Up to now, all the huntsman spiders that I’ve seen have been brown. Some were darker, others lighter, but basically brown. I was surprised to see this little one the other day:

It was quite small, for a huntsman, but still a good size spider. In real life, it appeared even more green than the photo shows. I had to Google it, to discover that indeed, green huntsman spiders are a thing. This one was in Allambie Heights, north of Sydney, NSW. I hope to see it again!
