Naupliar Stages of the Coral Inhabiting Barnacle Savignium Milleporum (Darwin) (Cirripedia: Pyrgomatidae) from the Gulf of Eilat, Red Sea
Abstract:The six naupliar stages of the coral inhabiting barnacle Savignium milleporum (Darwin) are described, based on larvae reared in the laboratory. An 82.6% increase in total length from stage I to VI nauplii was coupled with an 83.3% increase in width. Development of lateral abdominal spines followed closely the typical balanid pattern, while the three lobed labrum was setose at all stages. The number of setae on the antennule increased from eight in stage I nauplii to 12 in stage VI individuals, on the antennae, from 15 to 19, and on the mandible, from 14 to 18. Details of the setulation are summarized using alphabetical formulae. Deviation of setation from the “typical” balanid pattern are discussed.
