Some evidence indicates sound production in hardhead catfish is differentiated both mechanistically and contextually. At maturity, females develop flap-like fatty tissue by their pelvic finswhich results in them having larger pelvic fins than males. They also respond to chemical cues from injured sailfin molliesbut this response was weaker than that of the response from their own species.

If echolocation exists, it is likely only useful in the near field by the catfish. Like other members of the Ariidaehardhead catfish are paternal mouthbrooders.

The dorsal and pectoral fins each are supported by a sharp, slime-covered, barbed spine. Shrimp is a particularly effective bait to use. Hardhead catfish are edible, but like all catfish, require some effort gelis clean.

High vulnerability 56 of Phylogenetic diversity index Ref. The gafftopsail catfish looks similar to the hardhead catfish, but its dorsal spine has a distinctive fleshy extension like the fore-and-aft topsail of a ship. Commonly captured from catwalks, bridges and piers, particularly in passes and inland waterways.

The signal parameters have low frequency and amplitude, so far-field reverberations are unlikely to be useful. Several nonfunctioning eggs within the brood attach to the larger, viable eggs.

Many advantages to mouthbrooding exist as opposed to other forms of parental care, such as bubble nesting. These chemical responses had only been seen in freshwater ostariophysans.
