During the TED conference we had a party at the Aquarium of the Pacific where I was LITERALLY in my element. In the moments where I was not talking to people about whales and the ocean, I was taking in the wonderful sights. Here is an exciting one I would like to share with you all.
The little shark egg sacs are slit on one side so visitors can get a glimpse inside. Watch how the tiny critter moves while feeding on its companion yolk sac which supplies it with nutrients. They even have egg sacs of different ages so you can see growth......
....and what does this have to do with mermaid's and their purses? the egg cases are coloquially known as mermaid's purses or devil's purses. Click this link for more! http://en.wikipedia.org/wiki/Egg_case_(Chondrichthyes)
