| | Chesapeake Bay Program - Barnacle |
 | | There are two major groups of barnacles: Balanomorpha, or acorn barnacles, which attach directly to a firm surface, and Lepadomorpha, or goose barnacles, which live in the ocean and attach gregariously to floating objects by a long purplish-fl, rubbery stalk. |
 | | The bay barnacle is white, about 1/4 inch high and 1/2 inch wide, similarly constructed, preferring to attach to rocks, pilings oyster shells and other hard-shelled animals in brackish estuaries, in a wider range of depths, from shallow water to 120 feet deep. |
 | | Barnacle larvae are distinguished by two stages, the nauplii stage, in which the larvae appears to be triangular and resembles the larvae of a copepod, with two small spiky appendages. |
