3. **Is The blue whale endangerd** Even though they are the largest animal on Planet Earth, Blue whales are very fast whales. So in the early days of whaling, when the whaling ships depended on sail or steam for power, very few blue whales were killed. During the 1930's some fast diesel-powered whaling ships were built and blue whales began to be killed in large numbers. Then during WWII whaling stopped for a while, but after the war, the US actually helped Japan build a modern, fast whaling fleet. Norway and several other countries did the same, and by the late 1950's tens of thousands of blue whales were killed each year, until by the early 1960's they were almost all gone. The only way they knew that almost all the blue whales had been killed was a measurement called "catch per unit of effort" or CPU. In other words, when they couldn't find any more, they figured they must have killed nearly all of them. Blue whales don't reproduce very fast, so it's possible that they haven't increased their numbers much since the 1960's. That's why they are considered endangered.

Hawaiian monk seals face several natural perils. Sharks prey on these meaty creatures. Also, seals sometimes kill off their own in what is referred to as "mobbing;" violent adult males may attack pups and females during the species' mating season. The food-borne disease ciguatera, the contaminating toxins of which bioaccumulate in small organisms and magnify as they travel up the food chain, infect the seal's food sources and poison seals that ingest them.
