Tenuidens

Tenuidens is a genus of ray-finned fish belonging to the family Gobiidae. The name "Tenuidens" is derived from Latin words, with "tenui" meaning slender and "dens" meaning tooth, likely referring to the fine, slender teeth of these fish. These gobies are characterized by their elongated bodies and typically small size, making them somewhat inconspicuous inhabitants of their marine environments.

Species within the Tenuidens genus are generally found in tropical and subtropical waters, often associated with coral reefs, seagrass beds, and sandy or muddy bottoms. Their specific habitat preferences can vary depending on the species. Like most gobies, they are benthic, meaning they live on or near the seafloor. Their diet usually consists of small invertebrates such as crustaceans and mollusks, which they forage for in their immediate surroundings.

Reproduction in Tenuidens follows typical goby patterns. Males often establish and defend territories, sometimes creating nests in suitable locations. Females deposit eggs, which are then guarded and fanned by the male until hatching. The exact number of recognized species within the genus can fluctuate as taxonomic research progresses and new species are described or existing ones reclassified. While not typically targeted by commercial fisheries, Tenuidens plays a role in the reef ecosystem as both predator and prey for larger marine animals.
