30], the third and fourth pereiopodal endopods were equivalent to controls in length and segment number, but functional joints on these appendages were generally not seen until later (e.
The endopod of pereiopod 1 was morphologically postlarval in this stage as well, always being composed of the full complem ent of 6 segments, with the elbow-like joint between merus and carpus, and completion of the joint between the propodus and dactyl to form a functional chela.
These larvae appeared to be similar to the postlarva in other respects, except that the second pereiopodal endopod occasionally had 9 segments rather than 10.
In the first two cases, the sediment is passed on to the dactyli of the Mxp3 endopods as they comb through the setae that hold the sediment on the cheliped or P2-4.
When the Mxp3 endopods collect sediment, they start by pressing the dactylus and sometimes also the propodus into it (Fig.
Such large food objects are grasped by the endopods of Mxp2 and Mxp3 (Fig.
When carrying a small food item, the Mxp3 endopods bend posterio-medially to meet the endopod of maxilliped 2 (Mxp2 endo) (Figs.
Like the Mxp3 endopods, the endopods of Mxp2 can be used at the same time--when one is moving anteriorly the other is moving posteriorly--but th is is not the normal pattern.
During the sorting process, the Mxp2 endopods are held medially where they form a setal screen which also prevents particles from escaping ventro-anteriorly.
Grooming of an Ant1 starts with the appendage in question bending ventrally and both Mxp3 endopods moving dorsally (Fig.
The endopod of mature (vitellogenic) females is longer and wider than the exopod, and a mixture of plumose setae and long, thin simple (ovigerous) setae is present on the endopod.
The appearance of the setae (either plumose or a mixture of plumose and simple setae) attached to the endopod was studied under a light microscope.
