They're creepy and they're yikey
Mysterious and spiky
We'd have to say CRIKEY!
It's the SEA URCHIN!

IMPRESSIVE SCIENTIFIC STATS ?
Name: Echinoidea sp. Size: 10cm Lifespan: up to 100 years (wow!)

WHERE THEY HANG ? These weird and wonderful critters are another shoreline dweller you may be lucky enough to find at lowtide.

SUPER COOL FACTS ? Sea urchins eat algae with a scraping feeding structure called Aristotle's lantern.

LEAVE NO FOOTPRINTS ? Yikes is right - sea urchins have sharp spikes that can be venomous so definitely hands off!
