Yes a whale can have more than one child i believe they could either have 1 or 2 they could even have twins. And when a dolphin gives birth to a baby that baby can have hair.
Dolphins are like us they are mamals so one baby at a time
Yes, dolphins are multicellular organisms.
no one knows.somtimes they will
Dolphins in the sea, and dogs on land. They are both very social animals, dolphins in particular.
a group of dolphins is called a pod.
dolphins have one baby at a time.
They don't. Twins are an example of more than one baby. But from your view, our cells are complicated and to have more than one baby would take much more energy than is sensible.
If you mean do dolphins live for one year then the answer is no, The average life expectancy for the bottle-nose dolphins is about 25 years. the maximum age (which only a few will reach) is more than 40 years.
You can find information about baby dolphins, also known as calves, on the Oracle ThinkQuest website. It tells you how long it takes a baby dolphin to mature and their typical weight and length when they are born.
sometimes but not always ANSWER Dolphins rarely if ever fight with other species of dolphin (with the one exception being Orcinus orca, the killer whale, which may attack dolphins more for sport than as a food source, although this information is anecdotal). Spotted dolphins are not known to be more aggressive than other odontocetes. Check out this website: http://www.acsonline.org
