BUT a jellyfish has 24 eyes! Strategically allocated at 4 corners of its bell.
It visually responds to different colours.
THE VISUAL EXPERIMENT
THE VISUAL EXPERIMENT
When white pipes were placed standing in a tank, jellyfish just swim directly into it, just like some blinded creature.
However, when it was changed to black pipes, it swam around it in some figure of eight motion.

It responded even more drastically with red pipes, swimming really far away from the pipes. It was apparent that the jellyfish was avoiding the red pipes.
Really amazing, something which the scientists has been trying to answer.

IT STINGS!
AND they really kill!
AND they really kill!
[No wonder mr crocodile man was fatally killed by it. =S] Muahahaha... Just realised I mistaken a stingray for a jellyfish =S Thx KS for highlighting it=P
Similar to snakes and scorpions, jellyfishes release powerful venom. Each venom specifically targets a particular area. For snakes, it attacks the skin cells while for the scorpions, it attacks the nervous system.
Astonishingly, for the jellyfishes, the venom does it all! =S No wonder it is the deadliest venom in the animal kingdom!
While most of them are generally not deadly, the box jellyfish and the Irukandji jellyfish are considered fatal.
Interestingly, sea turtles are unaffected by box jellyfish and eat them regularly.

A mature Irukandji jellyfish is only approximately around the size of an adult's thumb.
Irukandji syndrome hits victims with severe headaches, uncontrollable muscular movements, nausea, hypertension, chest and muscle pains.
Apparently, the National Geographic programme on Jellyfish Invasion is highlighting the issue on the blooming population and the increasing presence in the seas and oceans.
Hopefully we can coexist with them. Otherwise, dramatic ecological imbalance in the marine ecosystem may arise.

Let's love the nature more and not over exploit it. I believe we are part of the ecosystem, what we do will eventually impact us still.
