Gulf Toadfish
Opsanus beta
The Gulf Toadfish is a broad-headed bottom fish with mottled camouflage, a powerful voice, and painful dorsal and pectoral spines.
Gulf Toadfish hide beneath rocks, docks, oyster structure, seagrass edges, and debris in bays and coastal water. Their mottled color blends with the bottom while they wait for prey.
Males produce a loud boat-whistle call to attract females. The sound comes from rapid contractions of muscles around the swim bladder and often surprises people near docks and seawalls.
