Genus Acanthophrynus

Mexican giant whip spiders, amblypygids, and among the most alien-looking animals anyone keeps. A. coronatus is the species.

No venom, no silk, no bite worth worrying about. They catch prey with spined raptorial pedipalps and navigate with an enormously elongated first pair of legs used as feelers. Flat, nocturnal, and they want vertical cork bark and height, particularly at molting, since they molt hanging and a fall is fatal.

Mexican material moves irregularly and captive breeding is inconsistent, so supply is thin and prices sit above what the husbandry difficulty suggests. This is a genus where the constraint is finding one at all rather than affording it.
