The dorsal spine is normally erect when the fish is excited and a tennis shoe or even a leather-soled shoe offers little protection. Collaborators Pictures Stamps, Coins Misc. Furthermore, hardhead catfish are the first indicator that Osteichthyes possibly could use directional hearing to detect obstacles. When fishing for this species in fresh water, assorted meats tend to work best as bait. Individuals within the group that produced sound avoided obstacles, whereas silent individuals crashed into obstacles frequently.

It is an opportunistic consumer that uses mud and sand flats as hunting grounds. As hardhead catfish grow longer, they increase in weight. The signal parameters have low frequency and amplitude, so far-field reverberations are unlikely to be useful. If echolocation exists, it is likely only useful in the near field by the catfish. Hardhead catfish are edible, but like all catfish, require some effort to clean.

Mouthbreeders are able to freely move with the eggs in their mouths, thus can move as necessary to protect both themselves and the broods. Another possibility is that males pick up eggs from depressions in the sand, as eggs tend to be demersal. Also, grinding of the pharyngeal teeth and rubbing of the pectoral spines against the pectoral girdle can produce sound.
