Found another book I want... titled "What on Earth?"
It's not a really new creature, but I don't recall seeing it before.
Long-neck assassin spiderBizarre Assassin Spiders Discovered in Madagascar
With its fearsome appearance, poisonous bite, and deadly hunting skill, this newly discovered creature lives up to its name: assassin spider.
The spiders stab their prey with their giant jaws, which are barbed at the ends with venomous fangs. To be able to lift their outsized jaws, the assassins evolved elongated necks, giving the spiders a unique ability to strike from a distance.
But arachnophobes can relax: Assassin spiders are a mere eighth of an inch (two millimeters) long and are harmless to humans.
