Spider, say (8)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
arachnid
(Other definitions for arachnid that I've seen before include "Spider or scorpion for example" , "Group including spiders and scorpions" , "One of species including spiders, scorpions etc" , "Harvestman, possibly," , "Incy Wincy Spider, say" .)
