The 11 CA valves in the isopod Bathynomus doederleini receive varying patterns of innervation (Kihara et al., 1985), and the activity of the inhibitory nerve to the CA valve of the artery supplying hemolymph to the swimmerets is coordinated with the activity of the swimmerets themselves (Fujiwara-Tsukamoto et al, 1992).
Each LAA extends laterally for a short distance, then descends and arborizes to supply hemolymph to the abdominal muscles and the swimmerets (Wilkens et al, 1997b).
The DAA supplies hemolymph to the abdominal muscles and swimmerets through the segmental pairs of LAAs, and to the gut and gonads through a perfusion of small-diameter vessels that exit the ventrolateral wall of the DAA.
While an animal was walking, the swimmerets beat and the abdomen and chelipeds were held slightly elevated and extended.
