[A Master of Science thesis for the University of East Africa. The family Istiophoridae contains about 10 species, of which the best known is the marlin.. It has an elongated body, a spear-like snout or bill, and a long, rigid dorsal fin which extends forward to form a crest. Its common name is thought to derive from its resemblance to a sailor's marlinspike. Even more so than their close relatives, the scombrids, marlins are fast swimmers, reaching speeds of about 80 km/h (50 mph)].. First Edition. Cloth. Good.
