Mudskippers are any of the 23 extant species of amphibious fish from the subfamily Oxudercinae of the goby family Oxudercidae. [2] They are known for their unusual body shapes, preferences for semiaquatic habitats, limited terrestrial locomotion and jumping, and the ability to survive prolonged periods of time both in and out of water.
Mudskippers are found in mangrove swamps in Africa and the Indo-Pacific; they frequently come onto land, and can survive in air for up to 3-1/2 days. [5] Mudskippers breathe through their skin and through the lining of the mouth (the mucosa) and throat (the pharynx). This requires the mudskipper to be wet, limiting them to humid habitats.
The Atlantic mudskipper is a member of the genus Periophthalmus, which includes oxudercine gobies that have one row of canine-like teeth. The Atlantic mudskipper can grow up to 16 cm (6.3 in) in body length. Similar to other members of the genus, it has dorsally positioned eyes and pectoral fins that aid in locomotion on land and in water.
The eggs have an average diameter of 1 millimetre (0.039 in). The eggs are generally surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Some fish have thick, leathery coats, especially if they must withstand physical force or desiccation. These type of eggs can also be very small and ...
Boleophthalmus pectinirostris, commonly known as the great blue spotted mudskipper, is a species of mudskipper native to the north-western Pacific Ocean. It can be found on the coastlines of Japan , eastern China , Sumatra , Malaysia , Taiwan and the Korean Peninsula .
In an inverted Pikaia, the external gills that formerly pointed down were now angled upward, as are external gills in modern mudskippers and axolotls.. Flipping Pikaia also changed the orientation ...
Periophthalmus gracilis, a species of mudskipper, perched on land. Mudskippers are one type of walking fish. A walking fish, or ambulatory fish, is a fish that is able to travel over land for extended periods of time. Some other modes of non-standard fish locomotion include "walking" along the sea floor, for example, in handfish or frogfish.
Similarly to other mudskippers, B. boddarti has moist skin with capillaries near the surface in dermal bulges that allow it to perform cutaneous respiration, although it has been observed to have less mucus-secreting cells than more terrestrial species of mudskipper such as Periophthalmus variabilis, on account of it living primarily in aquatic ...
