I think it could be interesting to encode messages into the DNA of an ant, for example, then mail the ant somewhere so that the receiver can sequence the DNA and decode the message
That's been done, though it's much harder to do on living things because attempting to change the DNA of something that's still alive opens up a can of worms that makes it not worth it. They've once proved you can encode the whole of Wikipedia on a few strands of hair.

Damn. Wikipedia pictures too or just text?
Probably the read-only version.
