Octopuses range in size from 1 cm to more than 5 m in length, while squids range from 1 cm - 20 m. The giant Pacific octopus has a life span of only four to five years, yet it can weigh 270 kg.
When we change our clocks. Most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. In the U.S., each time zone switches at a different time. In the European Union, Summer Time begins and ends at 1:00 a.m.
The end of daylight-saving time will fall on Sunday, Nov. 6, at 2 a.m. At that time clocks will fall back and change from 2 a.m. back to 1 a.m. While some relish the idea of an extra hour of sleep, others dread the early nightfalls that standard time brings. However, the days have been getting shorter since the day after the summer solstice on June 20. The day length will not change drastically with the onset of standard time. For example, Birmingham, Ala., will get 10 hours, 41 minutes and 5 seconds of daylight on Nov. 5 and 10 hours, 39 minutes and 22 seconds on Nov. 6.
