous probability distribution with two or more modes, as illustrated in Figure 3.

Killer whales are among the fastest swimming marine mammals. Killer whales can swim at speeds of up to 45 kph (28 mph), but probably only for a few seconds at a time. Killer whales usually cruise at much slower speeds, less than 13 kph (8 mph). They can cruise slowly for long periods of time. Killer whales are agile and maneuverable in the water.
