Figure 3. — (a) Visual sensing range scales with body size, L, as R ∼ L² in the clear-water limit () and as R ∼ constant in the turbid-water limit (). Parameters are C₀ = 0.3, C_th,min = 0.05 (adopted from [43]), K = 2.5 × 10⁻⁴ m², α = 0.04 m⁻¹ [47] (and α′ = 0.01 m⁻¹ for comparison). (b) Relationship of body size and resonance frequency based on equation (6.1) and using a swim bladder size r_b = L/10 for an individual at the surface (solid curve) and at 100 m depth (dashed curve). The dashed (grey) horizontal line indicates 1 kHz, below which most sounds generated by marine life are found.
