Barnacles are filter feeders. Adult barnacles have appendages that reach out and collect food. The larvae and adult barnacle eat diatoms, smaller plankton, and detritus.
Can barnacles survive out of water?
Some barnacles can survive long peroids out of the water. For example, Balanoides balanoides can go six weeks out of the water, and Cthamalus stellatus has been known to live for three years with only brief submergence one or two days a month.
Should you remove barnacles from turtles?
Parasitic Organisms. All barnacles increase surface drag and decrease the overall hydrodynamic shape of the turtle. Barnacles can be pried off with a variety of tools, but care should be taken with those that have damaged the shell. These should be removed with care so as to not create further injury.
What is the purpose of barnacles?
Because they are filtering organisms, they play an important role in the food chain. Barnacles are suspension feeders, consuming plankton and dissolved detritus suspended in seawater and are therefore essential in cleansing that water for other organisms. They are also a food source for these animals.

Figure 8.2 The intertidal distribution of adults and newly settled larvae of Balanus balanoides and Chthamalus stellatus, with a diagrammatic representation of the relative effects of desiccation and competition.
How does a Balanus live in the water?
The active animal can only be observed within the water when the shell opens and the barnacles expose two branched appendages ( cirri ) regularly hitting the water to catch food. They mainly feed on plankton . These barnacles can be found in coastal areas at low shallow depth, although they can also be seen living out of the water.
How are Balanus and Chthamalus alike and different?
Thus, Balanus and Chthamalus compete. They coexist on the same shore but, like the fish in the previous section, on a finer scale their distributions overlap very little.
How big is the shell of a Balanus?
The size of these shells ranges from 5 millimeters to 10 centimeters. They take the form of a cone consisting of six plates fixed on the rocks. The active animal can only be observed within the water when the shell opens and the barnacles expose two branched appendages ( cirri ) regularly hitting the water to catch food.
