habitat |
factor |
Type of habitat where the crustacean lives ("marine", "fresh", "brackish", "terrestrial"). Default should be what is listed in WoRMS, unless the source document indicates otherwise.

sex |
factor |
Sex for which SM50 is being estimated (M, F, B = both separately, C = both combined, NS = not specified). Note that sometimes size at maturity will be estimated for both sexes but for females will be done using ovarian staging or similar physiological methods, while allometric data are used for males. If estimates of SM50 are not derived for the females besides a normal maturity ogive, this would only count as "M" |
