Toadfish is the common name for a variety of species from several different families of fish, usually because of their toad-like appearance. Dogfish is a name for certain species along the gulf coast.[ clarification needed ]


Dolphin-Toadfish relationship

Toadfish make up a notable portion of the dolphin's diet, approximately 13%. Scientific experiments have shown that the mating call of the toadfish alerts dolphin predators to the fish's location. Similarly, the sounds caused by the dolphin when hunting its prey alert toadfish to the location of the predators and cause the fish to silence their mating call. Male toadfish will reduce their mating calls by up to 50% when they hear the low sound of a dolphin's "pop". [1]


The entire family Batrachoididae are called toadfishes. They are benthic ambush predators, known for their ability to produce sound with their swim bladders.

<span class="mw-page-title-main">Bottlenose dolphin</span> Genus of dolphin

Bottlenose dolphins are aquatic mammals in the genus Tursiops. They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. Molecular studies show the genus definitively contains three species: the common bottlenose dolphin, the Indo-Pacific bottlenose dolphin, and Tamanend's bottlenose dolphin. Others, like the Burrunan dolphin, may be alternately considered their own species or be subspecies of T. aduncus. Bottlenose dolphins inhabit warm and temperate seas worldwide, being found everywhere except for the Arctic and Antarctic Circle regions. Their name derives from the Latin tursio (dolphin) and truncatus for their characteristic truncated teeth.

<span class="mw-page-title-main">Dusky dolphin</span> Species of mammal

The dusky dolphin is a dolphin found in coastal waters in the Southern Hemisphere. Its specific epithet is Latin for "dark" or "dim". It is very closely genetically related to the Pacific white-sided dolphin, but current scientific consensus holds they are distinct species. The dolphin's range is patchy, with major populations around South America, southwestern Africa, New Zealand, and various oceanic islands, with some sightings around southern Australia and Tasmania. The dusky dolphin prefers cool currents and inshore waters, but can also be found offshore. It feeds on a variety of fish and squid species and has flexible hunting tactics. The dusky dolphin is known for its remarkable acrobatics, having a number of aerial behaviours. The status of the dolphin is unknown, but it has been commonly caught in gill nets.

The silky shark, also known by numerous names such as blackspot shark, gray whaler shark, olive shark, ridgeback shark, sickle shark, sickle-shaped shark and sickle silk shark, is a species of requiem shark, in the family Carcharhinidae, named for the smooth texture of its skin. It is one of the most abundant sharks in the pelagic zone, and can be found around the world in tropical waters. Highly mobile and migratory, this shark is most often found over the edge of the continental shelf down to 50 m (164 ft). The silky shark has a slender, streamlined body and typically grows to a length of 2.5 m. It can be distinguished from other large requiem sharks by its relatively small first dorsal fin with a curving rear margin, its tiny second dorsal fin with a long free rear tip, and its long, sickle-shaped pectoral fins. It is a deep, metallic bronze-gray above and white below.

<span class="mw-page-title-main">Common bottlenose dolphin</span> Species of bottlenose dolphin

The common bottlenose dolphin or Atlantic bottlenose dolphin is a wide-ranging marine mammal of the family Delphinidae. The common bottlenose dolphin is a very familiar dolphin due to the wide exposure it gets in captivity in marine parks and dolphinariums, and in movies and television programs. It is the largest species of the beaked dolphins. It inhabits temperate and tropical oceans throughout the world, and is absent only from polar waters. While formerly known simply as the bottlenose dolphin, this term is now applied to the genus Tursiops as a whole. As considerable genetic variation has been described within this species, even between neighboring populations, many experts think additional species may be recognized.

The oyster toadfish, Opsanus tau, also known as the oyster toad, ugly toad, oyster cracker, oyster catcher, and bar dog, is a Northeast Atlantic species of fish of the family Batrachoididae. The maximum length of this toadfish is 43.2 cm (17 in), but they infrequently surpass 38 cm (15 in). The world record size for this species is 19.2 inches which is 48.76 cm. They are generally yellowish with a pattern of brown oblique bars. The species can live in poor conditions and needs little food to live. They can be found near the shore from Maine to Florida.

The red-tailed tropicbird is a seabird native to tropical parts of the Indian and Pacific Oceans. One of three closely related species of tropicbird (Phaethontidae), it was described by Pieter Boddaert in 1783. Superficially resembling a tern in appearance, it has almost all-white plumage with a black mask and a red bill. The sexes have similar plumage. As referenced in the common name, adults have red tail streamers that are about twice their body length. Four subspecies are recognised, but there is evidence of clinal variation in body size—with smaller birds in the north and larger in the south—and hence no grounds for subspecies.

<span class="mw-page-title-main">Colossal squid</span> Species of squid

The colossal squid is part of the family Cranchiidae. It is sometimes called the Antarctic squid or giant cranch squid and is believed to be the largest squid species in terms of mass. It is the only recognized member of the genus Mesonychoteuthis and is known from only a small number of specimens. The species is confirmed to reach a mass of at least 495 kilograms (1,091 lb), though the largest specimens—known only from beaks found in sperm whale stomachs—may perhaps weigh as much as 600–700 kilograms (1,300–1,500 lb), making it the largest known invertebrate. Maximum total length has been estimated at 9–10 metres (30–33 ft). The colossal squid has the largest eyes of any known creature ever to exist, with an estimated diameter of 27 cm (11 in).

The smooth toadfish is a species of fish in the pufferfish family Tetraodontidae. It is native to shallow coastal and estuarine waters of southeastern Australia, where it is widespread and abundant. French naturalist Christophe-Paulin de La Poix de Fréminville described the species in 1813, though early records confused it with its close relative, the common toadfish. The two are the only members of the genus Tetractenos after going through several taxonomic changes since discovery.

A bait ball, or baitball, occurs when small fish swarm in a tightly packed spherical formation about a common centre. It is a last-ditch defensive measure adopted by small schooling fish when they are threatened by predators. Small schooling fish are eaten by many types of predators, and for this reason they are called bait fish or forage fish.

<i>Batrachomoeus trispinosus</i> Species of fish

Batrachomoeus trispinosus, the three-spined frogfish or Broadbent's frogfish, is a species of Indo-Pacific toadfish, from the largely Old World subfamily, Halophryninae, of the family Batrachoididae. It is the type species of the genus Batrachomoeus. It is said to be the only fish known to cry like a baby and produce complex non-linear calls. Others fish can only make simple linear sounds but human babies and other mammals use non-linear sounds in their calls, in which other animals associate such non-linear sounds with a sense of emotional urgency.
