Arachnids are further distinguished from insects by the fact they do not have cephalon ( head ) and the thorax, and is usually covered by a single, unsegmented carapace.

In the adult insect the head capsule is apparently unsegmented, though embryological studies show it to consist of six segments that bear the paired head appendages, including the mouthparts, each pair on a specific segment.

Above the rectum tract a large area of horizontal unsegmented muscle fibres is present, probably representing the unsegmented " Musculus caudofemoralis longus " of the tail base, the main retractor muscle operating on the thighbone.

Note : despite the fact that native processes written for INtime can only operate using unsegmented flat-mode addressing, it is possible to port and run some older iRMX applications that use segmented addressing to the INtime kernel.

For the unsegmented Stream ( includes content from all of a user's Circles ), each Circle has a " slider " configuration item with four positions : nothing, some things, most things, and everything.

The head of the leech that comes from an unsegmented region, is formed by the first set of micromeres derived from A, B, C and D cells, keeping the bilateral symmetry between the AD and BC cells.

These fish are highly variable in length, but an average length is 40.0 cm soft rays, 60 anal fin soft rays, two unsegmented dorsal fin rays, and a caudal fin with long median rays free at the tips.
39.
The view that the arthropod head must contain an acronal remnant has been shaken by the relatively recent revision of protostome phylogeny, which has dismantled the Articulata and placed the arthropods together with a group of unsegmented worms often referred to as the Cycloneuralia in the so-called Ecdysozoa.

There is a great deal of variation, however, to the extent in which the upper surface tissue of the rays crack : this tissue layer may also remain closely attached as a sheet over the unsegmented part of the outer wall with the part adhering to the rays variously cracked and sometimes finally peeling off in places.
