It is an octopus. Yes, the multi-tentacled creature that has always intrigued us has three hearts and nine hearts. Read on to know why. The two hearts of this creature are made for the gills and are used to pump blood.
Such an enormous pressure would require a very large, strong and slow-beating heart. But, they postulate, instead of a single large heart, the Barosaurus probably had some eight hearts.
Octopuses or octopi (both are technically correct) are one of the most well-known animals with multiple hearts.
To many, leeches are horrifying creatures. To a few, they're impressive and miraculous. They have 32 brains, 2 hearts, 300 teeth grouped in 3 jaws, five pairs of eyes...
Octopuses have three hearts, which is partly a consequence of having blue blood. Their two peripheral hearts pump blood through the gills, where it picks up oxygen.
The icefish of the Channichthyidae family are unusual in several ways — they lack scales and have transparent bones, for example — but what stands out most is their so-called white blood, which is unique among vertebrates.
What animal has purple blood? Peanut worms, which are a kind of marine worm, have purple blood. This is due to the presence of hemerythrin, an oxygen-binding protein.
Snails have more teeth than any animal.
A snail's mouth is no larger than the head of a pin, but can have over 25,000 teeth (but these aren't like regular teeth, they are on its tongue).
Pigs like other mammals have a four-chambered heart. The right side of the heart pumps blood to the lungs (pulmonary circulation), and the left side pumps blood out to the rest of the body (systemic circulation).
There is a systemic heart, the main heart, and two lesser hearts that pump blood to the gills where waste is discarded and oxygen is received. They are also the world's tallest mammals.
Q: What has 13 hearts, but no other organs? ... ... A: A deck of playing cards.
Spiders usually have eight eyes but few have good eyesight.
Some spiders have median eyes that can detect polarised light and they use this ability to navigate while hunting.
Cockroaches have a 13-chambered heart that is long, thick, and muscular. A single heart is represented by each chamber. It can be found in the hemocoel's pericardial sinus. Each chamber of the heart receives oxygenated blood from the dorsal sinus through a pair of Ostia or valvular holes.
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
Explanation: Black milk is the slimmest milk containing very little amount of fat (0.2%) is produced by Black rhinoceros.
Answer. The answer is Deck of cards.
This three-eyed animal is called a tuatara. The third eye of a tuatara, located on the top of its head, has all of the right parts: a lens, a retina, and nerves leading to the brain.
Horses, like other mammals, have only one heart. However, the frog in each hoof acts like a pump to push blood back up the leg with each step a horse takes.
One of its four hearts, a branchial heart, pumps blood to the entire body while the other three are considered accessory pumps. They thrive on the bottom of the ocean floor, where oxygen is scarce, scavenging for fish or even dead carcasses to feed on.
Based on the discovery of a single tooth, researchers say they have identified an ancient species of giant platypus.
Can you guess what animals might have blue blood? Lobsters, crabs, pillbugs, shrimp, octopus, crayfish, scallops, barnacles, snails, small worms (except earthworms), clams, squid, slugs, mussels, horseshoe crabs, most spiders. None of these animals have backbones. Some of these animals are Mollusks, like the snails.

Other animals naturally have no tongues, such as sea stars, sea urchins and other echinoderms, as well as crustaceans, says Chris Mah via email.
Earthworms are invertebrates, which means they do not have a backbone. In fact, they don't have any kind of bones, legs, eyes, or teeth.
Giraffes have no vocal cords.
