These characters vary slightly, in detail, at the generic and specific level but are basically the same for all members of the two families as follows. The basis of pereopod 5 is articulated proximally with the basis of pereopod 6 by means of a small knob, located medially, near the proximal anterior corner of the basis of pereopod 6, which articulates in a groove on pereopod 5, produced by an elongate process on the medial surface of the coxae and a small, adjacent knob on the basis (

). The basis of pereopod 5 has a bevelled anterior margin that fits under the coxae (1–4), and distally in a groove under the head, next to the second antennae. The posterior margin of the basis of pereopod 5 overlaps with the anterior margin of the basis of pereopod 6, which is bevelled to ensure a neat overlap. The posterior margin of the basis of pereopod 6 has a distinct notch (or shoulder) for urosomite 1, followed by a telsonic groove, which neatly accommodates the double urosomite and the telson. Distal to the telsonic groove is a locking mechanism for opposing pereopoda, consisting of a ridge/groove arrangement,

In addition, the distal margin of the basis of pereopod 6, distal and anterior to the locking mechanism, is grooved so that the margins of opposing pereopods can overlap thus assisting in holding them together. The head has a central ‘beak’, which fits neatly with the antero-distal corner of the basis of pereopod 6 (see

B). Finally the epimeral plates have lateral ridges, which fit neatly against the proximal part of the posterior margin of the basis of pereopod 6, when the animal is curled. Thus, these animals are able to achieve an almost smooth, tightly packed, globular shape. The reasons for adopting this habit are not known. A spherical shape would sink more rapidly, and this may assist in the avoidance of predators, or in diurnal migrations.
