Acorn Barnacle

Acorn Barnacle Facts

• Acorn barnacles live along rocky shores throughout the north Atlantic and north Pacific oceans.
• Once an acorn barnacle attaches as an adult, it surrounds itself with a strong shell that provides it protection from predation and allows it to trap some water during low tide.
• Acorn barnacles live in the intertidal zone (the area between the high tide and low tide levels) and therefore needs to be able to survive long periods outside of the water. The shell can be closed tightly in order to prevent it from drying out.
• After they attach and build their little houses, acorn barnacles filter feed small plankton and other particles from the water using their modified legs.
