This fish seems to use its bizarre skull like a drum

The rockhead poacher fish is suggested to use its unique skull structure for communication, potentially drumming on it to convey messages. This anatomical feature may facilitate sound production, challenging the conventional emphasis on visual or chemical signals in fish communication. The exploration of the rockhead poacher's drumming behavior contributes to a broader understanding of underwater communication, indicating a complexity that may influence future studies in marine biology. The topic has shown enduring interest, surviving for nine days with a score of 31.
