Orthione griffenis is an Epicaridean isopoda parasite that is found on the gill chamber of Upogebia mud shrimp. [3] Female O. griffenis are quite different from their male counterpart. Females have an oblong body, that is typically 6-24mm long with a width of half the length.
Parasites can provide information about host population ecology. In fisheries biology, for example, parasite communities can be used to distinguish distinct populations of the same fish species co-inhabiting a region. [9] Additionally, parasites possess a variety of specialized traits and life-history strategies that enable them to colonize hosts.
Lysmata amboinensis is an omnivorous shrimp species known by several common names including the Pacific cleaner shrimp.It is considered a cleaner shrimp as eating parasites and dead tissue from fish makes up a large part of its diet.
The term "cleaner shrimp" is sometimes used more specifically for the family Hippolytidae and the genus Lysmata. Cleaner shrimp are so called because they exhibit a cleaning symbiosis with client fish where the shrimp clean parasites from the fish. The fish benefit by having parasites removed from them, and the shrimp gain the nutritional value ...
Then there’s a parasitoid worm that Smith photographed curled inside a shrimp, like spaghetti: “It starts off infecting the shrimp and then it grows, eating the least important organs to start ...
The shrimp Palaemon serratus of the infraorder Caridea. A shrimp (pl.: shrimp or shrimps ()) is a crustacean (a form of shellfish) with an elongated body and a primarily swimming mode of locomotion – typically belonging to the Caridea or Dendrobranchiata of the order Decapoda, although some crustaceans outside of this order are also referred to as "shrimp".
S. hippolytes castrates infected female shrimp by absorbing the reproductive energy of the host. Many other Rhizocephalan have the same castrating characteristic. The presence of the parasite will eventually come to pass after it dies, and the castrating mechanism is reversed for the host.
The most common is the second intermediate hosts, grass shrimp, Palaemonetes pugio. Metacercariae of the parasite usually encyst in grass shrimp abdominal muscle, [5] and though adult P. pugio average only 2.9 cm in length, a shrimp can be infected with more than 100 parasites. [6]
