Trying to see what sex each of these are.

Hello,

1 is a male
3 is a female.

The other two it is hard for me to distinguished with the pictures posted.
These are my opinion and I could be completely off base here.

Thank you.

1 is clearly male, judging by hairy rear part of the body
2 looks like female to me, going by body shape (wider than widest part of the head)
3 and 4 look to be male from shape but appear to lack the odontes on the body, so not sure about these, but I think most likely male

Given that 2 and 3 appear in reverse order in the post, it may well be that me and previous poster agree on which one is the female, because maybe they called number 2 number 3, if you see what I mean.

Although it is a bit difficult to distinguish, I think the number 3 is male because the head and dorsal fin look more like the male than the female L397.

What does a male's dorsal fin look like?
