Glaucus Atlanticus: what.....

What is This:

o my God, i want to share a pic. a really very strange creature. I got it from Google labeled for reuse images and whoa my mouth forgot to close. no no no do not touch it if you love to see it You might get sting and may be injected with a painful venom. It is Glaucus atlanticus.
May be a large number of people know it but this world has millions of people who haven't seen it.

Its name is really very strange Glaucus Atlanticus but for your ease you may call it
sea swallow,
blue angel,
blue glaucus,
blue dragon,
blue sea slug
and blue ocean slug. It wont mind and if it minds then it will show its anger by just a sting. okay just kidding......
It can be found in East and South Coast of South African seas, European waters and some other places of Australian waters.
Its life span is just one year but during this short span they just prove to be a
sea terrorist.
Okay kidding... they love to float upside down showing their bright lovely blue color combination to catch their prey and to scare their enemies too. This beautiful bright blue combination of blues is their abdomen. Yeah very small and innocent but they prey bigger in size sea creatures. they are just 1.5 inches in size but o my God they are very rude and cruel.
