Thymichthys is a genus in the handfish family Brachionichthyidae. Like other handfishes, they move by means of walking on their pectoral fins, which resemble hands.

Contents

Thymichthys is distinguished by its wart-like protuberances, strongly demarcated sensory scales, and dermal appendages. The coloring is a bright pattern of blotches, spots, and reticulations. [1]

The generic epithet is derived from the Greek thymos (warty excrescence) and ichthys (fish). [1]

Spotted handfish

The spotted handfish is a rare Australian fish in the handfish family Brachionichthyidae. It is classified as Critically Endangered on the IUCN Red List 2020. It is a benthic fish usually found at depths of 5 to 10 m, with overall sightings varying from a minimum of 2 to a maximum of 30 m deep. The spotted handfish is unusual in that it has highly adapted pectoral fins, which appear like hands and allow it to walk on the sea floor. It has a highly restricted range, being found only in the estuary of Derwent River, Tasmania, and nearby areas.

Frogfish

Frogfishes are any member of the anglerfish family Antennariidae, of the order Lophiiformes. Antennariids are known as anglerfish in Australia, where the term "frogfish" refers to members of the unrelated family Batrachoididae. Frogfishes are found in almost all tropical and subtropical oceans and seas around the world, the primary exception being the Mediterranean Sea.

Handfish Family of fishes

Handfish are any anglerfish within the family Brachionichthyidae, a group which comprises five genera and 14 extant species. These benthic marine fish are unusual in the way they propel themselves by walking on the sea floor rather than swimming.

<i>Brachionichthys</i>

Brachionichthys is the type genus of the handfish family Brachionichthyidae. Originally, all species of handfish were included in Brachionichthys, but researchers have since split species off into five additional genera.

Asymbolus is a genus of catshark in the family Scyliorhinidae.

Visayan warty pig

The Visayan warty pig is a critically endangered species in the pig genus (Sus). It is endemic to six of the Visayan Islands in the central Philippines. It is known by many names in the region with most translating into 'wild pig': baboy ihalas, baboy talonon, and baboy sulop

Philippine warty pig

The Philippine warty pig is one of four known species in the pig genus (Sus) endemic to the Philippines. The other three endemic species are the Visayan warty pig, Mindoro warty pig and the Palawan bearded pig, also being rare members of the family Suidae. Philippine warty pigs have two pairs of warts, with a tuft of hair extending outwards from the warts closest to the jaw. It has multiple native common names, but it is most widely known as baboy damo in Tagalog.

<i>Paramesotriton</i>

Paramesotriton, also known as warty newts or Asian warty newts, is a genus of salamanders in the family Salamandridae. The genus is found in southwestern and southern China and in northern Vietnam. Most of the species are endemic to China, and the majority of them have been described recently, since 2008. The genus includes both pond and stream dwellers.

Javan warty pig

The Javan warty pig, also called Javan pig, is an even-toed ungulate in the family Suidae. It is endemic to the Indonesian islands Java and Bawean, and is considered extinct on Madura. It is listed as Endangered on the IUCN Red List since 1996.

Oliver's warty pig or Mindoro warty pig is a small species in the pig genus (Sus) which can only be found on the island of Mindoro in the central Philippines. This species previously treated to be a subspecies of S. philippensis, was shown to be morphologically and genetically different.

The Philippines has four endemic species of wild pigs. This makes the Philippines unique in having arguably the largest number of endemic wild pigs. Two separate populations of unstudied wild pig species have been reported on the islands of Tawi-Tawi, and Tablas.

Figaro is a genus of catshark, and part of the family Scyliorhinidae. Until 2008, Figaro was generally considered to be a subgenus of Galeus. The two known species are found off Australia, inhabiting deep, offshore waters on or near the bottom. Figaro contains small, slender, firm-bodied sharks that bear distinctive crests of enlarged, spiny dermal denticles along the dorsal and ventral edges of their short caudal fins. The caudal peduncle is relatively long, such as that the anal and caudal fins are some distance apart. In adult males, the inner margins of the pelvic fins are fused together to form a subtle "apron" over the claspers. F. boardmani is a predator of fishes, crustaceans, and cephalopods, and is oviparous; less is known about the F. striatus. Both are harmless and are of no economic importance.

Brachiopsilus is a genus in the handfish family Brachionichthyidae.

Pezichthys is a genus in the handfish family Brachionichthyidae.

Red handfish

The red handfish is a species of handfish in the genus Thymichthys, found in Frederick Henry Bay, Tasmania.

Ziebell's handfish is a rare Australian handfish in the genus Brachiopsilus. It is known only from eastern and southern Tasmania. Ziebell's handfish may possibly be extinct, as there have been no confirmed sightings since 2007. Currently, however, the species is listed as critically endangered on the IUCN Red List.

The smooth handfish is an extinct species of handfish in the genus Sympterichthys. It was endemic to waters off the coast of Tasmania, mainly the D’Entrecasteaux Channel. It was declared extinct by the IUCN Red List in May 2018 and once again in March 2020, marking the first entirely marine fish classified as such.

The Moulton's handfish is an endangered species of handfish in the genus Sympterichthys. It is endemic to waters off the southeastern coast of Australia and possibly once New Zealand. It was first described as a distinct species in 2009 by Peter Last and Daniel Gledhill. It lives at a depth of around 105 metres (344 ft) - 150 metres (490 ft).
