weatherfish

Weatherfish are a group of elongated, eel-like freshwater fish belonging to the order Synbranchiformes. These fish are found in tropical and subtropical regions of Africa, Asia, and Australia. Their common name, "weatherfish," is derived from a belief that their increased activity and tendency to leave the water before heavy rains are indicative of impending weather changes. This behavior is likely a response to decreasing atmospheric pressure and oxygen levels in the water, which can occur before storms.

Physically, weatherfish are characterized by their long, slender bodies, often with small or absent pectoral and pelvic fins. They possess a continuous dorsal and anal fin that runs along most of their body, aiding in their sinuous locomotion. Their coloration varies depending on the species, but often includes shades of brown, grey, or olive green, providing camouflage in their muddy or vegetated habitats. They are primarily benthic, meaning they live on or near the bottom of rivers, lakes, and swamps.

Weatherfish are carnivorous, feeding on small invertebrates, insects, and sometimes other small fish. They are known for their ability to breathe air, possessing a modified swim bladder or gill chamber that allows them to extract oxygen from the atmosphere. This adaptation is crucial for survival in oxygen-poor waters and allows them to travel short distances over land, especially during periods of drought or when seeking new water bodies. This terrestrial movement further contributes to their "weatherfish" moniker, as they might be seen on the move before rain.
