Barnacle

The barnacle is not what you may think No mollusc this, no limpet dull and drab It's lack of adult movement hides the link To cousins like the lobster and the crab. Hermaphrodite, a male and female phase Alternate, and thus its offspring make It's lifecycle is one which should amaze What follows are the forms that it will take. Nauplius. Expelled and floating free Small and mobile, soft shell on its back It swims with other plankton in the sea Bottom of the food chain: just a snack. Cyprid. In this stage it does not feed It only searches with a sole intent To find the roost and friends that it will need Where it can stick itself down with cement. So here we are: the adult that we know Settled down and to its choice home bound Mature it still has those wild oats to sow Priapically, it still can get around.
