For vision in air, there is a general trend for fish to possess close-set, moveable, protruberant eyes set high on the head with various physical adaptations to the structure of the eye to allow for accurate vision in both air and water....
Adaptations of amphibious fish for surviving life out of water There are a small number of fish species, both marine and freshwater, that exhibit a truly amphibious habit that includes periods of aerial exposure. The d... MDJ Sayer - 《Fish & Fisheries》 被引量: 160发表: 2010年 The Africa...
Fishes that serve as prey for other fishes develop various defensive adaptations, such as spines on the fins (ruff, stickleback) or on the gill covers (ocean perch, Cottidae). Some fishes have poison glands at the base of their spines. Among the fishes that inhabit the waters of the USSR...
Adaptations of amphibious fish for surviving life out of water Habitat connectivity is vital to the persistence of migratory fishes. Native tropical island stream fish assemblages composed of diadromous species require... M Sayer 被引量: 0发表: 2005年 A fish eye out of water: epithelial surface...

so siliceous spicules and spongin should not be problematic (Pawlik2011). Yet, the morphological adaptations of fishes that allow for successful foraging upon sponges have rarely been considered beyond their initial species description (e.g., Hourigan et al.1989; Konow and Bellwood2011). Angelfi...
and/or adaptations to avoid resource limitation2. Indeed, fish typically do not have unlimited food resources in their natural environment107, and may need to balance demand and allocation with availability98,108. Larger individuals also have a higherper-capitaresource demand and may be less capable...
Thirst aroused in the forebrain by angiotensin II (AngII) or buccal drying motivates terrestrial vertebrates to search for water, whereas aquatic fish can drink surrounding water only by reflex swallowing generated in the hindbrain. Indeed, AngII induces drinking through the hindbrain even after removal...
together with specialized adaptations, must surely be in response to the widespread phenomenon of the biological light, which is produced by very many organisms in the deep sea, including those associated with the sea floor. In contrast to the pelagic oceanic fishes, relatively few deep-sea demers...
These fish have smaller eggs and a less developed state at hatching, presumably adaptations for passive downstream drift. Congeneric species that are completely fluvial in their life histories hatch as larger, precocious young that can hold position in stream flows. Such differences are observed among...
