Mudskipper fishes can maintain their metabolism while they are confined in mudflat burrows filled with oxygen-depleted water, and their eggs, deposited in the burrows, can develop under severely hypoxic conditions. How they cope with such conditions has been unclear. We report here that a mudskipper species Periophthalmodon schlosseri (Fig. 1) accumulates air in its burrows. This behaviour seems to be an adaptation to provide oxygen for burrow-dwelling fish and for embryos developing in the… Expand
Mudskippers brood their eggs in air but submerge them for hatching
TLDR
Japanese mudskipper Periophthalmus modestus has developed a reproductive strategy that allows it to nurture eggs in this severe habitat rather than migrating away from the mudflat, which requires that mudskippers eggs be specialized to develop in air and that the air-breathing capacity of the egg-guarding male be integrated in a complex behavioural repertoire.

Roles of environmental cues for embryonic incubation and hatching in mudskippers.
TLDR
Further comparative studies with both mudskippers and other oxudercine gobies dwelling mudflats could shed new light on how vertebrates solved problems of reproduction when they expanded habitats to environments in an air-water interface. Expand
Roles of air stored in burrows of the mudskipper Boleophthalmus pectinirostris for adult respiration and embryonic development.
TLDR
The deposited air appears to be a crucial source of oxygen for the embryos developing in the egg chamber of the burrow, but may play only a subsidiary role for adult respiration during presumed high-tide confinement. Expand
Burrow air phase maintenance and respiration by the mudskipper Scartelaos histophorus (Gobiidae: Oxudercinae)
TLDR
A laboratory burrow and mudflat system was used to examine aspects of burrow air-phase maintenance and utilization by the amphibious mudskipper Scartelaos histophorus, finding that over the course of `high-tide' confinement, burrow-water PO2 declines, making the air phase more important for respiration.

Intertidal burrows of the air-breathing eel goby, Odontamblyopus lacepedii (Gobiidae: Amblyopinae)
TLDR
Investigation of the intertidal burrows using resin casting demonstrated a highly branched burrow system, ostensibly of selective value for aerial predator avoidance during air breathing in O. lacepedii. Expand
Direct evidence for aerial egg deposition in the burrows of the Malaysian mudskipper, Periophthalmodon schlosseri
TLDR
The presence of mudskipper eggs in an air-filled chamber was confirmed by direct endoscopic observation of intact burrows of Periophthalmodon schlosseri in a mudflat in Penang, Malaysia by unequivocally demonstrated by the existence of an air–water interface inside the chambers. Expand
Ecology of the Australian mudskipper Periophthalmus minutus, an amphibious fish inhabiting a mudflat in the highest intertidal zone
A population of Periophthalmus minutus inhabiting a mudflat in the highest intertidal zone in Darwin was investigated for surface activity, feeding and reproduction in relation to environmentalExpand
First observations of the burrows of Anguilla japonica
TLDR
Observations indicate that anguillids are able to construct their own burrows in soft mud sediments that may be used for extended periods of time. Expand

Abstract Constructing burrows is energetically expensive, yet is a common trait across a broad spectrum of animals. The benefits of using burrows must therefore outweigh the costs of constructingExpand
Food and feeding ecology of the MUDSKIPPER Periopthalmus koelreuteri (PALLAS) Gobiidae at Rumuolumeni Creek, Niger Delta, Nigeria
TLDR
The food habits of the mudskipper Periophthalmus keolreuteri (Pallas) from the mudflats at Rumuolumeni Creek, Niger Delta, Nigeria were studied and results indicate that the juveniles were herbivorous feeding more on aquatic macrophytes, diatoms and algal filaments while the adults had a dietary shift towards crustaceans, aquatic and terrestrial insects and polychaetes.

TLDR
Physical principles governing the suitability of air and water as respiratory media, and the habitats of extant air-breathing fishes are reviewed, and terms and concepts related to aerial and aquatic gas exchange and bimodal respiration are defined. Expand
A taxonomic revision and cladistic analysis of the oxudercine gobies (Gobiidae : Oxudercinae)
TLDR
The Oxudercinae can be defined on the basis of derived states of certain neurocranial bones and muscles, eye position, nasal flap morphology, the palatine-ectopterygoid arrangement, reduction in size of the premaxillae ascending processes, and in having a single anal fin pterygiophore anterior to the first hemal spine.
