Seahorse fathers break all the rules—they're the onces who get pregnant and give birth. After the seahorse mother deposits her eggs into the father's pouch, the father fertilizes the eggs and incubates them until he gives birth to the tiny, fully-formed seahorses. This happens after about 20 to 28 days of pregnancy.
In all of the vast animal kingdom spanning the planet, seahorses (and their pipefish and sea dragon relatives) are the only species whose male members give birth to young.
Aristotle is known as the father of zoology. Zoology is a branch of biology that deals with animals' life, evolution, anatomy, physiology, and behavior. Aristotle is also known as the father of biology, he was an ancient Greek philosopher.
Asian Arowana
Male arowanas carry their marble-like eggs (known as their “brood”) in their mouths for several weeks. After hatching, these small fish, or “fry,” continue to live in their father's mouth until they're old enough to feed on their own.
Deadbeat Dads
But the funny thing is, contrary to popular culture, male lions do not take an active role in raising their children. In fact, they are pretty lazy. The female lions in the pride do all the hunting and killing for the family unit, with the male defending his territory against intruders and scavengers.
Although giraffes are social animals, they don't form lasting relationships with partners or family members. That means the young ones will only stay with Mom -- Dad doesn't stick around -- as long as necessary to learn surviving skills.
#7: Red Fox
Male red foxes are doting and indulgent dads, and they enjoy playing and roughhousing with their pups, as most dads do. While the pups are young, the father hunts every day, providing a food delivery service to the den for the cubs and their mother.
Some lions hunt humans because of a lack of other natural prey, while others simply seem to like how people taste. But while it's unusual, baby attacks do happen.
A lion would almost certainly win in a fight against a gorilla. The reasoning should not be all that surprising. A lion will stalk and ambush a gorilla in the dense vegetation of their natural habitat by waiting until it's dark to have the edge. They have a good chance at ending the fight in seconds.
process that lasts only about 17 seconds. They can. keep this up for around four to five days.
Elephants are the largest land mammals in the world, so it's perhaps not surprising that they have the longest pregnancy of any living mammal: African elephants are pregnant for an average of 22 months, whilst for Asian elephants it's 18 to 22 months.
Squirrel monkey infants have such large heads compared to the size of their mothers' pelvises that they face a very high rate of birth complications. Perhaps the most horrifying birth is that of the spotted hyena.
The shortest known gestation is that of the Virginian opossum, about 12 days, and the longest that of the Indian elephant, about 22 months.
Also knows as Platypus frogs, the female amphibian, after external fertilization by the male, would swallow its eggs, brood its young in its stomach and gave birth through its mouth.
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.
Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater. These odd “monotremes” once dominated Australia, until their pouch-bearing cousins, the marsupials, invaded the land down under 71 million to 54 million years ago and swept them away.
Recent molecular evidence shows that dogs are descended from the gray wolf, domesticated about 130,000 years ago.
During copulation, the male inseminates the female. The spermatozoon fertilizes an ovum or various ova in the uterus or fallopian tubes, and this results in one or multiple zygotes. Sometimes, a zygote can be created by humans outside of the animal's body in the artificial process of in-vitro fertilization.
There is archaeological evidence dogs were the first animals domesticated by humans more than 30,000 years ago (more than 10,000 years before the domestication of horses and ruminants).
The swamp wallaby is the only mammal that is permanently pregnant throughout its life according to new research about the reproductive habits of marsupials. Unlike humans, kangaroos and wallabies have two uteri. The new embryo formed at the end of pregnancy develops in the second, 'unused' uterus.
Elephants may be the most protective moms on the planet. Herds of females and children usually travel together in a circle with the youngest member on the inside, protected from predators. If one child becomes an orphan, the rest of the herd will adopt him. Elephants also mourn their dead.
Because snakes swallow their food whole, the mother can't really feed her offspring, and they forage for themselves after they disperse. Pitvipers are the only snakes known to care for their living young; other snakes with parental care limit themselves to care of their eggs.
Foxes are not dangerous and do not attack humans, except when they are rabid, which is very rare, or when they are captured and handled.
