Arothron multilineatus, the multilined pufferfish, is a species of ray-finned fish in the family Tetraodontidae. It is an uncommon fish and is known only from four specimens from Pagbilao in the Philippines, although photographs of individuals in the Ryukyu Islands, Mozambique and the Red Sea show that it has a wide distribution. It was first described by the Japanese ichthyologist Keiichi Matsuura in 2016. [1]

Description

The dorsal fin of A. multilineatus has ten to eleven soft rays and the anal fin has nine to eleven. The body is covered with small spinules except around the eyes and mouth, the gill openings, the fin bases and the sides of the caudal peduncle. This fish grows to a maximum length of 43 cm (17 in). [2] It is characterised by having narrow white convoluted linear markings on a deep greenish-brown background. It is similar in appearance to another rare species, Arothron carduus , which has narrow dark-coloured convoluted lines on a white background. [3]

Distribution and habitat

A. multilineatus is found at depths of between 10 and 25 m (30 and 80 ft) on sandy seabeds in the Ryukyu Islands. Underwater photographs from there, Mozambique and the Red Sea, and documentary evidence from the Philippines, indicate that it has a wide distribution. [4]

Controversy

Pufferfish in the genus Arothron are common in the shallow tropical waters of the Indo-Pacific region. These fish have been extensively photographed and studied, but this large distinctive fish was not described until 2016, the author basing his findings on four specimens from the Philippines and photographs of two specimens from the Red Sea. This raises the question of why such a sizeable fish had not been observed before; a certain minimum population size would have had to exist for the species to be viable. [5]

An alternative hypothesis is that this might not be a valid species at all, but might be an unusually patterned hybrid, perhaps a cross between A. hispidus and A. stellatus . [3] The description was made on the basis of the markings alone, and the confusion will be resolved when a taxonomic revision is done on this genus, including a genetic study. [5]

Tetraodontidae 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, blowies, bubblefish, globefish, swellfish, toadfish, toadies, 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.

Pufferfish mating ritual Animal mating behavior

The white-spotted pufferfish is known for its unique and complex courtship display which involves creating large, geometric circles in the sand. These circles are constructed in an effort to attract females for copulation. Males must maintain their circles in order to attract a mate. A female will evaluate the structure and choose to mate with the males after evaluation and completion of other mating behaviors.

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

Takifugu obscurus or the obscure pufferfish is a species of euryhaline, anadromous pufferfish first described by T. Abe in 1949. It has been categorized by the IUCN as a least-concern species globally since 2014; in South Korea, it is however classified as an endangered species due to overfishing of its endemic populations. The Catalogue of Life lists no subspecies of Takifugu obscurus. The species prefers deeper, clearer areas of brackish and fresh water, and is found estuaries, as well as rivers and tributaries thereof such as the South Korean rivers Geum, Han, and Imjin, or the Tamsui River in mainland China. 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.

Canthigaster aziz, known as Aziz's toby, is a species of pufferfish in the family Tetraodontidae. It was described in 2020 by Keiichi Matsuura, Sergey V. Bogorodsky, Ahmad O. Mal, and Tilman J. Alpermann based on a single specimen collected from the northern Red Sea off of Saudi Arabia. It was trawled from a depth of 315 m, which is reportedly the second highest depth at which any fish of the genus Canthigaster has been collected. The only known specimen measures 2 cm SL. The species was named after the King Abdulaziz University. It is thought to have been collected over a hard substrate as the trawling gear used to collect it was severely damaged during operation.
