Widelife in Panama with a snake and a spider

If they told you there aren't so many snakes, spiders, insects or dangerous animals within a region you go to in tropics - they lied. This is what happens in 2h here.
Is it dangerous in Panama? I don't think so, but better don't touch and check is it venomous.
