The milk is a pinkish color but holds lots of nutrients and is made 50%of fat. Then after the 6 months is up, then they are fed still by milk but also a verity of independent ways. A new born cafe can be up to 50ft(15m) so as big as a full grown whales head. They way around 2 tons and grow faster as they eat and respond to feeding on there own.

What the whale does to make this bubble net is that they will swim around an area of prey and make bubbles and keep swimming in circles till the circle gets tighter and smaller so that there prey is in a small trapped area then they just swim up in the middle of the bubble net and open there mouths and take a big gulp of food with them.
