After looking at the Histioteuthis images over at Tolweb, my answer to my own question is "probably not." Even in the glare of submersible lights, Histioteuthis still clearly shows its mantle & arm photophores. Different Histio species have photophores of varying prominence and reflectivity (sometimes because of sexual dimorphism), but they're still hard to miss.Clem said:could photophores on the mantle be obscured by the bright wash of lights from the ROV?
An e-mailed plea for help is currently making its way through hawaii.edu. Should have an answer soon.
