5 Facts About Sea Urchins

5 Facts About Sea Urchins

Cape Clasp is on a mission to #makewaves for marine life causes, and that includes spreading awareness about our ocean friends! This week, we're focusing on the sea urchin that can be found in every ocean all around the world!

THEY LIVE IN ALL 5 OCEANS

The 950 different species of sea urchins live in water of all temperatures, warm or cold. Some species prefer to live in the shallows or among kelp forests, while others find their home in deep, rocky seabeds. 

THEIR DIET IS FULL OF DELICACIES

Sea Urchins aren’t too picky when it comes to what they put in their stomachs. Their main source of food is algae from the corals, but some species prefer to grub on mussels, barnacles, sea sponges, and even dead fish. What the sea urchins eat depends on where they live and what’s available! They’re pretty easy going.

THEY PREFER TO REPRODUCE IN THE SUMMER

Mama sea urchins release millions of eggs that are coated in jelly, and keep them close by using their spines to hold on to them. Within half a day, a swimming embryo forms and swims free until it’s a juvenile and sinks to the bottom of the sea. These sea urchin kids reach adulthood within 5 years! 

THEY CAN GIVE HUMANS BOO-BOOS, BUT THEY DON’T MEAN TO

Our friends, the sea urchins, are non-aggressive and are slow-movers (they use their spines and a row of tube feet to walk around), so they don’t injure humans on purpose. Us humans tend to get injured by the urchins when scuba diving/swimming and accidentally brushing into them, or when a person accidentally steps on one - which can lead to a spine breaking off and puncturing!

TENS OF MILLIONS OF URCHINS VISITED THE WEST COAST

Sea urchin population has grown by 10,000% in the last five years, which saw purple sea urchins ravage the coasts of California and Oregon in 2019. Scientists believe it could take 15-20 years to remove almost 100 million pounds of sea urchin from one large Oregon reef alone!
