[DC] Can Aquaman communicate with all creatures in the animal kingdom, or just the aquatic one?

I know this might seem like a stupid question, considering his name, so bear with me.

I know Aquaman can talk to all manner of sea life.  From fish, to crabs, to plankton and everything in between. But he can also talk to mammals like dolphin and whales.  


Is he limited to creatures that claim water as their habitat?  What about hippos?  Or crocodiles?   Turtles?

What about beavers or otters who are technically land creatures, but make their home on the water?


Can he talk to sea birds?  Penguins and Ospreys?


I feel like there’s a bunch of grey area between some of these animals.

The closer an animal is to being an ocean creature the better he can communicate with it.  He at one point gave a White Martian a seizure by focusing his powers and they are pretty far removed from being from the ocean.
