How do beluga whales breed?

Answer 1

This is a reply That I found on another forum that sounds like a prety reasonable answer. Whales have sex in the same way other mammals do. Sort of. The basic

anatomy is the same except that the penis is rectractile; held inside

the body (to avoid drag in the water!) until needed, then it emerges

from the genital slit which is on the underside of the caudal peduncle

(the bit at the back heading towards the tail). Likewise, the testes

are internal, which of course presents some huge problems in terms of

cooling (since heat destroys sperm or limits pserm production), and

cetaceans have developed some remarkable counter-current mechanisms for

cooling the genitals internally.

The penis is fibroelastic rather than vascular, and copulation is

probably very brief (as it is with other mammals that have a

fibroelastic penis - e.g. ungulates like antelope). Copulation itself

has been witnessed in remarkably few cases in large whales. Seen quite

a bit in right and gray whales, and never in humpbacks. Surface

copulation occurs in the former two species sometimes, but presumably

most mating takes place quickly underwater. The penis is curved and has

a mobile tip, so in large whales a male will often extend his penis over

the body of a female (lying upside down at the surface) and into the

vagina.

Now for the fun part. Not all whales are created equal in terms of

genital equipment. Blue whales, which are the largest animals on Earth

(males around 80 feet in many cases, weighing perhaps 100 tons or more)

have a pair of testes that weigh a "mere" 26 kg - remarkably small for

such a giant beast. Right whales are at the other extreme; a male which

may be half the length of a large blue whale male, and weigh a lot less,

has testes wweighing - wait for it! - one ton! Largest in the animal

kingdom. The reason is the mating system, which in right whales in

heavily skewed towards sperm competition (multiple males mating with the

same female and competing to produce as much sperm as possible, rather

than fighting it out on an individual basis the way, say, humpbacks do).

Answer 2

As with all other mammals baby whale are conceived by sexual copulation, the mother then gets pregnant and the baby is born.

Mating season can be quite exciting to observe! Male humpbacks fight for the right to mate. The mating has not yet be documented, neither has the birthing. According to whaling records, many females pregnant had twin fetuses. To date, that has not been witnessed either with humpbacks! As with other cetaceans, it is most likely delivery is tail first so calf won't drown if slow to come down birth canal. Much more research needs to be done with humpback whales!

Answer 3

Beluga whales, like other whales, are mammals, who breed pretty much the way other mammals breed except that they do it in the water.
