A blue whale can have ONE calf every 2-3 years, if twins are born one out of them will usually live.
Birds and whales are most commonly known for doing this.
Probably a dark blue bird.But blue and black birds don't mate, they only mate their own kind! or, (second answer) where do you think purple martins come from?
Other than attracting a mate, no.
Passenger pigeons are now extinct. However, many kinds of pigeon do mate for life.
At least once a year is the number of times that a grasshopper can reproduce. The answer may vary depending upon location and species. For example, red-legged grasshoppers (Melanoplus femurrubrum) tend annually to mate twice in the southern United States and even three times in Florida.
No. Blue whales only mate with other blue whales.
Yes, it takes three whales to mate. One is instrumental in lining them up.
yes they can but it depends wich whale is female No, killer whales and blue whales differ in size greatly, also, Killer whales (Orcas) are actually Dolphins.
whales mate with other whales of the same species.
How do male killer whales not mate with his mother or sisters
How stupid are u they eat sleep excreet and mate in water :L
Any animal can physically mate with another animal of a different species, but two animals of different species cannot reproduce. The definition of a species is 'a taxonomic group whose members can interbreed'. There are some exceptions (e.g. Horses and donkeys, which can interbreed to produce mules), but whales are not one of them. While blue whales and orcas are both whales, they are two different species of animal, therefore they cannot reproduce. By sheer difference in size if nothing else this would be impossible. BUT Killer whales or Orcas are not whales but actually Dolphins.
Although it's now illegal to hunt blue whales, humans are still the biggest threat for blue whales. They sometimes collide with ocean vessels or get entangled in fishing gear, sometimes leading to their death. Also the sound pollution in the ocean makes it harder for blue whales to communicate, and therefor mate. Apart from humans, orcas have been known to attack blue whales.
Gestation periods for whales are usually between 10-14 months. Blue whales mate in autumn and have a 10-12 month pregnancy.
Sure they do. Its the only way they have to make new whales
find food and migrate to mate
Killer whales have more than one mate, as they are polygamous.
