STREET CREATURES QUIZ

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 #53 Clues

Anal siphon
Metalloprotein
Epipodium
Arctonoe vittata

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

Keyhole limpet (Fissurellidae)

 

Anal siphon:

Keyhole limpets are NOT true limpets, one clue to their difference is in the reason for their name, the hole on the top. This serves as a hole for the anal siphon, which is where they spew their waste from.

Metalloprotein:

Keyhole limpet hemocyanin (KLH) is a metalloprotein that keyhole limpets carry in their hemolymph. It’s extracted from Megathura crenulata and used in research to make antibodies and possibly a vaccine for some cancers.

Epipodium:

The grooves between the keyhole limpet’s mantle and foot are called the epipodium and is where their tentacles are found.

Arctonoe vittata:

This small polychaete worm lives a symbiotic life with several different marine invertebrates, including the keyhole limpet. When a sea star tries to attack the limpet, the worm bites the star’s feet.
