False Killer Whale * Valsmoordvis * Pseudorca Crassidens

Dolphin Dolfyn
It is widespread throughout the world's oceans, but is primarily found in tropical oceans. It can form pods with other dolphin species, such as the common bottlenose dolphin, and is known to form groups of up to 50 individuals.

Males grow to a maximum size of 6 m (20 ft) long and 2,000 kg (4,400 lb), while females grow to a maximum size of 5 m (16.4 ft) long and 1,200 kg (2,600 lb).

During the day, the false killer whale typically hunts a vast variety of squid and fish of all sizes.  They frequently go after larger fish species like tuna. 

The false killer whale has been kept in various public aquariums around the world because it is believed to be considerably more adaptive in captivity than other dolphins, being quickly trained and highly friendly with other species.
The false killer whale frequently beaches itself on coastlines around the world, for reasons that are mostly unknown. The largest stranding, which included 835 animals, occurred at Mar del Plata in Argentina on October 9, 1946, as indicated by the below image.
