						Length:  0.13 - 0.31 cm; cyst 0.3 cm.  Minuscule to tiny; oval fluke has a relatively small, simple rhynchus.  Ear-like anterior projections of the body occur on either side of the rhynchus.  The eggs do not occur in the anterior part of the body.  Positions of the testes and ovary:   vary considerably (Ref. 359).					
				
				
						
			
			
			
			
				
					Host Specificity:  This fluke may be a characteristic parasite of Atlantic bonito, but reports and records are too incomplete to be certain.  It also occurs in a variety of other fishes, including many big game fishes.  Damage to Host:  The many hundreds of encysted flukes, that have been reported in each liver of some Atlantic bonito, could injure this host.  The very heavy infections of gut flukes, that have frequently been reported from this host, must also be injurious.  Habitat (vertebrates):  king mackerel; Spanish mackerel; Atlantic bonito; Atlantic mackerel; king mackerel; crevalle jack (Ref. 359).				
			
			
			
			
			
				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the class Trematoda are parasitic, thus requires a host to survive. Life cycle:  Eggs are passed on to the feces of the hosts.  Embryos hatch into miracidia and penetrate the tissues of snails where they further undergo three stages: sporocysts
