Species are found predominantly in fast flowing, well oxygenated rivers, occasionally also in lakes.

The clean, well oxygenated, concrete-lined, fast flowing water provides the ideal environment for the barbel.

However, the type locality of L. stellatum is a stream, permanently flowing and well oxygenated.

Crayfish are also found in many rivers, especially those that are swift running and well oxygenated.

Most importantly, when she put them into a toxic gas chamber one night, the next morning, the air in the chamber was clear and well oxygenated.

The movement of his pectoral fins creates a current of water through the nest, bringing fresh (well oxygenated) water to the eggs.

The fast flow rate causes turbulence which keeps the water well oxygenated.

Habitat: Common in fast-flowing, well oxygenated fresh water and well-drained vegetated ponds.

Contrary to the above model, breathing is maintained in lizards during movement, even above their aerobic scope, and arterial blood remains well oxygenated.

The trace fossil assemblages in the formation suggest that it was below wave base and reasonably well oxygenated.
