Hi all, I'm researching on HISTIOTEUTHIS species for beak morphometry on different life stages, and I would like to differentiate between MALES and FEMALES. I have extracted the mantle cavity organs, including the stomach, glands, and weird white and pink organs I recognise as the GONADS. BUT I find it difficult to see if they are male or female. I've seen some general diagrams for cephalopods, but I dont recognise such structures in Histioteuthis. Can anyone give me any tip, diagram, photography to show me the generic difference in squid gonads please? PD. Its quite of an urge, I'm presenting the seminar in 2 weeks and I have to process +60 gonads :S PDD. If in addition to this someone could give me a clue on visual recognition of sexual maturity, it would be great! Thank you.
