A histioteuthid ...
- occuring in the North Pacific with 4 series of arm IV photophores.
- Head photophores with type 2b pattern (e.g., 2 photophores in Midline Series, 4 in Basal Arm IV Row).
- Arms IV with 4 longitudinal series on arm base.
- Rings on enlarged median suckers of club manus with 28-34 small, sharp, narrow teeth around entire margin.
CommentsMore details of the description can be found here.
Species of the corona-group are distinguished by the following characteristics:
- Type 2 head-photophore pattern (e.g., 2 Midline Series photophores, 3 or 4 Basal Arm IV Row photophores and no rogue photophore) .
- Basal Row with 7 photophores.
- Right Basal Series present.
- Arms IV without separate series of compound photophores at arm tip.
- Compound photophores on anterior half of ventral mantle uniform in size.
- Suckers with smooth rings on arms I-III except at distal ends and occasionally on basal suckers.
- Suckers of arms IV with dentition.
The following table compares differences among members of the corona-group. H. cerasina and H. corona are very similar but occupy different oceans.
