Stingrays eating Lionfish Heads

Lionfish are an invasive species in the Caribbean posing a real threat to the native fish-population as they have no aquatic predator. Furthermore their reproductive cycle is ridiculously high. They are mature within 6 months and spawn up to 30,000 eggs monthly and even more frequently.

TIME, Angles and direction

 

 

Drag the minute and hour hand around the clock. See the 12 hour and 24 hour clock change as you change the hands. You can even change the clock 'mode' to show angles and fractions of the clock. This works really well on both tablets as well as laptops. Have fun learning to tell the time.
