Balanus variegatus   Darwin,  1854 (Barnacle)
Organism information awaits expert curation
Class: Maxillopoda

Image copyrights: Museum Victoria Australia

Size: Maximum carino-rostral diameter 22 mm; height 15 mm.

Shell usually conical. When growing in aggregation assumed cylindrical shape; radii usually wide with fine transverse striations and oblique summits; orifice relatively larger and more prominently toothed in aggregated specimens.

Opercular valves: Adductor ridge of the scutum high and moderately longer resembling the specimens from Bombay described by Karande and Palekar (1966). Internal surface of tergum strongly roughened particularly the carina1 side; spur end usually bluntly pointed.

Inner maxilla: Lower pair of spines strong, or very strong, sometimes moderate, occasionally on slight prominence.

Cirral appendages: The characters closely agree with the description of Henry and McLaughlin (1975) except for one important character. According to Henry and McLaughlin (1975) the absence of erect teeth below the posterodistal angles in cirri III to VI is considered as one of the characters differentiating Balanus variegatus from Balanus reticulatus which bears the erect teeth.
