V is a small but dramatic letter. It brings us the only mammals that live entirely on blood, the rarest marine mammal on Earth, a wild relative of the alpaca with the finest wool in the world, and a backyard marsupial that faints on cue. There are fewer V animals than most letters — but hardly a boring one among them.
Below: quick facts on the familiar V animals, wild species with links to our full profiles, three spotlights, a comparison table, and kid-friendly FAQs.
Common Animals That Start With V
The V animals worth knowing, one fast fact each.
- Vampire bat — the only mammal that feeds entirely on blood — and it shares meals with hungry friends.
- Vulture — nature’s cleanup crew, soaring for hours on rising warm air without flapping.
- Vole — a round-faced little rodent that tunnels under lawns and snow.
- Viper — a venomous snake family with heat-sensing abilities and hinged, folding fangs.
- Vervet monkey — an African monkey with different alarm calls for eagles, snakes, and leopards.
- Vicuña — the wild ancestor of the alpaca, whose wool is among the finest natural fibers on Earth.
- Vaquita — the world’s rarest marine mammal — a tiny porpoise from the Gulf of California.
- Virginia opossum — North America’s only marsupial, famous for playing dead.
- Vinegaroon — a whip scorpion that sprays a vinegar-smelling mist when bothered — startling but harmless.
- Velvet worm — an ancient walking “worm” with stubby legs that squirts slime nets to catch prey.
- Vampire squid — a deep-sea softie despite the name — it eats drifting particles, not blood.
Wild Animals That Start With V
Three V animals have full profiles here on World Deer, and a few others deserve a longer look.
Vampire bats are gentler than the movies suggest: a feeding takes about 20 minutes and rarely wakes the animal. Even more surprising, well-fed bats regurgitate meals for colony-mates who failed to find food — a rare example of animals sharing with non-relatives.
The Virginia opossum is the V-name of the animal most Americans just call a possum. It has more teeth than any other North American land mammal — 50 of them — and a prehensile tail it uses like a fifth hand.
The variegated squirrel of Central America is one of the most colorful squirrels anywhere — one animal can mix black, white, rust, and gray, and no two look quite alike.
The vicuña was nearly hunted out for its wool, which is so fine that a single scarf can cost thousands of dollars. Today, Andean communities round up wild vicuñas every few years, shear them gently, and release them — an ancient tradition called the chaccu.
The vaquita is smaller than most humans and lives only in a tiny corner of Mexico’s Gulf of California. Fewer than a couple dozen remain, making it the most endangered marine mammal in the world — its story is a powerful reason to care about fishing methods.
Vervet monkeys are famous in science because their alarm calls work like words: an “eagle” call sends the troop diving for cover, while a “snake” call makes everyone stand tall and scan the grass.
Vultures deserve far more love than they get. Their stomach acid is strong enough to destroy anthrax and rabies germs, which means every carcass a vulture cleans up is a disease outbreak that never happens. The bearded vulture of the mountains goes a step further — it eats bones, dropping big ones from the sky to crack them open.
More V Animals Worth Knowing
A few more V animals — including two of the most surprising rabbits and rodents in the Americas.
- Viscacha — a South American rodent that looks like a sleepy rabbit with a curled tail; it sunbathes on rocks in groups.
- Volcano rabbit — one of the world’s smallest rabbits, living only on the slopes of a few Mexican volcanoes — it squeaks instead of thumping.
- Visayan warty pig — a critically endangered island pig from the Philippines; boars grow spiky “mohawk” manes in breeding season.
- Vulturine guineafowl — Africa’s most glamorous guineafowl, with a cobalt-blue chest and a bare vulture-like head.
- Viperfish — a deep-sea fish with teeth so long they do not fit inside its mouth.
- Vine snake — a pencil-thin snake that sways like a twig in the breeze to stay invisible.
- Water vole — the beloved “Ratty” of The Wind in the Willows — a chubby riverbank rodent (V by its full name).
- Vampire finch — a Galápagos finch that sometimes sips blood from seabirds when food is scarce — Darwin’s strangest finch.
Spotlight: V Animals We Cover in Depth
Vampire Bat: The Blood Donor
Vampire bats are small — about the size of a plum — and they walk, hop, and even sprint on the ground, which is rare for bats. Heat sensors in their noses find where blood flows close to the skin.
Their saliva contains a clot-preventing protein scientists actually named “draculin,” now studied for stroke medicine. Get the full story in our vampire bat profile.
Virginia Opossum: The Unsung Hero of the Backyard
The Virginia opossum shrugs off snake bites that would harm a dog, eats ticks by the thousands, and almost never carries rabies. Mothers carry up to 13 honeybee-sized babies in a pouch, then give piggyback rides.
Its dramatic “death” act — stiff body, lolling tongue, awful smell — is an involuntary faint. Meet the whole family in our opossum guide.
Variegated Squirrel: A Different Coat on Every Tree
From Mexico to Panama, variegated squirrels patrol treetops in a patchwork of colors so varied that early naturalists mistook different individuals for different species.
They rarely drink, getting most of their water from fruit and dew. See what else makes them special in our variegated squirrel profile.

Eight V animals at a glance — from the blood bank to the deep sea.
| Animal | Type | Habitat | Fun fact |
|---|---|---|---|
| Vampire bat | Mammal | Latin American caves and forests | Shares blood meals with hungry colony-mates |

| Vole | Rodent | Fields and lawns of the Northern Hemisphere | Digs tunnel networks under winter snow |
| Vampire squid | Cephalopod | Deep ocean worldwide | Despite the name, it eats drifting specks — not blood |
Frequently Asked Questions
Do vampire bats bite people?
Very rarely. Vampire bats mostly feed on sleeping livestock like cattle and pigs, taking about a spoonful of blood at a time — the animal usually never notices. Bites to humans can happen in places where bats and people live close together, which is one reason rabies vaccination programs matter.
What is the rarest animal that starts with V?
The vaquita, a shy little porpoise from the Gulf of California in Mexico. Scientists estimate only a few dozen — at most — are left, because they get tangled in illegal fishing nets set for a fish called the totoaba. It is the most endangered marine mammal in the world, and conservation teams are racing to remove nets from the small patch of sea where the last vaquitas live.
Why do opossums play dead?
It is not really a choice — extreme fear makes the opossum faint automatically. Its body goes stiff, its tongue hangs out, and it releases a rotten smell. Most predators lose interest in “spoiled” food and wander off, and the opossum wakes up later, completely fine.
