I encountered with this insect on the wet floor in Sri Lanka. Is it dangerous?

  • $\begingroup$ I see you edited your question, incorporating the cerci of my answer, to address the fact that the antennae was not a antennae... but now the question's title is a bit contradictory! $\endgroup$

  • $\begingroup$ Yes I did it with intention to help someone who will search with the real name of that thing. (At first I didn't know it's called cerci before your answer.) I understand now its not going well with your answer however. $\endgroup$

Actually, the antennae of that insect are not scary at all!

In your image, the antennae are pointing down; those forceps-like structures pointing up are part of abdomen, and are called cerci.

That insect (probably a male) is an earwig, from the Order Dermaptera. In the image below, the antennae are at the left, while the abdomen and the cerci are at the right:

Narrowing down the the Genus of your specimen is more complicated, but here is a list of earwigs from Sri Lanka: https://en.wikipedia.org/wiki/List_of_Dermapterans_of_Sri_Lanka

Regarding the danger: earwigs are not dangerous. The cerci may be scary, but they normally are not capable of hurting a human. Also (and I hope you don't believe urban legends), they do not lay eggs in human ears: http://www.snopes.com/horrors/insects/bugear.asp
