When animals attack #1: Blue Jellyfish


Hopefully the first of a very short series picturing the potentially hazzardous wildlife I've spotted! Firstly introducing the Blue Bottle...
The blue bottle feeds on small fish and other small ocean creatures. They envelope their prey with their tentacles, where a poison is released thus paralysing its prey before being consumed. The tentacles adhere extremely well to their prey. If a tentacle is put under the microscope you will see that it looks like a long string of barbed hooks, which explains the ability of the tentacle to attach.
If a tentacle attaches itself to a human, it releases a poison (through the use of nematocysts), and if you continue to rub the skin after the tentacle has been removed more poison or venom will be released. If you are stung, it is best to wash the area without touching. A cold pack should be used to relieve the pain. If stung, please consult a doctor immediately. No fatalities have ever been reported within Australia or New Zealand from the sting of a blue bottle.

Nice photo mate. We have blue bottles over here too, but they usually buzz around and walk poo into your food. I'll bet you're missing them already!!
