Lampanyctus simulator 



Wisner, 1971 



Fig. 181 — Lampanyctus simulator, holotype. female, 73.3 mm. From Wisner (1971. p. 



52, fig. 7). 



Description 



D. 13 (12-14); A. 18 (17); P. 12-13; AO 6 (5-7) + 8 (7), total 14 (13-15); gill rakers 5 (4) + 1 -H 

 11-12, total 17-18 ( 16); vertebrae 36 (35-37). Correlated counts of AO photophores and of gill 

 rakers are given in Table 36 and are compared with similar counts for L.jordani. 



Lampanyctus simulator is similar to L.jordani, primarily because of the extra-pectoral 

 photophore just above and behind origin of pectoral base (an organ previously thought unique 

 to L.jordani ). Also, the second and third AOa photophores are often slightly elevated in a 

 weak imitation of the much greater elevation of these two organs in L.jordani, as delineated 

 by Wisner (1970b). Other similarities and differences are discussed below. 



Size: To about 95 mm. 



Least depth of capture: To 200 m at night. 



Distribution: L. simulator is thus far known from only 13 specimens from a restricted area
