It turns out that snails, often confused with toads, are also well in advance in many scientific and social science explorations*, are prone to form male/male romantic attachments in which one partner eventually changes sex so they can settle down into normal married life with children.

* See The Wind in the Willows by Kenneth Grahame
'I wonder,' [Toad] said to himself presently, 'I wonder if this sort of car STARTS easily?'
I would not enter in my list of friends,
Who needlessly sets foot upon a worm.
An inadvertent step may crush the snail
That crawls at evening in the public path,
But he has the humanity, forewarned,
Will tread aside, and let the reptile live.
--- William Cowper
The year's at the spring
And day's at the morn;
Morning's at seven;
The hillside's dew-pearled;
The lark's on the wing;
The snail's on the thorn;
God's in his heaven --
All's right with the world!
--- Robert Browning
(I had to add a quote from Browning,
just because many don't realise that
snails weighed heavily in his notion
of the proper order.)
