Aquatic insects live mostly in freshwater habitats, and there are very few marine insect species. [9] The only true examples of pelagic insects are the sea skaters , which belongs to the order Hemiptera, and there are a few types of insects that live in the intertidal zone , including larvae of caddisflies from the family Chathamiidae , [ 10 ...
Nepidae is a family of exclusively aquatic Heteropteran insects in the order Hemiptera. [1] They are commonly called water scorpions for their superficial resemblance to scorpions, due to their raptorial forelegs and the presence of a long slender process at the posterior end of the abdomen, resembling a tail.

Ascidiacea, commonly known as the ascidians or sea squirts, is a paraphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders. [2] Ascidians are characterized by a tough outer test or "tunic" made of the polysaccharide cellulose. Ascidians are found all over the world, usually in shallow water with salinities over ...
Trilobites were arthropods, like modern insects, spiders, millipedes and crustaceans, and they evolved into a wide range of shapes and sizes before going extinct around 252 million years ago.
Nicknamed “dinosaur shrimp”, Triops are relatives of the oldest living creatures, Triops cancriformis, have two main eyes and a pit organ “third eye” that enables insects to detect changes ...
Although Bathynomus have been recorded in water as warm as 20 °C (68 °F), they are primarily found in much colder places. [15] For example, during a survey of the deep-sea fauna of Exuma Sound in the Bahamas, B. giganteus was found to be common in water between 3.25 and 13 °C (37.8 and 55.4 °F), but more abundant towards the lower temperature.
Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera).
Nepomorpha is an infraorder of insects in the "true bug" order . They belong to the "typical" bugs of the suborder Heteroptera. Due to their aquatic habits, these animals are known as true water bugs. They occur all over the world outside the polar regions, with about 2,000 species altogether.
