About Turbo militaris Reeve, 1848
Description: The shell of Turbo militaris ranges in length from 60 mm to 100 mm. This species produces large, solid shells with rounded whorls. External shell morphology varies widely based on whether spines are present or absent. Two distinct morphs exist: a smooth morph, which only has growth striae near the lips, and a spiny morph, which has two rows of open-fronted spines on the body whorl. Intermediate forms with morphology between these two extremes also occur. The presence and prominence of the anterior canal also differs between morphs; this structure is almost non-existent in smooth forms, but prominent in spiny forms. Both the smooth and spiny morphs can be found growing together at the same site. The aperture is subcircular, with a pearly white interior. The simple outer lip is fairly thin. The shell's color pattern consists of spiral brown or green bands laid over a fawn-colored background. The columella is smooth, and bears a white callus with green edges. The operculum is subcircular and calcareous, with an outer surface that is white with a faint green tint. Distribution: This marine species is found off the coast of Australia, ranging from North Queensland to New South Wales.
