Spawning feather duster worm

As the A block Marine Science second years were busily writing their practice IB exam this afternoon, a feather duster worm (Eudistylia vancouveri) was busily spawning in our seawater table.

The photos below were taken after I moved the tube worm from the plastic container it was in initially. When the worm withdrew it was like a volcano of sperm!  And then the worm slowly re-emerged…

We did have a look at the sperm under a microscope and saw that they were very active little swimmers!
