In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in living fish. The ...
Some of them resemble fish, some shrimp, some polychaetes, some tubeworms, and some simply a formless lump; one genus, Echinophryne, has no esca at all. Despite very specific mimicry in the esca, examinations of stomach contents do not reveal any specialized predation patterns, for example, only worm-eating fish consumed by frogfishes with worm ...
Fish physiology is the scientific study of how the component parts of fish function together in the living fish. [2] It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes. In practice, fish anatomy and physiology complement each other, the former dealing with the structure of a fish, its organs or ...
Batrachoididae / b æ t r ə ˈ k ɔɪ d ɪ d iː / is the only family in the ray-finned fish order Batrachoidiformes / b æ t r ə ˈ k ɔɪ d ɪ f ɔːr m iː z /.Members of this family are usually called toadfish or frogfish: both the English common name and scientific name refer to their toad-like appearance (batrakhos is Greek for frog).
The fish has long filaments along the middle of its head, which are, in fact, the detached and modified three first spines of the anterior dorsal fin. The filament most important to the angler is the first, which is the longest, terminates in a lappet, and is movable in every direction.
The Digital Fish Library (DFL) is a University of California, San Diego project funded by the Biological Infrastructure Initiative (DBI) of the National Science Foundation (NSF). The DFL creates 2D and 3D visualizations of the internal and external anatomy of fish obtained with magnetic resonance imaging (MRI) methods and makes these publicly ...
In fish, fertilisation of eggs can be either external or internal. In many species of fish, fins have been modified to allow internal fertilisation. Similarly, development of the embryo can be external or internal, although some species show a change between the two at various stages of embryo development.
The pectoral fins are angled and help, with the pelvic fins, to move the fish on the bottom and to keep a stable position for ambush. The warty frogfish exhibits biofluorescence, that is, when illuminated by blue or ultraviolet light, it re-emits it as red, and appears differently than under white light illumination. Biofluorescence may assist ...
