Semiaquatic

In biology, semiaquatic can refer to various types of animals that spend part of their time in water, or plants that naturally grow partially submerged in water. Examples are given below.

Semiaquatic animals

Semi aquatic animals include:
* Vertebrates
** Amphibious fish; also several types of normally fully aquatic fish such as the grunion and plainfin midshipman that spawn in the intertidal zone
** Some amphibians such as newts and salamanders, and some frogs such as fire-bellied toads and wood frogs.
** Some reptiles such as crocodilians, turtles, water snakes and marine iguanas.
** Penguins.
** Some rodents such as beavers, muskrats and capybaras.
**Some insectivorous mammals such as desmans, water shrews and platypuses.
** Some carnivoran mammals, including seals, polar bears and otters.
** Hippopotamuses.
* Semiterrestrial echinoderms of the intertidal zone, such as the "cliff-clinging" sea urchin '' Colobocentrotus atratus'' and the starfish '' Pisaster ochraceus''
*Arthropods
** Aquatic insects (e.g., dragonflies) with at least one nonaquatic life-cycle stage (e.g., adults), or amphibious insects (e.g., amphibious caterpillars or the ant ''Polyrhachis sokolova''). Members of the hemipteran infraorders Gerromorpha and Nepomorpha occupy a variety of semiaquatic and aquatic niches, with many of the former locomoting on the water surface; a few of these are marine (e.g., ''Halobates'', '' Hermatobates'').
** Semiaquatic springtails, such as ''Anurida maritima''
** Semiterrestrial malacostracan crustaceans (e.g., many crabs, such as '' Pachygrapsus marmoratus'', some amphipods, such as '' Orchestia gammarellus'', some isopods, such as ''Ligia oceanica'' and some barnacles, such as '' Balanus glandula'')
** Horseshoe crabs are mostly aquatic but spawn in the intertidal zone; juveniles live in tidal flats
** Semiaquatic spiders, such as '' Ancylometes'' or '' Dolomedes'' (these are distinct from the almost fully aquatic '' Argyroneta'')
** An amphibious centipede, '' Scolopendra cataracta''
* Semiaquatic annelids, such as the earthworm '' Sparganophilus''
* Molluscs
** Intertidal bivalves, such as '' Enigmonia'', which lives on mangroves
** Intertidal chitons, such as '' Acanthopleura granulata''
** Semiterrestrial gastropods, such as the intertidal ''Patella vulgata'', a limpet; also amphibious freshwater and marine snails, such as '' Pomatiopsis'' or '' Cerithideopsis scalariformis'', respectively
* Semiterrestrial flatworms of the intertidal zone, such as the acotylean '' Myoramyxa pardalota''

Semiaquatic plants

Semi aquatic plants include:
* Semiaquatic angiosperms (e.g., mangroves, water spinach, water cabbage, and the entire order Nymphaeales)
* Semiaquatic conifers, such as pond cypress
* Semi aquatic ferns, such as ''Pilularia americana''
* A semiaquatic horsetail, ''Equisetum fluviatile''
* Semiaquatic quillworts, such as ''Isoetes melanospora''
* Semiaquatic club mosses, such as ''Lycopodiella inundata''
* Semiaquatic mosses, such as '' Sphagnum macrophyllum''
* Semiaquatic liverworts, such as '' Riccia fluitans''
