Known to occur at various depths from near the surface to 500 m, once recorded below 1000 m (Matthews, 1972). Sampling depth (Antarct., sub-Antarct.): 100-250 m. Overall Depth Range in Sargasso Sea: 0-2000 m (Deevey & Brooks, 1977, Station "S");
The original discription of the male is not known to us, but indicated in Bradford-Grieve & al. (1999) and Bradford-Grieve (1999 b, p.59, p.59, Fig.30 and remarks p.60).
For Mazzocchi & al. (1995, p.31), the species resembles H. oxycephalus, the latter of which is often recorded from Antarctic and sub-Antarctic seas. As discussed by Park (1988), the two species are practically indistinguishable; the only useful anatomical detail to determine acutifrons is the relatively shorter cephalic spine.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 1 corresponding to large sac-spawning carnivorous. | | | Last update : 07/12/2020 | |
