AND SPEAKING OF LIGHT ...

GENE THERAPY PRODUCES BRIGHT CATS

Scientists create glowing mice, rats, and cats by supplying them with jellyfish genes. They do not aim to make the animals light up, but to study other genes. The glow- cat was created by the Mayo Clinic in the US, where scientists are searching for a cure against FIV – the virus that causes AIDS in cats.

PHOSPHORESCENCE MAKES THE OCEAN LIGHT UP

The phosphorescence phenomenon is caused by small plankton known as dinoflagellates. The creatures unite in surface water, often in near-shore areas, and if there is motion in the water, the creatures light up. The light show is probably a defence mechanism to confuse enemies.

TERRIFYING TOADFISH USES LIGHT AS BAIT

In the deep sea, where there is no sunlight, light is an efficient tool to attract mates, deceive enemies, or make prey come closer. The deep sea toadfish waves a “fishing rod” equipped with a bright organ in front of it to attract prey. The largest toadfish species grow up to 120 cm long.
