Grublings are a amphibious creature that inhabits both swamps and still ponds. They are primarily nocturnal and during the day they will hide in mud or under stones, logs, and vegetation.Grublings are omnivores, but they mostly consume small insects and other invertebrates.
 
Their diet can also include plants such as algae, diatoms and plankton. During the breeding season, grublings will migrate to shallow waters where they will lay their eggs.When threatened, grublings can quickly bury themselves in mud or vegetation.
 
They also have the ability to secrete a slimy mucous from the skin that helps them escape from predators.Grublings are an important part of aquatic ecosystems as they help maintain water quality and provide food for other species. They are also used as bait by anglers who are looking to catch larger fish.
