*2.3. Crude Protein*

Total nitrogen and protein contents of female and male jellyfish bells and oral arms are reported on a % dw basis by the bar graph in Figure 3. A nonstatistically significant interaction between the two independent variables (*p* > 0.05) was found (Table S3). Overall, investigated bells showed lower protein contents than oral arms (12.09–15.7% vs. 23.5–26.4%, *p* < 0.05), and nonstatistically significant differences were reported between female and male organisms (12.09–23.53% vs. 15.7–26.45%, *p* > 0.05).

**Figure 3.** Total nitrogen and protein contents of female and male jellyfish bells and oral arms. Data are reported on a % dw basis, as mean ± standard deviation (*n* = 3). Samples marked by different letters differ significantly (*p* < 0.05 by post hoc Tukey's HSD test).
