Barnacles on lobsters can negatively impact their health and survival by increasing drag, making it harder for them to move and find food. This can lead to decreased energy levels and vulnerability to predators. Additionally, barnacles can compete with lobsters for resources and may even cause infections or damage to the lobster's shell.
