I have seen many blue whales swimming in the ocean -- probably about 300
during one 2 weeklong survey.

In general, large whales reach sexual maturity between 5 and 8 years old.

Yes, in general migration patterns are the same year to year but may vary
by a few weeks depending on food availability and other factors.

Interesting question. There is no evidence to answer the question, but it
does seem that whales may stagger their migration depending upon
environmental conditions such as temperature.

I have been about 5 feet away from a humpback whale swimming in Hawaii.

I saw a blue whale that was about 100 feet long!

Rorquals are a group of baleen whales in the balaenopteridae family.  These
include the minke, fin, blue, sei, Brydes and humpback whales.

Megaptera novaeangliae is the latin name for humpback whales (I think that
is the question?)

Sperm whales are very deep divers.

>What are some unique behaviors of the Right whale?  Lucy B.

Right whales are very rare in the North Pacific and North Atlantic oceans.
In both oceans combined, there are less than 600!

>

I like all whales.

>Why do Narwhals have spots on them?   Colin M.

Spots on Narwhals are pigmentation patterns, similar to freckles on people.

>
>How old do right whales get to be?  Jessica M

We do not know this very well. They can live to be at least 50, and maybe
even to 100.

>
>How many whales were seen at one time?Jessica M

I have seen groups of 15 humpback whales feeding together in Alaska.

>
>Which whale has the biggest baleen? Jessica M

The blue whale, because it is the largest whale.

>
>How fast can Right whales travel?  Lee R.

Most whales swim between 4-6 knots withbursts of speeds to catch food or
mates that may be twice that.
