Or maybe hard plastic in a "hydrodynamic" (if their is such word) form that could withstand the currents.
So one possibility is that the melanosomes got bigger during later penguin evolution as the birds became better underwater swimmers and needed a more hydrodynamic covering.

By contrast, Deep Flight Challenger, a one-person, high-performance, experimental, prototype submersible designed by Hawkes, looks more like a plane and uses hydrodynamic force to propel the craft down.
Fancy a trip to see the Titanic? Super-subs will take tourists to the bottom of the sea
But like hydrodynamic shapes among vertebrates, evolution is constrained by the inherited architecture and by what works in those domains, hence convergence in some cases, and a rich diversity in others.
The convergence of the hydrodynamic shape among vertebrates is currently thought to be due to the environment/similar niche/even interactions:
Zach: Yes, similar problems with a small number of solutions leads to convergent evolution, like the convergence between the hydrodynamic shapes of the vertebrates fish and dolphins.
Like its natural archetype, the AquaPenguin from Festo has a hydrodynamic body contour.
Yes, similar problems with a small number of solutions leads to convergent evolution, like the convergence between the hydrodynamic shapes of the vertebrates fish and dolphins.

bilby commented on the word hydrodynamic
"Marine biofouling is the process in which organisms such as barnacles problematically colonize underwater surfaces. When it happens to the hulls of ships, the vessels become less hydrodynamic, having to burn more fuel in order to move through the water."
