Most objects in the real world are symmetrical. This is particularly true of nature: the radial symmetry of starfish or flower petals, the symmetrical efficiency of a hexagonal honeycomb, or the uniquely symmetrical crystal patterns of a snowflake. In factasymmetryis often a sign of illness or ...
(Allothunnus fallai), the latter found in cooler waters of southern oceans (one was caught in Los Angeles Harbor, though as pelagic-fish expert John Graves, of the Virginia Institute of Marine Science (shown above with a litttle bullet tuna), speculates, it was likely dumped from the bait...

Table 1 Results of the PERMANOVA tests carried out to investigate differences in the quantity and biochemical composition of organic matter between the two matrices (M; sediments vs. feces) subjected to different temperatures (T; 14, 17, 20, 23, 26, 29 °C) in the two sites (S; meso-eu...
about pH5.816; in terms of temperature, the shrinkage temperature (Ts) of most mammalian fibrils is between 62° and 65°, while the shrinkage temperature of fish fibrils is between 38° and 54°. between. On the other hand, the denaturation temperature Tm is 25°C-30°C lower than Ts....
