Guuuurl, I **love** that flower

Question

I can sit on your head, or maybe your hand;
I look like I came from a different land.
Find me in water, or perhaps above,
I'll give your prized flower some lovely, lovely love.

I can be a snack, but I'd prefer if you don't,
in fact, I'd prefer to stay unknown.
My cousin of mine, to make a correction:
He's simply ain't got no protection!
I can be male, or I can be female-
but I'll still remain a simple little* _____.

*_{In most cases.}

Answer 1

Are you

a snail?

I can sit on your head, or maybe your hand;

they're small enough to do so, also this could be a Gary reference

I look like I came from a different land.

they do look pretty weird

Find me in water, or perhaps above,

there are sea snails and also tree snails

I'll give your prized flower some lovely, lovely love.

snails love to eat flowers

I can be a snack, but I'd prefer if you don't,

did you see that 'S' car go??

in fact, I'd prefer to stay unknown.

they'd probably rather not be cooked in a white wine and garlic sauce, with or without melted cheese on top

My cousin of mine, to make a correction:

a slug, possibly?

He's simply ain't got no protection!

slugs don't have shells

I can be male, or I can be female-

snails are hermaphrodites, and can act as male or female for the purposes of reproduction

but I'll still remain a simple little* _____.

and snail rhymes with female!
