Maybe in the fishmen/merfolk it's the men who give birth ^^ that would explain for shirahoshi… Since well Oda said they give birth the same way as humans (aka mammals) but what if the queen just gave an egg to Neptune and he just placed it in a pouch like a kangarou or something...
Anyway great chapter, but it really felt short :/ and compared to the last one here wasnt that much in it that we didnt already know.
Someone mentionned that the one who killed Otohime will surely be the main villain for this arc. If i remember correctly the one who killed her was the former VDD (since there've been alot of VDD captains) so my presumption on that is that he died maybe like someone suggested rippe in half by neptune himself
Neptune did speak as if he had been in battles in the past so maybe there was a huge battle between Neptune with the VDD pirates.

(way too old to do this sort of thing, so he has done it before ^^)
Maybe even on SA and with the Sun pirates involved as revenge on VDD for killing the queen that ultimately everyone loved. And thats how Tiger Fisher got injured and nobody could help him because of the rare fish blood type he had. If this turns out to be true it could explain the hatred Arlong had for humans after seeing how no one would help not even among the fodder un SA. And after seeing so much death Jinbei repented and vowed to continue shirahosi's will. So he made a deal with the government to disband the sun pirates in exchange for some peace to be regained after all the deaths and tragedy. So FI was somehow safe, the menace of sun pirates was gone so the WG was happy, but at the same time maybe Jinbei felt someone needed to continue what fisher tiger was doing so he let arlong go or maybe he told him to got somewhere and conquer the humans or something… while he was left trapped in the shichibukai position unable to do anything.
And of course with time he saw that otohime's way were better than the violent ways and came to regret letting arlong go to wreak havoc in east blue.
XD so long don't read ...
