Learn What Barnacles Eat
The marine creatures – Barnacles are the shell crustaceans in the animal kingdom with different types. You most probably have seen them attached to the ships, whales, lobsters, and turtles. When a group of barnacles is attached to the hull of a ship, they slow down the big watercraft.

Now you might be thinking why would they even attach themselves to hard, rough surfaces? Well, that’s because barnacles don’t like to move at all, so they attach themselves to surfaces.
Besides, these surfaces are hit with the current of water that brings them the food that they need! For that reason, barnacles are filter feeders – take food particles through the current of water! If you’re curious to learn “What do barnacles eat?” we’ll look at the types of diet they consume.
Insects and Animals
Just like any other shell-covered animal, barnacles have to feed themselves to grow their shell. Their diet consists of both animal and plant matter – especially the microscopic particles. They capture the prey for when it’s feeding time and begin consuming it through its feet. Surprisingly, barnacles eat with the help of their hair-like feet called cirri that function as both feet and mouth.
Because they feed on microscopic animals and other food particles, barnacles eat plankton. Barnacles eat phytoplankton – being their favorite food of all. But, they can also scavenge the dead matter. Together with these, barnacles eat meat and crabs.
Fruits and Plants
Due to their omnivorous nature, barnacles also feed on a variety of plants growing in the sea. And they won’t feed on fruits because it’s not part of their microscopic diet. That being said, barnacles eat plants, algae, zooplankton, and coral among other algae and plants.
How do barnacles eat?
Barnacles take up the food with the help of its hair-like appendages – Cirri. These appendages function as feeding fans to capture and filter food particles for barnacles. This cirral activity is a little complicated to understand.
However, barnacles capture more food once they are hit with water flow and spread their cirri to collect it. Using their cirri function, barnacles filter the water to search for food, especially the microscopic particles.
What fish eat barnacles?
Barnacles have predators that include whelks, starfish, mussels, and humans as well. Because barnacles have a soft body inside their shells, they are consumed and eaten by many predators. Besides, the sheepshead fish eat barnacles among other fishes and crustaceans.
What Barnacles don’t eat?
Among many things consumed by barnacles, there’s also a list of food that isn’t the preference of barnacles. Barnacles don’t eat wood, whales, and turtles even if they are attached to their rough-surfaced body or shells. While many would think that barnacles eat wood because they attach to ships, it’s not the case. They attach themselves to travel to other places while collecting food particles. Together with these, barnacles don’t eat fish, mussels, seaweed, copepods, limpets, and oysters.
