What do fish have in their tissues?
Fish are a diverse group of animals, with over 32,000 species worldwide. They can be found in both freshwater and saltwater habitats. Fish come in many shapes and sizes, but they all share one thing: an interconnected tissue system that transports nutrients throughout the body. This article will explore how these tissues work to keep your favorite finned friends alive!
Fish have a circulatory system. This network of pumps, pipes and valves is the fish’s main supply of oxygenated blood. Blood carries nutrients to all parts of the body as well as removes waste products from cells in order to keep them alive. The heart pushes this vital fluid through the entire organism-top to bottom and side to side!
Every cell group needs special tissue with its own pump for watery fluids (the kidneys), filter systems for solid wastes (livers) or hormone producers that send messages around your body (glands). These tissues are called organ systems, because they work together like organs do inside your human bod.
Placentals: these mammals use their placenta after birth to exchange nutrients and waste products with their developing young.
Marsupials: these mammals have a pouch that they care for their young in after birth, until the joey is developed enough to survive on its own.

What Do Fish Have In Their Tissues? (do fish have blood) Fish have a circulatory system. This network of pumps, pipes and valves is the fish’s main supply of oxygenated blood. Blood carries nutrients to all parts of the body as well as removes waste products from cells in order to keep them alive. The heart pushes this vital fluid through the entire organism-top to bottom and side to side! Every cell group needs special tissue with
a large surface area to absorb oxygen from the blood and provide a place for excess carbon dioxide to be released. These tissues are called gills or lamellae; they’re found in either pouches, such as on sharks’ faces, or all over their skin like fish scales.
Fish also have other specialized tissue types that help them stay buoyant (i.e., lightweight), make sounds by vibrating air bubbles trapped under their skin membranes (i.e., swim bladders), and reproduce using eggs instead of live birth (i.e., oviparity).

The answer is that fish do not have blood. The reason for this goes back to the evolution of vertebrates which had a common ancestor with our earliest ancestors, animals who lived in water like jellyfish and sea anemones. Early on, some species developed two separate circulatory systems: one within their body and another outside used to transport nutrients from external sources along temporary pathways called “veins.”
Vertebrates such as humans lost these veins – they no longer need them because oxygen was able to diffuse into internal tissues once we moved onto land. Fish however retained both sets of vessels so they can live under water where there’s less oxygen available.
So while fish do use red hemoglobin (a protein) o carry oxygen, they also use the blue or green hemocyanin to do this.

Vertebrates such as humans lost these veins – they no longer need them because oxygen was able to diffuse into internal tissues once we moved onto land. Fish however retained both sets of vessels so they can live under water where there’s less oxygen available. So, do fish have blood? Yes, but it’s not in their veins.
Conclusion:
So as we can see, do fish have blood is a question that has two parts and the answer to both questions depends on what type of animal you are talking about. In humans for example only our red cells carry oxygen through arteries, tissues and capillaries because they’re relatively good at carrying large amounts of oxygen while being small enough to move freely around the body without much resistance from other substances such as fat or proteins. This doesn’t work well for sea life though which need lots of oxygen to survive so instead they use hemocyanin in order to transport more than just simple gases like carbon dioxide and nitrogen – these types of molecules
