Colombian Dwarf Numbfish

<em>Diplobatis colombiensis</em>, commonly known as the Colombian Dwarf Numbfish, is a cartilaginous fish species belonging to the genus <em>Diplobatis</em> within the family Narcinidae, a group of electric rays capable of generating electric discharges used for defense and prey stunning. This species is classified as Vulnerable, indicating a significant concern for its long-term population viability under current conditions. Specific habitat descriptions are not detailed in current records; however, narcinid electric rays are typically associated with soft-bottom marine habitats such as sandy or muddy seafloors in coastal and shelf waters of the western Atlantic and eastern Pacific. Specific country-level distributional records are not detailed in current documentation. The electric discharge mechanism of rays in this family is well-documented as a strategy for subduing prey and deterring predators. Dietary information specific to this species has not been recorded. Biological traits of this species remain poorly documented in the scientific literature. Threats to Vulnerable marine species such as <em>Diplobatis colombiensis</em> typically include bycatch in coastal fisheries and habitat degradation.
