What is Street Creatures?  This is the game I run on Twitter every Friday. I’ve
collected all the past quizzes here in one place so you can either relive them, or play
them for the first time.

How does it work?  Provided are four, seemingly unrelated clues, that are all
connected by a wild organism that can be found in a city. Look at the four clues,
do some research, and when you think you’ve figured it out, click on ‘Answer’
to reveal what connects the clues, and how they are connected.

Follow me on Twitter to play #StreetCreatures live every Friday at 9am PST.

Quiz #74 Clues

Pala pala
Mountain beaver

Answer (Don't click until you've solved it)

Western Sword Fern (Polystichum munitum)

Pala pala:

Native Salish Sea children played a game with the sword fern’s leaves in which they took a breath and said ‘pala’ while tearing off a leaf, trying to get as many as possible in one breath and so the fern is also known as the ‘pala-pala plant.


Some ferns have a nifty device called neochrome which is a light sensor lets them make use of blue AND red light. Down on the forest floor, red light is more abundant. They stole neochrome…more about this story in my book!

Mountain Beaver:

Not a beaver at all, these are considered the most primitive living rodent and they like nothing better to eat than some sword ferns. They still live in Seattle in forests where there are sword ferns. 


Ferns have a complicated sex life. Mature plants are not sexual! Instead they release spores that land and sprout into gametophytes which contain the sex organs.
