Few vertebrates capture prey in both the aquatic and the terrestrial environment due to the conflicting biophysical demands of feeding in water versus air. The Atlantic mudskipper (Periophthalmus barbarus) is known to be proficient at feeding in the terrestrial environment and feeds predominately in this environment. Given the considerable forward flow of water observed during the mouth-opening...

After the discovery of aerial embryonic incubation in mudskippers, it was found that male induces larval hatching by removing air from egg-chamber so eggs immerse water. Do adults provide additional support to newly hatched larvae help them leave life-endangering hypoxic water inside burrow? This paper compares 18 events 3 species: dusky gilled mudskipper, Pearse´s mudskipper and slender mudski...

Escape responses in fishes are rapid behaviors that are critical for survival. The barred mudskipper (Periophthalmus argentilineatus) is an amphibious fish that must avoid predators in two environments. We compared mudskipper terrestrial and aquatic escapes to address two questions. First, how does an amphibious fish perform an escape response in a terrestrial environment? Second, how similar i...

Intertidal mudflats are highly productive ecosystems that impose severe environmental challenges on their occupants due to tidal oscillations and extreme shifts in habitat conditions. Reproduction on mudflats requires protection of developing eggs from thermal and salinity extremes, O(2) shortage, dislodgement by currents, siltation and predation. Mudskippers are air-breathing, amphibious fishe...

Hypoxia-inducible factor-1α (HIF-1α) plays a critical role in immune and inflammatory responses and is important in controlling a variety of processes in monocytes and macrophages. However, very little information is available about the functions of HIF-1α in fish monocytes/macrophages (MO/MФ). In this study, the cDNA sequence of the mudskipper (Boleophthalmus pectinirostris) HIF-1α gene (BpHIF...

Coupled behavioural observations and acoustical recordings of aggressive dyadic contests showed that the mudskipper Periophthalmodon septemradiatus communicates acoustically while out of water. An analysis of intraspecific variability showed that specific acoustic components may act as tags for individual recognition, further supporting the sounds' communicative value. A correlative analysis am...

Ochlerotatus baisasi was observed and photographed feeding on a mudskipper (Periophthalmus argentilineatus). Origin of blood meals in the stomachs of female mosquitoes collected at burrows of land crabs and mud lobsters in the mangrove forests of Oura, Okinawa, and Komi, Iriomote (the Ryukyu Islands), was determined by enzyme-linked immunosorbent assay to be from a fish source.

Mangrove forest is one of the ecosystems in coastal area that plays an important role as a habitat for iktiofauna, which gelodok fish community. The purpose this study was to compare community structure mudskippers at Bahak Indah Coast, Tongas, Probolinggo with or without mangrove vegetation. conducted January–February 2022. determination observation station carried out purposively, determined ...

Lake Siombak is a tidal lake that an estuary around the covered with various mangrove trees. It interesting to study fish's spatial and temporal distribution as unique distinctive ecosystem. This research was conducted for year (from September 2018 August 2019). Fish sampling performed by installing gill nets (mesh size 1 inch) cast 0.5 inch). Gill were installed at high low tides during full m...

The neurohypophysial hormones, arginine vasotocin and isotocin, regulate both hydromineral balance and social behaviors in fish. In the amphibious mudskipper, Periophthalmus modestus, we previously found arginine-vasotocin-specific regulation of aggressive behavior, including migration of the submissive subordinate into water. This migration also implies the need for adaptation to dehydration. ...
