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 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. [1 ...
The species is an important link in the diet of many amphibians. Adult beetles were easily eaten by the frog species Pelophylax nigromaculatus, but about 90% of swallowed beetles are excreted quickly. Surprisingly, the beetles survive. [10] [11] [12] Water beetles carry oxygen under their exoskeleton. The exoskeleton protects the beetle from ...

Diving beetles are the most diverse beetles in the aquatic environment and can be found in almost every kind of freshwater habitat, from small rock pools to big lakes. Some dytiscid species are also found in brackish water. [16] Diving beetles live in water bodies in various landscapes, including agricultural and urban landscapes.
Hydrophiloidea, known as water scavenger beetles, is a superfamily of beetles. Until recently it included only a single family, the Hydrophilidae (water scavenger beetles), but several of the subfamilies have been removed and raised to family rank. [1] Hydrophiliidae remains by far the largest member of the group, with nearly 3,000 described ...

[1] [2] [3] It is the most common and widespread species of Hydrophilus in North America, being found across the contiguous United States, southern Canada, and Mexico.
This family is known for aquatic beetles being 1–3 mm long, usually found crawling in vegetation near bodies of water despite not having the capability to swim so well. Their usual diet include algae, bacteria, protozoans and detritus found on stones and plants. [citation needed]
Stenocara gracilipes is a species of beetle that is native to the Namib Desert in southern Africa. This is one of the most arid areas of the world, receiving only 1.4 centimetres (0.55 in) of rain per year. The beetle is able to survive by collecting water on its bumpy back surface from early morning fogs.
