Harvestman (Leiobunum rotundum)
That small round single body contains not only its vital organs, but also some sort of brain and enough muscles to move eight long legs. Incredible!
These are insect feeders but they do not spin webs to catch their prey. They use speed and surprise - all coordinated through that tiny little control centre in the middle which also houses some pretty strong 'fangs' and a mouth capable of consuming insects larger than itself.
Isn't nature amazing?
