Abstract
The white spotted pufferfish (Torquigener albomaculosus) constructs intricate sand nests for mating and hatching its eggs. These circular nests provide increased aeration and protection from shear stress for the eggs. The pufferfish selectively separates fine and rough sand, accumulating fine sand in the center of the circle. While comparisons with other fish species highlight the importance of appropriate spawning substrate, its specific relevance to the pufferfish remains unclear. Limited research has focused on female pufferfish and nest-building fitness. Further studies should explore sex-specific benefits and fitness implications. Comparisons with other species suggest potential benefits such as fitness signaling, male presence, and parental investment. The nest likely plays a role in mate selection for the pufferfish's unique reproductive behavior. The construction of these nests represents a courtship display by male pufferfish and deserves recognition for its complexity and significance.16
