Whale Reproduction Whale Reproduction and Care of Young. Male whales are mature between 7 and 10 years of age. They have a cavity that their genitals remain in during resting and swimming so there isn’t a great deal that is known about them in great deal. For females maturity occurs about 5 to 7 years of age.

- I still have the same feelings, I still see the world the same way. I find it frustrating that all police officers are considered racist, or brutal or corrupt. Police officers are treated with suspicion, and are presumed to be guilty, even before all the information is gathered. It's wrong to prejudge, w...

- Dolphins are mammals, not fish, and they reproduce in the same way that humans and most other mammals do. The males have a penis, to introduce semen to the female's vagina. Fertilized eggs are matured in the dolphin's womb for many months and after about 12 months baby dolphins are born through the ….

Spawn (biology) Marine animals, and particularly bony fish, commonly reproduce by broadcast spawning. This is an external method of reproduction where the female releases many unfertilised eggs into the water. At the same time, a male or many males release a lot of sperm into the water which fertilises some of these eggs.

Whale Shark Whale shark reproduction is largely a mystery, though one female is known to have contained over 300 small “pups” who are likely born in sequence rather than in one huge swarm. Whale sharks reach adulthood at around 30 years of age and may live for up to a century.

- The sperm whale (physeter macrocephalus) is a large toothed whale that is part of the cetacean species, which includes all species of whale, dolphin and porpoise. The sperm whale is the largest of the toothed whales and can grow to be as long as 67 ft. They also have the largest brain out of any animal known to exist.

- A female gives birth to a calf every two to three years and is pregnant for 10 to 12 months before giving birth. Young are born in warm, low latitude waters in the winter months. A baby blue whale averages 23 feet (7 meters) long and 4,400 pounds (1,990 kg) when born. It is fed by its mother's milk for 7 to 8 months.

Whale Whale is the common name for a widely distributed and diverse group of fully aquatic marine mammals. They are an informal grouping within the infraorder Cetacea, excluding dolphins and porpoises, so to zoologists the grouping is paraphyletic.dontocetes feed largely on fish and squid. A few, like the sperm whale, feed on large invertebrates, such as giant squid. Grey whales are specialized for feeding on bottom-dwelling molluscs. Male whales typically mate with multiple females every year, but females only mate every two to three years.

Reproduction Methods Sexual reproduction in seahorses: Female seahorses produce eggs for reproduction that are then fertilized by the male. Unlike almost all other animals, the male seahorse then gestates the young until birth.

Whaling Whaling is the hunting and killing of whales for commercial, recreational or scientific purposes.he moratorium came into effect in 1986. Norway registered its objection to the moratorium and as such is not bound by its rules. It hunts whales for both scientific and commercial purposes-the only nation to openly do so.

- The sperm whale (Physeter macrocephalus) or cachalot / ˈ k æ ʃ ə ˌ l ɒ t, ˈ k æ ʃ ə ˌ l oʊ / is the largest of the toothed whales and the largest toothed predator. It is the only living member of genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.

Whale Gestation Period While it is possible for some species to mate throughout the year the most common time of year for whales to mate/bare offspring is during the colder winter months when various species travel to the warmer tropical environments to mate and give birth.

- The spermaceti organs may also help adjust the whale's buoyancy. It is hypothesized that before the whale dives, cold water enters the organ, and it is likely that the blood vessels constrict, reducing blood flow, and, hence, temperature.ature males average at 16 metres (52 ft) in length but some may reach 20.5 metres (67 ft), with the head representing up to one-third of the animal's length. The sperm whale feeds primarily on squid.

Killer whale  (Orcinus orca) Female killer whales reach sexual maturity when they grow to about 15-18 feet (4.6 m-5.4 m) long, depending on geographic region. The gestation period for killer whales varies from 15-18 months. Birth may take place in any month--there is no distinct calving season. Calves are nursed for at least 1 year, and may be weaned between 1-2 years old. The birth rate for killer whales is not well understood, but, in some populations, is estimated as every 5 years for an average period of 25 years. Killer whales are highly social animals that occur primarily in relatively stable social groups that often range in size from 2 to 15 animals.

Whaling Whaling is the hunting of whales primarily for meat, oil, and blubber. Its earliest forms date to at least circa 3000 BC.Various coastal communities have long histories of subsistence whaling and harvesting beached whales.ommercial whaling ceased for a five-year period to allow a small scientific catch for gauging the stock's sustainability and resumed 1993. Minke whales are the only legally hunted species. Catches have fluctuated between 487 animals in 2000 to 592 in 2007. For the year 2011 the quota is set at 1286 Minke whales.

How does the Goblin Shark reproduce? Reproduction is a species' varying method of passing on traits and genes from one generation to the next, with fertile offspring. When offspring are fertile, they can reproduce as well and continue the cycle. Different organisms do this differently. The most common difference is Asexual and Sexual reproduction. Asexual is the process of reproduction without the help of a partner. This results in a clone of the organism that reproduced.

Fact Sheet: Whale Sharks Whale sharks are viviparous, but they have no yolk placenta (aplacentally viviparous). The often found huge egg capsules are simply premature pups. Whale sharks thus do not lay eggs. The offspring are born in the mother's body out of egg capsules. Up to 300 young have been counted in one female. Their size at birth lies between 55 and 64 cm.

How Does A Whale Shark Reproduce? Answer: Whale shark reproduction process is not known in detail. Initially, whale sharks were believed to be oviparus, as some eggs were found in the bottom of the ocean.Later it was proved that such eggs were not laid by mothers but probably the result of abortions.Further research proved later that they are ovoviviparus, meaning that even that they have eggs, they are kept inside the mother for growing until the pups are fully developed.Eggs hatch inside the mother and pups keep receiving food from their surroundings until they are fully formed.urther research proved later that they are ovoviviparus, meaning that even that they have eggs, they are kept inside the mother for growing until the pups are fully developed. Eggs hatch inside the mother and pups keep receiving food from their surroundings until they are fully formed.

What Is a Baby Whale Called? Birth Seasons. The birth of a new baby whale, known as a calf, usually occurs during the birth season for that specific type of whale. Orcas, for example, tend to give birth in the spring or fall, while blue and humpback whales do so in the winter. Gestation also varies from whale to whale -- with orcas it lasts around 17 months, with humpbacks 12 and with blues 11. Almost all whale births are to single calves, but rare twin births have been observed in wild whales.

- Whales are mammals because they give birth to live young, they have fur (although it is very sparse on their body), they have lungs and breath air and they provide milk for their young. You have a lot of interesting questions about marine mammals. Dolphins and other whales are all mammals called cetaceans.

Animal sexual behaviour When animal sexual behaviour is reproductively motivated, it is often termed mating or copulation; for most non-human mammals, mating and copulation occur at oestrus (the most fertile period in the mammalian female's reproductive cycle), which increases the chances of successful impregnation.

- Whales typically give birth to one calf at a time, although twin fetuses can occur on rare occasions. Mature females of most species, including humpback, beluga and blue whales, usually reproduce every two to three years.The average time between gestation periods for sperm whales is three to four years.ewborn beluga whale calves typically weigh about 175 lbs. A right whale calf's birthweight generally is about 500 lbs. Gray whales weigh 1,100 to 1,500 lbs. at birth.
