Bowhead whale eyes tell story of life at sea, documenting environmental factors

One way to determine the approximate age of a bowhead whale is by looking at changes in their eye lens. This, combined with other methods can help scientists tell how the whales are doing, and what kinds of environmental changes may be affecting them over the course of the bowhead’s lifetime. Sitka high school students recently had a chance to play scientist and do their own eyeball dissections as part of the Sitka Whalefest science in the schools program.
