Antenna II comparisons and embryonic development comparisons in cave and surface Asellus aquaticus. (A) Absolute antenna II size comparing 15 surface hatchlings and 15 cave hatchlings. Two tailed Mann-Whitney U-test, P = 8.979 × 10−5. (B) Absolute body size comparing 15 surface hatchlings and 15 cave hatchlings. Two tailed Mann-Whitney U-test, P = 5.619 × 10−5. (C) Relative antenna size comparing 15 surface hatchlings and 15 cave hatchlings. Wilcoxon Rank Sum P = 0.9349. (D) Article count in right antenna II of 20 surface hatchlings and 20 cave hatchlings of Asellus aquaticus. PermTS P = 1.482 × 10−5. (E) # of articles versus antennal length in cave and surface hatchlings. (F) Duration of embryonic development in 40 surface and 20 cave embryos. Mann-Whitney U-test, P = 0.2622. ***P < 1 × 10−4, NS: P > 0.05.
