Top 10+ do fish have hemoglobin in their blood

Amidst all the hysteria surrounding the seemingly unstoppable COVID-19, we bring you a story of a fish without blood. In 1928 a biologist sampling off the coast of Antarctica pulled up an unusual fish. It was extremely pale (translucent in some parts), had large eyes and a long toothed snout, and somewhat resembled a crocodile … Read more

In Animal Kingdom, Blood Comes in a Rainbow of Colors Blood isn’t always red—evolution has given rise to a variety of hues. Society elites aren’t the only blue bloods. Several species of octopus have blue, rather than red, fluid running through their veins. The blue comes from a copper-rich protein called hemocyanin, which carries oxygen … Read more

Which fish lack hemoglobin in their blood as adults? The crocodile icefish or white-blooded fish (Channichthyidae) comprise a family of notothenioid fishes found in the Southern Ocean around Antarctica. They are the only known vertebrates to lack hemoglobin in their blood as adults. Icefish populations are known to reside in the Atlantic and Indian sectors … Read more

The Evolutionary Quirk That Allows Antarctica’s Icefish To Survive Extreme Cold Unique adaptations allow the ambush predator to thrive in an environment that would kill most other organisms. This story is excerpted and adapted from Bill Schutt’s PUMP: A Natural History of the Heart, published in September 2021 by Algonquin Books of Chapel Hill. All … Read more

Abstract Animals inhabiting extreme environments allow the powerful opportunity to examine adaptive evolution in response to diverse pressures. One such pressure is reduced oxygen, commonly present at high-altitude and subterranean environments. Cave-dwelling animals must also deal with darkness and starvation, both of which have been rigorously studied as key forces driving the evolution of cave-associated … Read more

From Quanta Magazine (find original story here). In February, a genomics study appearing in Nature Ecology & Evolution drew attention to the bizarre Antarctic blackfin icefish, which swim in the brutally cold waters off the coast of the southernmost continent. The icefish of the Channichthyidae family are unusual in several ways—they lack scales and have … Read more

We don’t have your requested question, but here is a suggested video that might help. Reflective Coatings and Herring.
