What do lions eat? Where do lions live?

Why do lions have a mane?

The mane has often been viewed as a shield that protects a male's neck during fights against other males, but lions mostly attack each other on the back and hips. Instead, the size and coloration of the mane serves as a signal to other lions about the male's fitness, similar to the showiness of the peacock's tail.

Only male lions boast manes, the impressive fringe of long hair that encircles their heads. Males defend the pride's territory. They mark the area with urine, roar menacingly to warn intruders, and chase off animals that encroach on their turf.

Do lions and tigers have manes?


While the lion's mane does not have a significant protective function in fights with other lions, the tiger's fighting style evolved in the absence of a mane, perhaps conferring an advantage to a lone lion male.

How many cubs do lions have at a time?

How many cubs does a female lion typically have and when are they weaned? Females typically have litters of two or three cubs. Cubs are usually weaned by the age of eight months. You can also check out lion facts for more interesting information about lions.

Where do lions live? Lion habitat

Nearly all wild lions live in sub-Saharan Africa, but one small population of Asian lions exists in India's Gir Forest. Asian lions and African lions are subspecies of the same species.

Asian lions once prowled from the Middle East to India. Now, only 200 to 260 of these magnificent animals survive in the wild. The Gir Forest's dry teak woods were once a royal hunting ground. Today they are a reserve where the endangered Asian lions are heavily protected. An additional 200 Asian lions live in zoos.

What do lions eat?

Practically any animal they can catch. But most of their victims weigh between 50 and 300 kilograms (110-660 lbs). The most common prey are zebras, giraffes, pigs, cape buffalo, antelope and wildebeests.

A single lion kills about 15 large animals each year, filling out its diet with carrion, as well as kills made by other members of the pride. Typically, in the wild more than half their food comes from scavenging.


Lions are fierce animals that require large amounts of food to survive. Sometimes people may wonder what do lions eat to make them so large. Because lions are carnivores, they eat meat and a lot of it.

What do mountain lions eat?

The habitat where mountain lions are found can range from a desert area to a mountain area. Usually if an area has many deer roaming, there just might be a mountain lion hiding nearby waiting to attack since they love to eat this type of animal. What do lions eat besides deer? They prefer to kill animals like elk or livestock, and even some domestic animals may be at risk if a mountain lion is close by. The mountain lion will ambush their prey by attacking from behind.

What do African lions eat?

The African lion hunts medium to large size animals such as wild hogs and zebras. The African lion will try to get close enough to its prey to grab it, but sometimes they will have to run toward the prey, which causes the animals to start running.

What do lions eat in the zoo?

Zoo lions are given mostly beef, sometimes including beef bones. Other types of flesh are also fed, for example, horse meat, but this is much less common.

Do sharks lay eggs? How do sharks mate, give birth

How many types of sharks are there?

There are Around 440 Known Species of Sharks! There are many iconic species of sharks - the Great White in the film Jaws was burned into popular cutlure, for better and for worse - but they are still a very small subsection of the over 400 shark species that have been discovered by humans so far.

Do sharks lay eggs or give live birth?

Sharks exhibit a great diversity in reproductive modes.

There are oviparous (egg-laying) species in nature and viviparous (live-bearing) species. Oviparous species lay eggs that develop and hatch outside the mother's body with no parental care after the eggs are laid. The embryos are nourished by a yolk-sac inside the egg capsule.



Viviparous species can be separated into two categories: placental (having a placenta, or true connection between maternal and embryonic tissue), or aplacental (lacking a placenta). Among the aplacental species, there are those whose embryos rely primarily on a yolk-sac for nutrition during gestation and those that consume yolk-filled, unfertilized egg capsules (oophagy).

Types of Sharks That Lay Eggs
  • Bamboo sharks
  • Wobbegong sharks
  • Carpet sharks
  • Horn (bullhead) sharks
  • Swell sharks
  • Many catsharks
  • Live-Bearing Sharks

About 60% of the shark species give birth to live young. This is called viviparity. In these sharks, the young remain in the mother's uterus until they are born.

The viviparous shark species can be further divided into the ways the young sharks are nourished while in the mother:

How Do Sharks Mate?

All sharks mate through internal fertilization. The male inserts one or both of his claspers into the female's reproductive tract and deposits sperm. During this time, the male may use his teeth to hold on to the female, so many females have scars and wounds from mating. You can check out shark facts for more information.

How do sharks give birth and reproduce?

After mating, the fertilized eggs may be laid by the mother, or they may develop either partially or fully inside the mother. 


Viviparity

The eggs hatch inside the female's body and the babies are fed by a placenta which transfers nourishment from the mother to the babies (via an umbilical cord which is connected to the baby shark behind the between the pectoral fins). The placenta helps transfer nutrients and oxygen from the mother's bloodstream and transfers waste products from the baby to the mother for elimination. Viviparous sharks give birth to live young. The number of pups in a litter ranges from 2-20 or more. Examples of viviparous sharks include the Bull sharks, Whitetip reef shark, Lemon shark, Blue shark, Mako, Porbeagle, Salmon shark, the Silvertip shark, and Hammerheads. Although long thought to be oviparous (an egg 14 inches (36 cm) long was once found), Whale sharks are viviparous and pregnant females have been found containing hundreds of pups.

Oviparity

These sharks deposit eggs in the ocean which will hatch later if they are not eaten by predators. The eggs are not guarded by either parent. Shark eggs (sometimes called "mermaid's purses") are covered by a tough, leathery membrane. Their shape ranges from pouch-like to screw-shaped (like the California hornshark and the Port Jackson shark). Some eggs (like those of catsharks) have tendrils that attach the egg to objects on the sea bed. The egg has a yolk that feeds the embryo, very much like a chicken egg. Oviparous sharks include the Zebra shark, the catsharks, swellshark, the necklace carpetshark, some Epaulette sharks, and the Hornshark.

Aplacental Viviparity (Ovoviviparous)

In these animals, the eggs hatch and the babies develop inside the female's body but there is no placenta to nourish the pups. The pups eat any unfertilized eggs and each other (they are oviphagous). Very few pups in a litter survive until birth due to this form of sibling cannibalism. Great white sharks, sawsharks, Mako, crocodile sharks, Cookiecutter sharks, Pelagic thresher, Greenland shark, Gummy shark, Soupfin shark, Pacific Angelshark, Pygmy sharks, Nurse shark, Tiger shark, and Sand tiger sharks reproduce this way.
