• Sea Stars do something called external reproduction through a process known as broadcast spawning.
• In two hours a female Sea Star can release more than a million eggs.
• Broadcast Spawning usually takes place during the spring and end of summer.
Development of Sea Stars
It can take from about two years to five years for a Sea Star to reach adulthood. Depending on the type of Sea Star, some can life for 10 years after reaching adulthood and some can life for around 35 years after reaching adulthood.
Once the Sea Stars eggs have been fertilized they develop into planktonic larvae.
This stage of development leaves the plankton very vulnerable to being eaten, so the proper environment is key!
