B. boddarti has fused pelvic fins, as in its fin rays are interconnected and merged with its skin, which aid in its walking across the mudflats it lives in. Its large pelvic ray fin bone structure provides B. boddarti with a sitting pad for stability in semi-terrestrial substrate and cushion for landing after hopping. The pelvic fins can also flatten into a slightly concave shape when it makes impact to further cushion its landing. Similarly to other mudskippers, B. boddarti has moist skin with capillaries near the surface in dermal bulges that allow it to perform cutaneous respiration, although it has been observed to have less mucous-secreting cells than more terrestrial species of mudskipper such as Periophthalmus variabilis, on account of it living primarily in aquatic areas and thus having greater access to moisture.
