WTF!!!! OMG is this a reef spider?????!!!!!!!!!

[Delphinus]

There are such things as underwater species of spiders however they look *nothing* like terrestrial spiders. This is a land spider that wound up on the floating mat of chaeto.

I second the nomination to set it free outside and let it do its job of catching and eating the the more annoying bugs like skeeters and flies and aphids and/or whatever else they eat.
