where specimens were observed with numerous long, few short, or absent digitiform branchiae. Pulling on both digitiform and subulate branchiae of both live and dead specimens resulted in breakage of the structure at various positions along their lengths and left ragged, torn edges. This contrasts with the removal of palps and elliptical lobe-like branchiae, which always come away from the body at the base and leave a regular, sealed scar.

, like others in the clade, swims by lateral undulation of the body coupled with expansion on the power stroke and contraction on the recovery stroke of the chaetal fans. Observations of parapodia removed from the animal suggest that this expansion and contraction of chaetal fans can be attributed to passive mechanical mechanisms, not requiring musculature. Swimming was observed to be both forward and rearward, which was difficult to distinguish unless the ROV was completely still and camera zoomed in enough to identify the anterior end. Animals were seldom observed

holotype. A, ventral view of posterior portion and twisted laterodorsal view of anterior portion upon recovery from the remotely operated vehicle. Arrow indicates an attached bomb. B, scanning electron micrograph of notochaeta tip; inset, differential interference light micrograph of several notochaetae. C, parapodium with notochaetae on right and neurochaetae on left. D, scanning electron micrograph of neurochaeta tip; inset, differential interference light micrograph of neurochaeta. E, dorsolateral view, anterior fragment of the preserved specimen showing palps, subulate branchiae (sb indicates left lateral branchia), peeled away gelatinous sheath around bases of chaetae, and the outgrowths of body wall supporting the two posterior-most elliptical branchiae scars (arrows). F, right lateral view of head. G, ventral view anterior fragment of preserved specimen showing gonads in chaetigers 4–5 (arrows), posterior fold of left nephridium (n), buccal organ, coiled palps, shape of the left lateral subulate branchia (sb), and the dark gut wall. H, illustration of image in F showing location of features. Abbreviations: 2, second elliptical branchia scar on nephridiopore papillus; bo, buccal organ; lsb, lateral subulate branchia; msb, medial subulate branchia; n, nephridium; np, nephridiopore papillus; nu, nuchal organ; p, palp. Scale bars: B = 50 Mm, C = 1 mm, D = 20 Mm, and E = 3 mm.

rearward escape response is also consistent with use of anteriorly located, autotomizable, bioluminescent decoys by removing the bulk of the body away from the released body part or decoy.

The first pair of elliptical branchiae differed slightly from all other pairs in that the first pair was always smaller than, or the same size as, the smallest bomb found on an individual. The second to fourth bombs varied in size; this was assumed to be because of regeneration of previously autotomized bombs. Manual stimulation of animals at any point along the body or head resulted in release of a bomb or two, which immediately produced green bioluminescence. Further stimulation would result in release of additional bombs if available. Bioluminescence was seen as a steady glow from bombs that had been autotomized. Bombs that were separated from the animal could be triggered to produce light again by gently squeezing them with forceps. The glow of an individual bomb lasted several seconds.</paragraph>
