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.

Kim
Hydraulic pressure

Jumping spider AKA the Salticidae family
Book lung:
This is the respiratory organ in most arachnids. Located in the abdomen, they are composed of plate like structures filled with haemolymph. Air circulates between them exchanging gases.
Kim:
Kim is a Regal Jumping Spider (Phidippus regius) that was trained to jump on command during a study looking into the mechanics of how these spiders jump. Read the study.
Hydraulic pressure:
It was thought, before the above study, that jumping spiders relied on hydraulic pressure in their legs, not their muscles, for their extraordinary leaps. However they found Kim didn’t rely on hydraulic pressure. Read the study.
Telescope eyes:
Jumping spiders have two large principal eyes and two smaller secondary eyes. The principal eyes are highly acute and are described like Galilean telescopes. These eyes are so acute they can see the moon and Andromeda. Read more.
