Barnacles are arthropods of the subclass Cirripedia in the subphylum Crustacea. They are related to crabs and lobsters, with similar nauplius larvae. Barnacles are exclusively marine invertebrates; many species live in shallow and tidal waters.
Some 2,100 species have been described. Barnacle adults are sessile; most are suspension feeders with hard calcareous shells, but the Rhizocephala are.

Smaller than a millimeter, with compound eyes but no mouth, the late larval barnacle is highly specialized for sensing color, texture, water speed and temperature, and chemical signals. Barnacles are sessile marine crustaceans closely linked to crabs, lobsters, and shrimp. They are part of the subclass Cirripedia, which falls under the larger subphylum Crustacea.
Encased in a cone-shaped shell composed of six calcite plates and a hinged lid made from four additional plates, barnacles are well. Barnacles like places with lots of activity, like underwater volcanos and intertidal zones, where they reside on sturdy objects like rocks, pilings, and buoys. They also attach to moving objects like boats and ship hulls and whales.
Barnacles can be a wide range of colours, from pink, yellow, orange, green, brown, black, white, or cream. Their colour is dependent on the environment so they can blend in and hide from potential predators. Barnacle defined and explained with descriptions.
Barnacle is a small crustacean that attaches itself to marine objects such as rocks, and boats. Barnacles spend the rest of their lives in this position-head down and feet up. The Acorn barnacle shell width ranges from 1/4 to 1/2 inch, and their color varies from white to light brown.
They are volcano-shaped; that is, the shell has a larger base that tapers at the top. Acorn barnacle to 30 mm diameter, shell plates with longitudinal red and white stripes; mantle margin with orange, blue, yellow, & red. A barnacle looks like a mollusk with shells, having a size from about 1 to 7 centimeters across.
A barnacle has 6 overlapping shell plates that are grayish-white in color but some species can be black, cream, or yellow. Barnacles body color description: Brown, gray, and white. skin type: The Maxillopoda has a hard, chitinous exoskeleton with a rough, bumpy texture.
Its body is covered in small, spiny protrusions that give it a prickly feel. Strengths: Mobility, Adaptability, Resilience, Complex Reproduction, Ability to Survive in Extreme Environments.
