Observations on natural diet and reproductive behaviour of an endemic snail Indrella ampulla (Benson

The posterior part of the foot was curled towards the left side of the anterior part of the other individual, reaching close to the posterior left dorsal lobe. [...] The phallus everts from the right side of the anterior portion of the head and curls along the opposite individual’s phallus, passing through its right lateral surface to reach the female organ in both individuals simultaneously. [...] Interestingly, the soft body of the hatchlings of the yellow morphs was all black, and they acquired the yellow colour as they matured. [...] As the individuals matured and grew, the mantle and parts of the soft body then changed in colour to yellow along with the foot region, while the shell remained brown with black patches (Figure 3(d)).
