Electrona antarctica; a the relationship between dry weight (DW) and energy density g⁻¹ DW including the parameters for the linear regression of ln(y) = a + bln(x), and the corresponding power function y = x^b e^a and, b the relationship between DW (%WW) and energy density g⁻¹ wet weight (WW) including regression parameters of the linear regression lines y = ax + b. Regression parameters are depicted in the figures. Data were obtained from Tierney et al. (2002) (Macquarie Island), Van de Putte et al. (2010) (East Antarctica, February–March), Van de Putte et al. (2006) (Lazarev Sea, April), Van de Putte 2008 (Lazarev Sea, June/July) or collected during PS89 (Lazarev Sea, December). All measurements were done using bomb calorimetry. The legend, depicted in B, indicates month and location of data collection. No regression was fitted for the December-Lazarev Sea data in b, due to two individuals that had divergent dry weights
