The structure of the vestibular organs of the teleost fish (bluegill), newts (Japanese fire-belly newt), frogs (black-spotted pond frog), snapping turtles and birds (chicks) was morphologically compared, with particular attention to the lagena macula, and the differences between animal species wi...
These different sperms include the sperm from the same clone male (A–F), the sperm from the different clone male (A'–F') and the sperm from male of another species Cyprinus carpio (A''–F''). The corresponding time (min) is shown on the right corner. Thin arrows indicate the rep...

aThere are two treefrogs considered "sibling species". One is a diploid (normal) form; the other is a tetraploid, with four sets of chromosomes, rather than two. The only other way to tell tham apart is by the call. If you have preserved specimens and cannot karyotype them, you cannot...
Foraging success is critical to the survival of any predator. When encountering introduced prey species, predatory generalists often adapt more readily to the prey than do predatory specialists. The foraging and prey handling behaviors of Thamnophis hammondii offered three different prey types (Lepomis...
From these data he argued that the explanatwn of these extraordinary resemblances was to be found in the great advantage it would be to species undefended by offensive secre- tions, and therefore palatable and much hunted down, to find escape in the disguise of species recognised and avoided...
It was shown that the cardiac tissues of tadpoles differ from those of frogs by their antigenic properties (particularly as a result of the presence of the antigens in tadpoles, which are absent in the adult frogs, i.e. of the stage-specific antigens). Cardiac tissues of tadpoles are ...

(1) Experiments were carried out on several species of vertebrates to extend knowledge of spino-bulbo-spinal (SBS) and propriospinal reflexes. (2) Vertebrates studied included the following. Mammals: kangaroo rat, bat, sloth, dolphin, wallaroo, opossum, sheep, seal and mangabey. Birds: chicken...
