Are mudskippers amphibious fish?
Mudskippers are amphibious fish. They are of the family Oxudercidae [2] and the subfamily Oxudercinae. There are 32 living species of mudskipper. They are known for their unusual appearance and their ability to survive both in and out of water.
Is the mudskipper a transitional animal?
A major problem for evolution is that the first mudskipper in the fossil record is morphologically a modern mudskipper. Long assumed to be a transitional animal between a swimming fish and a tetrapod (four footed) animal, a recent study by Kutschera and Elliott (2013, p.
How do mudskippers adapt to their environment?
Mudskippers typically live in burrows in intertidal habitats, and exhibit unique adaptations to this environment that are not found in most intertidal fishes, which typically survive the retreat of the tide by hiding under wet seaweed or in tide pools. [6] These burrows are most often characterised by their smooth and vaulted ceilings.
What do mudskippers eat?
The different species have adapted to various diets on the mudflats. Boleophthalmus boddarti is detritivorous, while others will eat small crabs, insects, snails and even other mudskippers. [11]

What type of animal is a mudskipper?
mudskipper, any of about six species of small tropical gobies of the family Gobiidae (order Perciformes). Mudskippers are found in the Indo-Pacific, from Africa to Polynesia and Australia. They live in swamps and estuaries and on mud flats and are noted for their ability to climb, walk, and skip about out of water.
Are there amphibian fish?
Amphibious fish are fish that are able to leave water for extended periods of time. About 11 distantly related genera of fish are considered amphibious. This suggests that many fish genera independently evolved amphibious traits, a process known as convergent evolution.
What group does a mudskipper belong to?
Family GobiidaeMudskippers belong to the Family Gobiidae and include these four genera Boleophthalmus, Periophthalmus, Periophthalmadon and Scartelaos. Features: Those seen about 6-12cm, some species can be much larger or smaller.
Why is a mudskipper not an amphibian?
Although mudskippers are fish, they are more comfortable crawling around on the mud than being submerged in water. This is because they are amphibious, and can live out of water for extended periods of time. They breathe by retaining water in enlarged gill chambers, and can also breathe through their wet skin.
Is a Mudfish an amphibian?
Answer and Explanation: The mudfish is not an amphibian is it a very adaptable fish. Mudfish belong to the Family Galaxiidae and the Genus Neochanna.
Which is not an amphibian?

What are mudskippers related to?
Mudskippers: amphibious fishes that climb trees. Closely related to the blennies are fishes in the family Gobiidae. This is the largest family of marine fishes with about 200 genera and 1,500 species.
Are mudskippers tetrapods?
Mudskippers flop around on their pectoral fins on intertidal tropical mudflats, a crossover realm between water and land. They didn't exist in their present form 350-400 million years ago, so they cannot be the ancestors of tetrapods.
Are mudskippers freshwater or saltwater?
Mudskippers are brackish fish. Brackish water occurs in estuaries, which are dynamic environments with the specific gravity (salt content) affected by tides, evaporation, rainfall and drainage from rivers and streams.
Overview
Adaptations
Compared with fully aquatic gobies, these specialised fish present a range of peculiar anatomical and ethological adaptations that allow them to move effectively on land as well as in the water. As their name implies, these fish use their fins to move around in a series of skips.
Although mudskippers' fins do not have a joint homologous to the elbow, the j…
Taxonomy
Oxudercinae is sometimes classified within the family Gobiidae (gobies). Recent molecular studies do not support this classification, as oxudercine gobies appear to be paraphyletic relative to amblyopine gobies (Gobiidae: Amblyopinae), thus being included in a distinct "Periophthalmus lineage", together with amblyopines. Mudskippers can be defined as oxudercine gobies that are "fully terrestrial for some portion of the daily cycle" (character 24 in Murdy, 1989 ). This would de…
Behaviour
Mudskippers typically live in burrows in intertidal habitats, and exhibit unique adaptations to this environment that are not found in most intertidal fishes, which typically survive the retreat of the tide by hiding under wet seaweed or in tide pools. These burrows are most often characterised by their smooth and vaulted ceilings. The way the males dig these burrows has been found to be directly linked to their ability to survive submerged in almost anoxic water. It has also been foun…
Species
The genus Periophthalmus is by far the most diverse and widespread genus of mudskipper. Eighteen species have been described. Periophthalmus argentilineatus is one of the most widespread and well-known species. It can be found in mangrove ecosystems and mudflats of East Africa and Madagascar east through the Sundarbans of Bengal, Southeast Asia to Northern Australia, southeast
