Fig. 3. Variation of coloration. (A,B) Body areas chosen in juveniles (A) and adults (B) for comparison of coloration. Frames indicate dorsal posterior (A) and posterio-lateral part of the carapace (B). (C–F) Areola (marked by white lines) of four stage-3 batch-mates, showing marked differences of pigmentation among individuals. (G–J) Pigmentation pattern of same specimen in juvenile stages 2 (G), 3 (H), 4 (I) and 5 (J), indicating that an existing pattern is not abruptly changed by moulting but gradually elaborated by addition of chromatophores. (K–M) Colour pattern of posterio-lateral carapace area of same adult at time of first reproduction (K), 124 days and 2 moults later (L), and 642 days and 6 moults later (M). The marmoration motifs are enlarged and modified with time but are still recognizable after more than 21 months. Scale bars, 2 mm. (N–Q) Colour patterns of posterio-lateral carapace area of dam B (N) and three mature daughters of the same batch (O–Q). Note striking differences in marmoration among all individuals.
