ovary

Female reproductive organ, producing ova [Butler, T.H.].

In free-living copepod unpaired, parasitic copepod paired, expanded section of female reproductive system in which eggs are produced. Located dorsally, above midgut, near border of head and thorax. Opens to exterior on first abdominal segment (genital somite) via oviduct. (paired, unpaired) [Stachowitsch, 1992].

The organ which produces the female gametes or ova [Ingle, 1983].

(Order Cladocera):

Paired section of female reproductive system in which eggs are produced; typically extends through anterior part of trunk, one alond each side of midgut. Opens dorsally via oviduct into brood chamber [Stachowitsch, 1992].

(Order Notostraca):

Gonad [Stachowitsch, 1992].

(Order Diplostraca):

Gonad [Stachowitsch, 1992].

(Order Anostraca):

Paired section of female reproductive system in which eggs are produced; extends anteriorly from fourth or fifth abdominal somite to eighth or seventh thoracic somite. Opens to exterior via oviduct originating near first or second abdominal somite (= genital somite) [Stachowitsch, 1992].

(Class Cephalocarida):

One of two sections of female reproductive system in which eggs are produced. Located in posterior end of head (cephalon) and opens exterior via highly elongated oviduct and short common gonoduct [Stachowitsch, 1992].

(Order Cumacea):

Section of female reproductive system in which eggs are produced. Paired, tube-like, located on each side in person. Each ovary opens to exterior on third pereopods via oviduct [Stachowitsch, 1992].

(Order Tanaidacea):

Section of female reproductive system in which eggs are produced. Paired, tube-like, extending through most of pereon. Each ovary opens to exterior via oviduct [Stachowitsch, 1992].

(Order Decapoda):

Paired, expanded section of female reproductive system typically located in posterodorsal region of cephalothorax. Connected by bridge, each ovary opening to exterior on basal segment (coxa) of third pereopod via oviduct [Stachowitsch, 1992].

(Order Amphipoda):

Paired section of female reproductive system in which eggs are produced. Elongate, cylindrical, extending between heart and digestive tract in pereon. Each ovary opens to exterior on fifth pereon segment (pereonite) via oviduct and gonopore [Stachowitsch, 1992].

(Order Isopoda):

Paired section of female reproductive system in which eggs are produced. Located dorsolateral to digestive tract in pereon, each ovary opening to exterior on ventral surface (sternite) of fifth pereon segment (pereonite) via oviduct [Stachowitsch, 1992].

(Order Mysida):

Paired section of female reproductive system in which eggs are produced. Located dorsolateral to digestive tract in thorax. May be connected by bridge. Each ovary opens on base of sixth thoracopod via oviduct [Stachowitsch, 1992].

(Order Stomatopoda):

Paired section of female reproductive system in which eggs are produced. Elongate, extending along thorax and abdomen between heart and digestive glands. Fused posteriorly in telson and opening to exterior on sixth thoracic somite (thoracomere) via pair of oviducts, unpaired seminal receptacle, and gonopore [Stachowitsch, 1992].

(Order Leptostraca):

In female reproductive system, pair of relatively slender, tubular organs in which eggs are produced; located between digestive tract and heart and extending through most of body. Each ovary opens at base of sixth thoracopods via oviduct [Stachowitsch, 1992].

(Subclass Branchiura):

Large, unpaired section of female reproductive system in which eggs are produced. Occupies greater part of thorax and opens to exterior via pair of short oviducts. Described as being located within separate body cavity (gonocoel) [Stachowitsch, 1992].

(Subclass Cirripedia):

Paired section of female reproductive system located in peduncle (stalked barnacle) or anteriorly in basis and mantle wall (unstalked barnacle). Each ovary opens to exterior via oviduct [Stachowitsch, 1992].

(Subclass Mystacocarida):

Unpaired section of female reproductive system in which eggs are produced. Considered to consist of ovary proper and nutritive section ("yolk gland"). Extends throughout thoracoabdomen and opens to exterior via oviduct [Stachowitsch, 1992].

(Class Ostracoda):

Section of female reproductive system in which eggs are produced. Typically paired, located in posterior region of trunk, and opening to exterior via oviducts. (paired, unpaired) [Stachowitsch, 1992].

(Class Remipedia):

Unpaired section of female reproductive system in which eggs are produced; located dorsally in posterior region of head (cephalon) and opening to exterior on seventh trunk segment via oviducts [Stachowitsch, 1992].

(Superorder Syncarida):

Section of female reproductive system in which eggs are produced. Paired, in anaspidacean, extending from anterior or posterior half of thorax to end of abdomen. Each ovary opens to exterior via oviduct. Restricted to abdomen in bathynellacean [Stachowitsch, 1992].

(Order Thermosbaenacea):

Section of female reproductive system in which eggs are produced. Paired, elongate, extending through most of thorax. Each ovary opens to exterior on sixth thoracic segment via oviduct [Stachowitsch, 1992].

(Order Euphausiacea):

Section of female reproductive system in which eggs are produced. Paired (connected anteriorly), located between heart and digestive tract, and extending through most of digestive tract. Each ovary opens to exterior at base of sixth thoracopod via oviduct [Stachowitsch, 1992].
