Wild animals that start with E
A few of these E animals deserve more than one line. Here are the wildest stories behind the letter.
Elephant seal
Male southern elephant seals are the biggest seals on Earth — the largest bulls can weigh several tons, more than a pickup truck. They dive deeper than almost any other mammal, hunting squid thousands of feet down in the dark. The inflatable, trunk-like nose that gives them their name works as a built-in megaphone during beach battles.
Etruscan shrew
The Etruscan shrew is the lightest mammal alive, weighing about as much as a small coin. Its heart can beat over a thousand times a minute, and it must eat close to its own body weight in insects every day just to stay alive. Blink and you’ll miss it — it hunts in fast, twitchy bursts.
Eastern wolf
The Eastern wolf of Ontario and Quebec is a scientific puzzle: it carries a mix of wolf and coyote ancestry, and researchers still debate whether it’s a full species. It’s smaller than the gray wolf, with a reddish tinge behind the ears. Algonquin Provincial Park is its most famous stronghold.
Eurasian otter
The Eurasian otter patrols rivers across Europe and Asia, closing its ears and nostrils to hunt fish underwater. Otters are famous for play — sliding down muddy banks over and over for no obvious reason except fun. After decades of decline, cleaner rivers have helped them return to much of Europe.
Echidna
The echidna is one of nature’s strangest success stories: a mammal that lays a single soft-shelled egg, then carries the hatched baby — called a puggle — in a pouch-like fold. Its body is covered in spines, and its sticky tongue flicks in and out of ant nests. Echidnas and platypuses are the only egg-laying mammals left on Earth.
Emu
The emu is Australia’s biggest bird, nearly six feet of shaggy feathers on tireless legs that can cruise at 30 miles per hour. Fathers do all the parenting: a male incubates the dark-green eggs for about eight weeks, barely eating, then guards the striped chicks for months. Emus swallow pebbles to help grind food in their gizzards, and in 1932 Australia famously lost a military campaign against them — the ‘Emu War.’

These E animals have full World Deer guides behind them — perfect for reports and rabbit holes.
Elk
The elk, or wapiti, is one of the largest deer in the world — a big bull can weigh 700 pounds or more and carry antlers spanning four feet. In September, mountain valleys ring with bugling: an eerie, whistling scream bulls use to challenge rivals and attract cows. Our elk cluster covers everything from what elk eat to where the biggest herds roam.
Elephants
Our elephant guides cover the largest land animals alive: African savanna elephants, African forest elephants, and Asian elephants. Elephants recognize themselves in mirrors, comfort distressed herd members, and communicate through rumbles too low for human ears. Herds are led by the oldest females, walking libraries of where to find water in drought.
European hedgehog
The European hedgehog carries around 5,000 to 7,000 spines and rolls into a nearly perfect ball when threatened. It’s a gardener’s best friend, patrolling flowerbeds at night for slugs, beetles, and caterpillars, and it hibernates through the cold months in a leaf nest. Our profile covers its diet, hibernation, and how to help hedgehogs in your own yard.

Questions kids ask about E animals
What’s a cool animal that starts with E?
The echidna is a great pick: a spiny mammal that lays eggs and carries its baby — adorably called a puggle — in a pouch. On the opposite end of the size scale, the Etruscan shrew is the lightest mammal on Earth, with a heart that can beat over a thousand times per minute.
What sound does an elk make?
Bull elk make a sound called a bugle — a strange, rising whistle that ends in deep grunts. It’s one of the loudest calls of any deer and can carry for miles through mountain valleys. Bulls bugle mostly in September and October during the rut, when they’re gathering cows and warning off rival males.
What’s the smallest animal that starts with E?
The Etruscan shrew — and it’s the lightest mammal alive, period, at around 2 grams, less than a penny. It’s so small and burns energy so fast that it has to eat almost constantly, downing close to its own body weight in insects every single day.
Do elephants really never forget?
They forget some things, like everyone — but elephant memory is genuinely remarkable. Herds are led by the oldest female, and researchers have shown these matriarchs remember distant waterholes from droughts decades earlier and can recognize the calls of dozens of individual elephants. That long memory is a survival tool: in hard years, the herd that remembers where water was last time is the herd that lives.
E is the letter of extremes — the heaviest land animal and the lightest mammal, a bugling giant and an egg-laying oddball. Each linked profile above goes much deeper, with the kind of detail that turns a list entry into a full report topic.
