Exocoetidae is a family of marine fish in the order Beloniformes of class Actinopterygii. Fish of this family are known as flying fish. There are about sixty-four species grouped in seven to nine genera. Flying fish can make powerful, self-propelled leaps out of water into air, where their long, wing-like fins enable gliding flight for considerable distances above the water’s surface. This uncommon ability is a natural defense mechanism to evade […] read more

The tree is native to central and southern Chile and western Argentina.[1] Araucaria araucana is the hardiest species in the conifer genus Araucaria.
