Considered by many scientists the fastest fish in the ocean, [8] sailfish grow quickly, reaching 1.2–1.5 m (4–5 ft) in length in a single year, and feed on the surface or at middle depths on smaller pelagic forage fish and squid. Sailfish were previously estimated to reach maximum swimming speeds of 35 m/s (125 km/h), but research published ...
Fish with low inbreeding showed almost twice the aggressive pursuit in defending territory than fish with medium inbreeding, and furthermore had a higher specific growth rate. A significant effect of inbreeding depression on juvenile survival was also found, but only in high-density competitive environments, suggesting that intra-specific ...
In some organisms, sexual reproduction has been shown to enhance the spread of parasitic genetic elements (e.g. yeast, filamentous fungi). [80] Bacterial conjugation is a form of genetic exchange that some sources describe as "sex", but technically is not a form of reproduction, even though it is a form of horizontal gene transfer.
Some plant species also exhibit dimorphism in which the females are significantly larger than the males, such as in the moss Dicranum [141] and the liverwort Sphaerocarpos. [142] There is some evidence that, in these genera, the dimorphism may be tied to a sex chromosome, [142] [143] or to chemical signalling from females. [144]
Both women and men are capable of performing extraordinary feats, but there are some things the females of our species do better. Here are 7 of them, according to science. Number 7. Seeing colors ...
Sexual reproduction has many drawbacks, since it requires far more energy than asexual reproduction and diverts the organisms from other pursuits, and there is some argument about why so many species use it. George C. Williams used lottery tickets as an analogy in one explanation for the widespread use of sexual reproduction. [36]
Zangroniz said studies only use a few species of fish and don't represent the more than 30,000 fish species that exist. She added pain is measured in mammals on the grimace scale, often seen in ...
