the ocean's surface is lit bu sunlight. the top 30 meters is
brightly lit but it gets darker as you go deeper
down by 200 meters, all sunlight has gone & the water looks bluey-black
flying fish has an unusual way of escaping predators. when
threatened it swims straight at the surface on the water &
flies into the air, using its fins like wings
it can glide above the surface for up to 100 meters
surface wave - when the wind blows over the surface of
the ocean it creates waves. as the waves grow larger they
are moved along the wind, and this helps to mix up the water
during storms at sea, normally the waves reach 30 meters
or more in height. that's as tall as a 10-story building!

Exocoetidae known as flying fish, are a marine fish family comprising about 64 species grouped in seven to nine genera
Flying fish are found in all of the major oceans, particularly in the warm tropical & subtropical waters of the Atlantic, Pacific & Indian oceans
Their most striking feature is their pectoral fins which are unusually large, and enable the fish to hide and escape from predators by leaping out of the water, taking short glided flights through air just above the water's surface
Their glides are typically around 50 m (160 ft), but they can use updrafts at the leading edge of waves to cover distances of at least 400 m (1,300 ft)
In order to glide upward out of the water, a flying fish moves its tail to up to 70 times per second,which "vibrates" to produce enough speed to burst through the surface. It then spreads its pectoral fins and tilts them slightly upwards to lift itself to glide through the air
take off..
its a bird, its a plane.. its a flying fish!
azimCF - what bait do they fancy?
hafiCF - how does it feel to hook them?
abgCF - how to catch them?
