Remarks | Observations support the idea that this fish drifts and executes a sudden, deliberate bite within a short distance using its powerful jaws when prey moves within reach. Based on stomach contents, it is deduced that this fish feeds at least in part on the ocean floor. The headstanding, drift feeding orientation may offer supportive evidence for an electroreceptive function of the rostral organ (Ref. 28021). |
