Structural Differences between Alligator Pipehorse and Bay Pipefish Tails

Abstract

This study compares the structure and mechanical properties of the bony plates from the tails of the Alligator pipehorse and the Bay pipefish. These bony plates provide the fish support and protection. The tail structures of both species were investigated by optical and scanning electron microscopy. Partial deproteinization of the samples revealed differences between the connections of the bony plates. The plates of the pipehorse overlap, allowing for flexibility of its tail. In contrast, the plates in the pipefish interlock, making the tail more difficult to bend. These mechanisms contribute to the prehensility and non-prehensility of the tails of the pipehorse and pipefish, respectively.
