trunk

trunk

Postcephalic portion of body.

The postcephalic body of a crustacean, sometimes divisible into an anterior thorax and posterior abdomen.

Posterior of two divisions (tagmata) of body (head, trunk). Trunk may be considered to consist of thorax, abdomen, and postabdomen, whereby thorax refers to anterior appendage-bearing region of trunk, abdomen to (reduced) region posterior to trunk appendages, and postabdomen to recurved posteriormost region. Somite border indistinguishable in posterior region of trunk. (covered/not covered by valves).

Region of body posterior to head. Consists of thorax with 11 segments and abdomen with large and variable number of body rings; anterior region covered by carapace. Term is frequently applied due to poorly delimited border between thorax and abdomen.

Posterior of two divisions (tagmata) of body (head, trunk); consists of 10-32 somites (excluding telson), each bearing pair of appendages. Considered to basically consist of thorax and abdomen, although the two are indistinguishable.

Region of body posterior to head. Typically consists of 19 postcephalic segments (excluding telson), of which the first 11 represent the thorax, the last 8 the abdomen.

Region of body posterior to head (cephalon). Consists of 19 segments (excluding telson), of which first 8 represent the thorax, the last 11 the abdomen.

The postcephalic region of the body.

Entire region of body following head (cephalon); according to interpretation, may be subdivided into thorax and abdomen or maxillipedal somite and thoracoabdomen.

Region of body posterior to head; corresponds to thorax (and rudimentary abdomen). Unsegmented, typically bearing two pairs of appendages (thoracopods) and caudal rami. Entirely enclosed in carapace.

Term applied to region of body posterior to head (i.e., thorax and abdomen). Refers also to more expanded part of thorax posterior to neck in parasitic copepod.

Posterior division of body (cephalon, trunk). Consists of up to approximately 30 similar segments, the first (i.e., maxillipedal) being fused to head (cephalon), the second (= apparent first) being sometimes partially covered by head (cephalon), the last reduced and partially fused anal segment; each segment is produced laterally into pleurites and bears pair of biramous appendages.
