Juvenile lungfish feed on insect larvae and snails, while adults are omnivorous, adding algae and shrimp to their diets, crushing them with their heavily mineralized tooth-plates. The fish's usual habitats disappear during the dry season, so they burrow into the mud and make a chamber about 30–50 cm (12–20 in) down, leaving a few holes to ...
Lungfish are omnivorous, feeding on fish, insects, crustaceans, worms, mollusks, amphibians and plant matter. They have an intestinal spiral valve rather than a true stomach. [9] African and South American lungfish are capable of surviving seasonal drying out of their habitats by burrowing into mud and estivating throughout the
The South American lungfish reaches up to about 4 feet (1.25 meters) long. While other fish rely upon gills to breathe, lungfish also possess a pair of lung-like organs.
All members of the order are obligatory air-breathers; only the Australian lungfish has functioning gills when adult; members of the Lepidosirenidae have gills only when they are larvae. [5] The South American and African lungfish also all have generally small scales and two lungs as opposed to the Australian lungfish's single lung. [5]

The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
