Semiaquatic

Examples of semiaquatic animals and plants are given below.

Semiaquatic animals

Semiaquatic 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.
  • Waterbirds, especially penguins, waterfowls, storks and shorebirds.
  • Some rodents such as beavers, muskrats and capybaras.
  • Some insectivorous mammals such as desmans, water shrews and platypuses.
  • Some carnivoran mammals, including seals, otters and polar bears.
  • Some marsupials, including the water opossum and the two lutrine opossums.
  • Hippos.
  • Indian rhinoceros.
  • Water buffalo.
  • Tapirs.
  • Moose.
• 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 non-aquatic life 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)
  • Amphibious centipedes, such as Scolopendra cataracta and relatives
• Semiaquatic annelids, such as the earthworm Sparganophilus or the Namanereidine bristleworms
• 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
