  Toadfish - Wikipedia, the free encyclopedia
The toadfishes are a type of ray-finned fish normally found on the sand and mud bottoms of coastal waters worldwide, notable for somewhat broad heads and drab coloration reminiscent of terrestrial toads, as well as for the ability of some species to "sing" using their swim bladders.
Toadfishes are usually scaleless, with eyes set high on large heads.
Toadfishes of the genus Porichthys, the midshipman fishes, have photophores and four lateral lines, while the Thalassophryninae are venomous, with a total of four hollow spines (two dorsal and one on each opercle) connecting to venom glands and capable of delivering a painful wound.

 Toadfish STS-95
Because the toadfish's vestibular system is very similar to our own, the fish has become a well-known experimental model for learning more about balance disorders such as Meniere's disease and benign paroxysmal positional vertigo.
The toadfish is also a good model for studying motion sickness, including that experienced by astronauts during space flight.
The toadfish were fitted with a monitoring system that enabled Highstein to analyze changes to their vestibular system, specifically their otoliths, before, during, and after space flight.

The Gulf toadfish, Opsanus beta, is from temperate Atlantic waters and it belongs to a very different family, the Batrachoididae.
It is doubtful that the oyster toadfish are consuming many lobsters, particularly since you have observed the return of lobsters late in summer.
It is more likely that the toadfish are driving the lobsters into deeper water or adjacent non-rocky areas, or more simply that the lobsters stay well hidden during the period when toadfish are most abundant.

Opsanus tau, the oyster toadfish, also known as the oyster toad, or collectively as dowdies, is a small demersal predator that lives year-round in the Bay, mostly in inshore waters along the sandy or mud bottoms of rivers, among natural and man-made detritus.
The unlovely toadfish has large, protruding eyes; a broad mouth and fleshy areas (including flesh-like 'whiskers') surrounding the jaws; a short snout and scaleless, slimy skin; a rounded caudal fin and separate dorsal fins enveloping three short spines; yellowish brown skin with oblique brown bars extending on to the fins.
Toadfish fry never pass through a planktonic or drifting phase, which appears, along with their sluggishness, to limit their geographical range as adults.

Blessed with a face that only a mother could love, some males of a type of toadfish called the plainfin midshipman work hard for a date, hiding under rocks in shallow waters and humming to attract egg-laying females.
The toadfish, which can be found in the North Pacific from California all the way to Alaska, makes the humming sound by vibrating a set of sonic muscles on its air bladder 6,000 times a minute for more than an hour at a time, an amazing combination of speed and endurance.
Not everyone is enthused about toadfish tunes; during the summer mating season when the bottom-feeding toadfish move into shallow waters their nocturnal calls have been known to annoy houseboat owners.

Now scientists are studying the homely toadfish, known scientifically as Porichthys notatus, for clues to evolutionary biology and acoustics and even for insights into several rare muscular diseases.
Unlike humans and other animals whose muscles are long stretches of fiber, the toadfish has a music muscle in which the protein forms a hollow rod filled with a chemical called ATP that provides it with tremendous amounts of energy so it can keep vibrating against its swim bladder loudly and tirelessly, on and on.
The toadfish is constant prey for sharks, which makes it valuable as bait for shark fishermen and poses a scarcity problem for scientists.
