Water Beetle
A water beetle is a generalized name for any beetle that is adapted to living in water at any point in its life cycle. Most water beetles can only live in fresh water, with a few Marine (ocean), marine species that live in the intertidal zone or littoral zone. There are approximately 2000 species of true water beetles native to lands throughout the world. Many water beetles carry an air bubble, called the elytra cavity, underneath their abdomens, which provides an air supply, and prevents water from getting into the Spiracle (arthropods), spiracles. Others have the surface of their exoskeleton modified to form a Gill#Plastrons, plastron, or "physical gill", which permits direct gas exchange with the water. Some families of water beetles have fringed hind legs adapted for swimming, but most do not. Most families of water beetles have larvae that are also aquatic; many have aquatic larvae and terrestrial adults. Diet Water beetles can be either herbivores, predators, or scavengers. ...

Noteridae
Noteridae is a family of adephagan water beetles closely related to the Dytiscidae, and formerly classified with them. They are mainly distinguished by the presence of a distinctive "noterid platform" underneath, in the form of a plate between the second and third pair of legs. The family consists of about 230 species in 14 genera, and is found worldwide, more commonly in the tropics. They are sometimes referred to as burrowing water beetles. These beetles are relatively small, ranging from 1 to 6 mm, with smooth oval bodies ranging from light brown to a darker reddish brown. The head is short and somewhat covered by the prothorax. Both adults and larvae are aquatic, and are commonly found around plants. They have a habit of burrowing through pond and marsh substrate, thus the common name, and are primarily carnivorous, with some scavenging observed. Genera Noteridae contains the following genera: * '' Canthydrus'' Sharp, 1882 * '' Hydrocanthus'' Say, 1823 * '' Mesonoteru ...

Ptilodactylidae
Ptilodactylidae is a family of beetles belonging to the Elateriformia. There around 500 extant species in 35 genera. They are generally associated with riparian and aquatic habitats. The larvae generally live associated with rotting wood or vegetation, or within gravel and detritus on the edge of water bodies. The larvae of some species feed on submerged rotting wood or on plant roots, while the adults of some species are known to feed on fungus with modified brush-like maxillae.Lawrence, John F..
