On low tide days, our city sends our volunteers to monitor the activity in the tide pools. They are also there to keep away those humans who are likely to want to take a sea star home, an occupied shell, or some other live souvenir.
Pictured above is a shark egg case that one the volunteers showed us. Neither one of us had ever seen one before. We would have picked this up as something to recycle because it felt like a leathery plastic. Here is the description from Wiki,
"Shortly after internal fertilization, the fertilized ovum enters the partially formed egg case located in the oviduct.After the ovum enters, the rest of the egg case forms around it. Shortly after the egg case finishes developing, it is deposited outside the body; common locations include kelp forests and rocky seafloors. Egg cases are typically produced in pairs, each with one fertilized embryo inside, with the exception of a few species that produce egg cases with more than one viable embryo..."
These egg cases are shaped like an auger (where Ron's fingers are holding it). It is the perfect attachment to rocks or plant matter, as are those curly strands to keep the embryo in place...
