an optometrist. The term eye doctor refers generally to an ophthalmologist, but is also used informally (and imprecisely) in referring to an optometrist. An ophthalmologist is a physician who specializes in the diagnosis and treatment of diseases of the eye.
Whale Watching Season. The best time for whale watching in Massachusetts is from April to October, although whales have been spotted in Bay State waters as early as mid-March and as late as early November. Whales migrate to Massachusetts to feed on mackerel, herring, krill and other schooling fish that breed in these nutrient-rich waters.
Whale watching is mostly a recreational activity (cf. birdwatching), but it can also serve scientific and/or educational purposes. A study prepared for IFAW in 2009 estimated that 13 million people went whale watching globally in 2008. Whale watching generates $2.1 billion per annum in tourism revenue worldwide, employing around 13,000 workers. The size and rapid growth of the industry has led to complex and continuing debates with the whaling industry about the best use of whales as a natural resource.
