Is there any race which, without applying any external option (e.g. feat, template, spell),
qualifies as an elf for prerequisites (read: is named as some kind of elf, has the elf subtype, and/or has something like half-elves’ elven blood allowing the race to qualify), and
is not humanoid (read: has one of the other creature types)?
Official material (WotC-published or WotC-approved, e.g. Dragon, Dungeon, Oriental Adventures) only. Templates not allowed even if printed that way (e.g. if someone wrote an article about half-dragon elves and wrote up racial stats for them with the half-dragon template baked in, that doesn’t count—but a draconic elf that isn’t made from a template could work). LA +0 races vastly preferred.
