Barnacle is a tradesman of the old school, who thinks the foppery and extravagance of the "Cockney" school inconsistent with prosperous shop-keeping.

The young barnacle just from the egg is a six-legged, free-swimming nauplius, very like a young prawn or crab, with a single eye.

A barnacle is another example of degeneration through quiescence.

As a baby, the Barnacle is a free swimming creature.

The barnacles are crustaceans related most nearly to the crabs and shrimps.

All its wonderful changes, and the way its body is made, tell us plainly that the Barnacle is actually first cousin to the Crab, Lobster, Shrimp and Prawn!
