What animal has 9 hearts?
octopusAn octopus has three hearts, nine brains, and blue blood.
Two hearts pump blood to the gills, while a third circulates it to the rest of the body..
Do giraffes have 3 hearts?
Three hearts, to be exact. There is a systemic (main) heart. Two lesser hearts pump blood to the gills where waste is discarded and oxygen is received. They work like the right side of the human heart.
Does every living thing have a brain?
Not only humans have brains, of course. Almost all animals have a nervous system of some kind (only sponges do not). The brains of different animals are different in some ways but similar in many other ways.
Which animal has no brain and heart?
jellyfishA jellyfish has no ears or eyes or nose and no brain or heart! They do not even have a head. Their body is almost totally made of water and is soft having no bones at all. Jellyfish are invertebrate animals because they do not have a spine or backbone.
What color is shark blood?
crimson bloodFrom timber wolves to tiger sharks, most vertebrate animals have crimson blood in their veins. This hue is produced by hemoglobin, the protein that helps our blood distribute oxygen.
Which animal is dumbest?
SlothsSloths are the slowest and dumbest animals out there.
Can Jellyfish feel pain?
Jellyfish have no brain, heart, bones or respiratory system (their skin is so thin that they can oxygenate by diffusion), and are composed of approximately 95% water. Their nervous system allows them to perceive basic senses like smell and touch. They have no need for any other organs.
How do sponges die?
Sea sponges can only survive in saltwater, so if you put them in freshwater, they will quickly die. They are also very sensitive to air and do not like to be taken out of the water because their pores get filled with air. If too many of their pores are filled with air, they will die.
What is the lifespan of a sponge?
Sponges in temperate regions live for at most a few years, but some tropical species and perhaps some deep-ocean ones may live for 200 years or more. Some calcified demosponges grow by only 0.2 mm (0.0079 in) per year and, if that rate is constant, specimens 1 m (3.3 ft) wide must be about 5,000 years old.
Are kitchen sponges alive?
Animal Sponges Natural sea sponges are living animals in the phylum Porifera. These are the least desirable option for kitchen sponges because the animals have been over-harvested The loss of sponges negatively affects other creatures such as the hermit crab as well as those animals dependent on this crab species.
Can sponges feel pain?
Second, it is possible that only sufficiently advanced non-human animals feel pleasure and pain. This is the most common view: that other creatures such as chimpanzees, dogs, and pigs also have internal experiences, but that there is some cut-off point beyond which species such as clams, jellyfish, and sea-sponges lie.
What animal has green blood?
Credit: Photo by Chris Austin, LSU. Green blood is one of the most unusual characteristics in the animal kingdom, but it’s the hallmark of a group of lizards in New Guinea. Prasinohaema are green-blooded skinks, or a type of lizard.
Which animal blood is black?
The Peanut Worms are marine animals with dark purple coloured blood and can appear almost black. The purple color is due to the protein called Hemerythrin.

Is there any animal that doesn’t have a brain?
Scientists have shown that animals as simple as the roundworm C. elegans, with a brain of just 302 neurons, need sleep to survive. Cassiopea has no brain to speak of—just a diffuse “net” of nerve cells distributed across their small, squishy bodies. These jellyfish barely even behave like animals.
What Colour is snake blood?
redOriginally Answered: What is the colour of blood of a snake? It’s the same red color as human blood, dog blood, cow blood, and most (of not all) other bloods you’ll come across in vertebrates.
What animal has 7 hearts?
Hagfish. Who knew such a nasty creature could have so many hearts? The hagfish has four of them, one main three-chambered systematic heart and three accessory pumps.
What animal has 32 brains?
Leeches2. Leeches have 32 brains. A leech’s internal structure is divided into 32 separate segments, and each of these segments has its own brain. In addition to that, every leech has nine pairs of testes — but that’s another post for another day.
