Vampire Bat This type of bat, of which there are three species, is the only known mammal whose diet is solely based on blood. Although livestock, birds, and reptiles are its typical targets, humans are occasionally its prey.
Vampire bats aren't the only sanguivores. Plenty of fish, worms, insects, arachnids and even birds also drink blood.

Bats have long been linked with Count Dracula, but there's only one type that exclusively feeds on blood. All three species of vampire bat live in Latin America. They seldom attack humans – much preferring livestock such as cows and goats that barely notice the fly-by diners.
Despite all the challenges that go with it, the practice of eating blood — usually called hematophagy — is reasonably widespread in the animal kingdom. Around 300 to 400 insect species drink blood, as do a good number of leeches and fish. Even some birds turn vampiric from time to time.
Type One vampires are the rarest and most powerful type of vampires. They are human-like in appearance but have two fangs and sometimes, their eyes glow. They possess great strength and speed, an incredibly long lifespan and the ability to hypnotize their victims with their eyes.
She has taught science courses at the high school, college, and graduate levels. The hippopotamus or hippo mystified ancient Greeks because it appeared to sweat blood. Although hippos do sweat a red liquid, it isn't blood. The animals secrete a sticky liquid that acts as a sunscreen and topical antibiotic.
All mammals and birds are capable of generating this internal heat and are classed as homoiotherms (ho-MOY-ah-therms), or warm-blooded animals.
A comparable study on chimpanzees found that bees had the worst memory, with a recall duration of just 2.5 seconds. Also earning bees a spot on the list of top 10 animals with the worst memory in the world.
In general, normal blood temperature is about the same as normal body temperature, or about 98.6℉ (37℃). Blood outside of the body will remain the same temperature for only a few minutes.
Octopuses and squids (animals called cephalopods) have three hearts. Two hearts pump blood to the gills to take up oxygen, and the other pumps blood around the body (Figure 1).
One group of segmented marine worms has pink blood. This is because the molecule that carries the oxygen is a type of blood pigment, known as hemerythrin, which is described as pink or purple.
Did anyone know that some animals have blue blood, especially when it is exposed to oxygen? 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.
Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood. Their body cavity has no lining or fluid within it.
Lampreys use their suction-cup-like mouths to attach to other fish and feed off their blood. Their prey is often left for dead, giving the lamprey the moniker "the vampire fish." The U.S. Fish and Wildlife Service spends $20 million annually to control the jawless fish.
Butterflies will drink blood, among many other liquids, due to the minerals found in it. Some butterflies, such as the monarch and painted lady, migrate to find warmer climates.
In Animal Kingdom, Blood Comes in a Rainbow of Colors. The Antarctic octopus, pictured, has a copper-rich protein in its blood that turns the vital fluid blue. Please be respectful of copyright.
Indeed, most mammal, fish, reptile, amphibian, and bird blood is red because of hemoglobin, whose protein is made of hemes, or iron-containing molecules that fuse with oxygen.
Sea squirts have purple blood. And a few rare animals have blood that is completely color- less. So what is the reason for all of these different colors of blood in animals? The blood of a horseshoe crab is blue because of a mol- ecule called a respiratory pig- ment.
Answer: The female black rhinoceros or Diceros bicornis give black milk. Explanation: Black milk is the slimmest milk containing very little amount of fat (0.2%) is produced by Black rhinoceros.
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.
The short answer is ants have something similar to blood, but scientists call it “haemolymph”. It is yellowish or greenish. In vertebrates (animals with backbones such as humans, cats, dogs, snakes, birds and frogs) blood's main job is to move important things around the body.
There are also numerous animals with no hearts at all, including starfish, sea cucumbers and coral. Jellyfish can grow quite large, but they also don't have hearts. Or brains. Or central nervous systems.
There are a number of marine species that outlive humans, and the mammal species that holds the record for longevity is the bowhead whale, which can live for 200 years - or more.
