Comprehensive DescriptionRead full entry
This species was described from a single specimen (ZMH 5170, 157 mm SL), collected in the western Indian Ocean southwest of Socotra Island near the entrance to the Gulf of Aden in a depth of 290-190 m (Kotthaus, 1974), and has been reported from the Gulf of Kutch, an inlet in the northeastern quadrant of the Arabian Sea on the west coast of India (Manilo and Bogorodsky, 2003) (see Figure 9). Three small specimens (USNM 326398, 40-47 mm SL) of Symphysanodon ZBK , collected by prawn trawl in 78 m off Somalia in the Gulf of Aden, may be representatives of S. andersoni ZBK (see Figure 9). Unfortunately, none of the small specimens is in good enough condition to accurately determine the most critical character (number of lateral-line scales) needed for identification as that species. Nevertheless, the presence of parapophyses on the first caudal vertebra in the holotype of S. andersoni ZBK and in the three small individuals suggests that the four specimens are conspecific (see below).
