Shrimps are apparently able to adapt their colour pattern to the background or to light conditions; this may explain why some specimens appear rather spotted, and not banded, while others present reddish-brown instead of blackish banding (Fig. 21).

In these two species, the variation affects not only the rostral length and shape (e.g., narrow vs. broad laterally, straight vs. slightly descendant), but also the degree of development of the inferior subapical tooth. The specimen from Channel Island near Darwin, Northern Territory (NTM Cr-013092) has the longest and most slender rostrum among the specimens examined (

Therefore, this feature is seen here as undergoing intra-specific variation. However, it would be most interesting to analyze the genetic structure of
