Although there are some minor differences at higher RMSs values, these are typically small and
can likely be corrected with a reasonable level of confidence (see Letessier et al., 2013). However,
there is less certainty where there are very few individuals observed for a given species, and where
length can vary greatly (such as for large sharks, e.g. Galeocerdo cuvier), thus making assumptions
about representative lengths problematic.
