The study objectives were to find morphometric variables of otoliths to identify the two species and relate ecomorphological characters of otolith and eye diameter to the depth distribution of each species. The otoliths of the two species are very similar, although significant differences in shape, otolith height and weight and the <i>sulcus acusticus</i> area were detected. The ratio between eye diameter and cephalic length (<i>ED:CL</i> ratio) was also significantly different. In both analyses <i>A. carbo</i> obtained higher values, which suggests that <i>A. carbo</i> and <i>A. intermedius</i> live in different spatial niches, and that <i>A. carbo</i> inhabits deeper waters. The ratio between the sulcus and otolith areas (<i>S:O</i>) was low compared to other fish species, which suggests that the hearing capacity of <i>Aphanopus</i> spp. is adapted to low frequency sound. This adaptation may be related to the oceanographic conditions in which these species live, and in particular to the characteristics of sound transmission in the “SOFAR channel”.}, number={4}, journal={Scientia Marina}, author={Tuset, Víctor Manuel and Piretti, Silvia and Lombarte, Antoni and González, José Antonio}, year={2010}, month={Dec.}, pages={807–814} }
