Walking Fish
A walking fish, or ambulatory fish, is a fish that is able to travel over ecoregion#Terrestrial, land for extended periods of time. Some other modes of non-standard fish locomotion include "walking" along the seabed, sea floor, for example, in handfish or frogfish. Types Most commonly, walking fish are amphibious fish. Able to spend longer times out of water, these fish may use a number of means of animal locomotion, locomotion, including springing, snake-like lateral undulation, and tripod-like walking. The mudskippers are probably the best land-adapted of contemporary fish and are able to spend days moving about out of water and can even climb mangroves, although to only modest heights. The climbing gourami is often specifically referred to as a "walking fish", although it does not actually "walk", but rather moves in a jerky way by supporting itself on the extended edges of its gill plates and pushing itself by its fins and tail. Some reports indicate that it can also climb t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Periophthalmus Gracilis
''Periophthalmus gracilis'', the slender mudskipper, known as belacak in Malay, is a species of mudskippers native to marine and brackish waters of the eastern Indian Ocean and the western Pacific Ocean where it is an inhabitant of the intertidal zone.

Walking Catfish
The walking catfish (''Clarias batrachus'') is a species of freshwater airbreathing catfish native to Southeast Asia. It is named for its ability to "walk" and wiggle across dry land, to find food or suitable environments. While it does not truly walk as most bipeds or quadrupeds do, it can use its pectoral fins to keep it upright as it makes a wiggling motion with snakelike movements to traverse land. This fish normally lives in slow-moving and often stagnant waters in ponds, swamps, streams, and rivers, as well as in flooded rice paddies, or temporary pools that may dry up. When this happens, its "walking" skill allows the fish to move to other aquatic environments. Considerable taxonomic confusion surrounds this species, and it has frequently been confused with other close relatives.Ng, Heok Hee, and Kottelat, Maurice (2008).

Devonian
The Devonian ( ) is a period (geology), geologic period and system (stratigraphy), system of the Paleozoic era (geology), era during the Phanerozoic eon (geology), eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago (Megaannum, Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of history of life#Colonization of land, life on land occurred during the Devonian, as free-spore, sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaf, leaves and true roots, and by the end of the period the first seed-bearing plants (Pteridospermatophyta, pteridospermatophyt ...

Tiktaalik NT Small
''Tiktaalik'' (; ) is a monospecific genus of extinct sarcopterygian (lobe-finned fish) from the Late Devonian Period, about 375 Mya (million years ago), having many features akin to those of tetrapods (four-legged animals). ''Tiktaalik'' is estimated to have had a total length of on the basis of various specimens. Unearthed in Arctic Canada, ''Tiktaalik'' is a non-tetrapod member of Osteichthyes (bony fish), complete with scales and gills—but it has a triangular, flattened head and unusual, cleaver-shaped fins. Its fins have thin ray bones for paddling like most fish, but they also have sturdy interior bones that would have allowed ''Tiktaalik'' to prop itself up in shallow water and use its limbs for support as most four-legged animals do. Those fins and other mixed characteristics mark ''Tiktaalik'' as a crucial transition fossil, a link in evolution from swimming fish to four-legged vertebrates. This and similar animals might be the common ancestors of all vertebrate terr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilled Lungfish
The gilled lungfish (''Protopterus amphibius''), also known as the East African lungfish, is a species of African lungfish. It is found in the swamps and flood plains of East Africa, and has been positively identified in Kenya, Somalia and Mozambique. Records from Tanzania require confirmation and may be the result of introductions. Description ''Protopterus amphibius'' generally only reaches a length of , making it the smallest extant lungfish.Primitive Fishes.com (Retrieved Feb. 19, 2010.) This lungfish is uniform blue or slate grey in colour. It has small or inconspicuous black spots and a pale grey belly. Like all African lungfish it has two lungs and is an obligate air-breather.

Bathypterois Grallator
The tripod fish or tripod spiderfish, ''Bathypterois grallator'', is a deep-sea benthic fish in the family Ipnopidae found at lower latitudes. It is now an iconic deep-sea fish, being observed and photographed by submersibles, using elongate fin rays of the tail and pelvic fins to stand on the ooze. ''B. grallator'' is hermaphroditic. Characteristics The tripodfish has long, bony rays that extend from the lower lobe of its tail fin and both pelvic fins. ''B. grallator'' is the largest member of its genus, commonly exceeding a standard length of and reaching total lengths of up to long. The tripodfish is often seen in its distinctive stance; standing on its three fin extensions (the namesake tripod) on the seabed, facing upstream with the antennae-like pectoral fin rays extended out, waiting for food. Even though the fins are presumably quite stiff to be able to support its weight, observations of swimming fish shows that their fins seem flexible; it is suggested that f ...

Ephippidae
Ephippidae is a family of percomorph fishes, the spadefishes, in the order Moroniformes. These fishes are found in the tropical and temperate oceans of the world, except for the central Pacific. Taxonomy Ephippidae was first proposed as a family in 1859 by the Dutch herpetologist and ichthyologist Pieter Bleeker. The 5th edition of the ''Fishes of the World'' classifies this family in the order Moroniformes with the Moronidae and Drepaneidae. Other authorities place this family alongside the Drepaneidae in the order Ephippiformes with the Moronidae classified as ''incertae sedis'' in the series Eupercaria. Other authorities classify all three families in the Moroniformes ''sensu'' ''Fishes of the World'' in the Acanthuriformes. Genera Ephippidae contains the following genera, 8 extant and 3 extinct ( means extinct): The extinct genus '' Exellia'' is classified within the Ephippidae by some authorities, other authorities place it in the family Exellidae.

Flying Fish
The Exocoetidae are a family (biology), family of Saltwater fish, marine Actinopterygii, ray-finned fish in the order (biology), order Beloniformes, known colloquially as flying fish or flying cod. About 64 species are grouped in seven genus, genera. While they do not "fly" in the same way a bird does, flying fish can make powerful leaps out of the water where their long wing-like fins enable gliding flight, gliding for considerable distances above the water's surface. The main reason for this behavior is thought to be to escape from underwater predators, which include swordfish, mackerel, tuna, and marlin, among others, though their periods of flight expose them to attack by avian predators such as frigate birds. Barbados is known as "the land of the flying fish" and the fish is one of the national symbols of the country. The Exocet missile is named after them, as variants are launched from underwater, and take a low trajectory, skimming the surface, before striking their target ...

Dactylopteridae
The flying gurnards are a family, Dactylopteridae, of marine fish notable for their greatly enlarged pectoral fins. As they cannot literally fly or glide in the air (like flying fish), an alternative name preferred by some authors is helmet gurnards. They have been regarded as the only family in the suborder Dactylopteroidei of the Scorpaeniformes. However, more recent molecular classifications put them in the order Syngnathiformes, in the superfamily Centriscoidea. They have been observed to "walk" along sandy sea floors while looking for crustaceans, other small invertebrates and small fish by using their pelvic fins. Like the true gurnards (sea robins), to which they may be related, they possess a swim bladder with two lobes and a "drumming muscle" that can beat against the swim bladder to produce sounds. They have heavy, protective scales and the undersides of their huge pectoral fins are brightly coloured, perhaps to startle predators. Most species are in the Indo-Pacific ...
