GARTNER ET AL.: LANTERNFISHES 



as newly metamorphosed through juvenile stages 

 (Table 3). The remaining 11 species showed a rela- 

 tively complete ontogenetic series. With the excep- 

 tion of Hygophum reinhardtii, no individuals of the 

 26 uncommon species approached the maximum size 

 recorded for these species (Nafpaktitis et al. 1977). 

 During the day, most species were found between 



300 and 700 m, except for Lampanyctus cuprarius, 

 L. nobilis, L. tenuiformis, and Taaningichthys 

 bathyphilus, which generally were captured deeper 

 than 600 m. Nocturnal vertical patterns showed that 

 all uncommon species except Taaningichthys, a non- 

 migrator, entered upper mesopelagic or epipelagic 

 depths at night. Gonichthys cocco, Myctophum
