Whales

Whales are the biggest animals known. The blue whale can reach 80 feet long! Even though they are huge, whales are usually friendly. It is people who are a threat to whales.

Whales strain plankton from the sea or they eat fish. Killer whales do eat squid and sometimes seals and otters too.

Whales make lots of noises. We call them whale songs. One song may last as long as 35 minutes. Try holding a note for that long!
