Takifugu obscurus [7] or the obscure pufferfish is a species of euryhaline, [8] anadromous pufferfish first described by T. Abe in 1949. [2] [3] It has been categorized by the IUCN as a least-concern species globally since 2014; [9] in South Korea, it is however classified as an endangered species due to overfishing of its endemic populations. [10] The Catalogue of Life lists no subspecies of Takifugu obscurus. [6] The species prefers deeper, clearer areas of brackish and fresh water, [2] and is found in estuaries, as well as rivers and tributaries thereof such as the South Korean rivers Geum, Han, and Imjin, [10] or the Tamsui River in mainland China. [2] The species is endemic to North and South Korea, the Sea of Japan, and the East and South China Seas. Uses of Takifugu obscurus include human consumption, use in animal testing, and owning specimens as pets. As with most species of pufferfish, several organs of Takifugu obscurus contain tetrodotoxin, making it potentially poisonous if not prepared safely by trained persons.

Takifugu obscurus is characterized by the following traits: [5]

<span class="mw-page-title-main">Tetraodontidae</span> Family of pufferfish

Tetraodontidae is a family of primarily marine and estuarine fish of the order Tetraodontiformes. The family includes many familiar species variously called pufferfish, puffers, balloonfish, blowfish, blowers, blowies, bubblefish, globefish, swellfish, toadfish, toadies, toadle, honey toads, sugar toads, and sea squab. They are morphologically similar to the closely related porcupinefish, which have large external spines. The scientific name refers to the four large teeth, fused into an upper and lower plate, which are used for crushing the hard shells of crustaceans and mollusks, their natural prey.

<span class="mw-page-title-main">Fugu</span> Various species of pufferfish

The fugu in Japanese, bogeo or bok (복) in Korean, and hétún in Standard Modern Chinese is a pufferfish, normally of the genus Takifugu, Lagocephalus, or Sphoeroides, or a porcupinefish of the genus Diodon, or a dish prepared from these fish.

<i>Takifugu</i> Genus of fishes

Takifugu is a genus of pufferfish, often better known by the Japanese name fugu. There are 25 species belonging to the genus Takifugu and most of these are native to salt and brackish waters of the northwest Pacific, but a few species are found in freshwater of Asia or more widely in the Indo-Pacific region. Their diet consists mostly of algae, molluscs, invertebrates and sometimes crustaceans. The fish defend themselves by inflating their bodies to several times normal size and by poisoning their predators. These defenses allow the fish to actively explore their environment without much fear of being attacked.

<i>Arothron</i> Genus of fishes

Arothron is a genus in the pufferfish family Tetraodontidae found in warm parts of the Atlantic, Indian and Pacific Ocean. These species are sometimes kept in aquaria. The largest species is A. stellatus, which can reach 1.2 m (3.9 ft) in length.

<span class="mw-page-title-main">Map puffer</span> Species of fish

The map puffer, also known as the map pufferfish, scribbled pufferfish, or Kesho-fugu, is a demersal marine fish belonging to the family Tetraodontidae. The map puffer is typically found in tropical and subtropical waters from the Indian Ocean to the western Pacific Ocean. This fish contains tetrodotoxin, a potent and deadly chemical compound used to ward off predators. Despite being highly poisonous, the map puffer can be found both in the aquarium trade and certain food markets.

<i>Takifugu rubripes</i>

Takifugu rubripes, commonly known as the Japanese puffer, Tiger puffer, or torafugu, is a pufferfish in the genus Takifugu. It is distinguished by a very small genome that has been fully sequenced because of its use as a model species and is in widespread use as a reference in genomics.

<span class="mw-page-title-main">Grass puffer</span> Species of fish

The grass puffer, or Kusa-fugu, is a species of fish in the pufferfish family (Tetraodontidae). This common to abundant species is found in the northwest Pacific Ocean in China, Japan, Korea, the Philippines and Vietnam. It is primarily found in coastal waters, ranging to depths of 20 m (66 ft), but is often seen in brackish water and has also been recorded briefly entering freshwater. The grass puffer reaches up to 15 cm (6 in) in length.

<i>Reicheltia halsteadi</i> Species of fish

Reicheltia halsteadi, Halstead's toadfish, is a species of pufferfish endemic to Australia. This species grows to a length of 16 centimetres (6.3 in) TL. This species is the only known member of its genus.

<i>Arothron stellatus</i> Species of fish

Arothron stellatus, also known as the stellate puffer, starry puffer, starry pufferfish, or starry toadfish, is a demersal marine fish belonging to the family Tetraodontidae. It is found in shallow water in the Indo-Pacific region.

Takifugu chinensis, the Chinese puffer, is a species of fish in the family Tetraodontidae (pufferfish) that is found in coastal waters of China, Japan and Korea. This critically endangered pufferfish has drastically declined because of overfishing and habitat loss, but it is possibly also threatened by the widespread release/escape of aquacultured Takifugu rubripes within its range. These two species are similar, very closely related and perhaps should be considered conspecific, but they do differ in the colour of their anal fins.

<i>Arothron reticularis</i> Species of fish

Arothron reticularis, variously known as the reticulated pufferfish, reticulated blowfish or reticulated toadfish, is a ray-finned fish in the family Tetraodontidae. It is native to the tropical and sub-tropical Indo-Pacific region where its habitats include sandy and muddy seabeds, coral reefs, estuaries and mangrove areas.

<i>Takifugu poecilonotus</i> Species of fish

It contains tetrodotoxin like other members of the genus Takifugu. This species is found in fresh, brackish and saltwater environments.

Chelonodontops laticeps, also known as the bluespotted blaasop, is a species of pufferfish in the family Tetraodontidae.
