NORWAY LEMMING BABIES: 192.
Male seahorses possess the remarkable ability to give birth to thousands of babies at once.
The moment a male hippocampus whitei, also known as a White's Seahorse, gave birth to around 100 offspring has been caught on camera at Sea Life Sydney Aquarium. The babies of this endangered species, similar in size to a grain of rice, emerged from their father's pouch.
While most mammals also require a break between pregnancies, either to support new young or during periods of seasonal lack of resources, the female swamp wallaby is the only one that can claim the reproductive feat of being permanently pregnant throughout its life.
Which animal gives birth only once in a lifetime? A female octopus lays eggs only once in her life. She (usually) stops eating to care for them and dies either just before, or just after they hatch.
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
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.
How many babies were born during the longest recorded human pregnancy? The longest recorded human pregnancy was 375 days, or just over 12 and a half months, according to Guinness World Records. During this pregnancy, a woman named Beulah Hunter gave birth to a healthy baby girl in 1945.

Norway lemmings start early. A female can get pregnant at just two weeks old.
Elephants have the longest gestation period of all mammals, carrying their young for 18 to 22 months before giving birth. Long developmental periods are common among highly intelligent animals.
Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
A blue whale's mammary glands are the largest in the world. The breast of a blue whale is just 5 feet long and as big as a tiny human, but it weighs 250 pounds, the same as a baby elephant. The inverted breasts on all blue whales only come out when the newborn whale stimulates them. Milk is thrown at them.
Spiders usually have eight eyes (some have six or fewer), but few have good eyesight. They rely instead on touch, vibration and taste stimuli to navigate and find their prey.
Large mammals, such as primates, cattle, horses, some antelopes, giraffes, hippopotamuses, rhinoceroses, elephants, seals, whales, dolphins, and porpoises, generally are pregnant with one offspring at a time, although they may have twin or multiple births on occasion.
It depends on the animal. While the combination of long labor times, big infant heads, and narrow maternal hips is often cited as a particular challenge for human mothers, some other mammals face difficulties that may be just as painful.
Women can reproduce for about half of their lifetime and can only give birth about once every year or so. So it makes sense that women can only have a fraction as many children as men. One study estimated a woman can have around 15 pregnancies in a lifetime.
Cichlids hold fertilized eggs in their mouth.
Cichlids are from the large fish family called Cichlidae, which includes tilapia and angelfish. When they reproduce, the male puts the fertilized eggs in his mouth, which is where they stay until hatching. This process is called mouthbrooding.
Many species of fish, like the kobudai, are known as “sequential hermaphrodites”: they can switch sex permanently at a specific point in their lives. The majority of “sequential hermaphrodites” are known as “protogynous” (Greek for “female first”): they switch from female to male.
The platypus (Ornithorhynchus anatinus) has a puzzling array of features. Not only does it have that iconic duck bill, it lays eggs like a bird or reptile but feeds milk to its young like a mammal.
James Elgin Gill was born in Ottawa, Ontario, on May 20, 1987, around 128 days early or 21 weeks gestation. He set a record when he was born for the world's most premature baby.
Cheyenne, who has dark hair and blue-green eyes, isn't the smallest baby ever born. That honor rests with Kwek Yu Xuan, who was born at 7.5 ounces — the weight of an apple — in June 2020 in Singapore.
Maria del Carmen Bousada de Lara is the oldest verified mother; she was aged 66 years 358 days when she gave birth to twins; she was 130 days older than Adriana Iliescu, who gave birth in 2005 to a baby girl. In both cases, the children were conceived through IVF with donor eggs.
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.
Snails, spiders and octopi have something in common- they all have blue blood! We're not talking in the sense of royalty, these creatures literally have blue blood. So why is their blood blue and ours red? One of the purposes of blood is to carry oxygen around the body.
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.
