Potamogalidae is the family of "otter shrews", a group of semiaquatic riverine afrotherian mammals indigenous to sub-Saharan Africa. [2] They are most closely related to the tenrecs of Madagascar, from which they are thought to have split about 47–53 million years ago.
Country codes; e.g., "Switzerland" can indicate the letters CH; ICAO spelling alphabet: where Mike signifies M and Romeo R; Conventional abbreviations for US cities and states: for example, "New York" can indicate NY and "California" CA or CAL. The abbreviation is not always a short form of the word used in the clue. For example:
In biology, being semi-aquatic refers to various macro organisms that live regularly in both aquatic and terrestrial environments. When referring to animals , the term describes those that actively spend part of their daily time in water (in which case they can also be called amphibious ), or land animals that have spent at least one life ...
The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia.
Some species of fish can "walk" along the sea floor but not on land. One such animal is the flying gurnard (it does not actually fly, and should not be confused with flying fish ). The batfishes of the family Ogcocephalidae (not to be confused with batfish of Ephippidae ) are also capable of walking along the sea floor.
Pressed closely but not fused, e.g. leaves against a stem. aquatic plant A plant whose natural habitat is water, living in or on water for all or a substantial part of its lifespan; generally restricted to fresh or inland waters. arachnoid Cobwebby, from being covered with fine white hairs. arborescent Tree-like in growth or general appearance ...
The legs are short, strong, and set far to the back of the body (more so in the more aquatic species), and have a leathery feel with a scaly texture. Combined with their body shape, this can make some species awkward on land, but they are stronger walkers than other marine and water birds such as grebes or petrels .
Green algae are also known to have extremely thin cell walls due to their aquatic surroundings, and research has shown that green algae is the closest ancestor to living terrestrial and aquatic plants. [34] Terrestrial plants have rigid cell walls meant for withstanding harsh weather, as well as keeping the plant upright as the plant resists ...
