dolphins ,bats, and submarines all have echo location
Bats and Dolphins both use sound to navigate.
I don't think dolphins and bats talk to each other much. Bats live on land and dolphins live out at sea.
Bats, dolphins, Whales, shrews, flying squirrels use echolocation.
Even fairly large bats have brains the size of maybe almonds. We don't really know how "intelligent" dolphins are, but they're probably a lot smarter than bats.

by using echolocation
Bats and toothed whales (dolphins, porpoises, killer whales, sperm whales, and river dolphins).
Bats, dolphins, dogs.
Dolphins and bats both produce very high pitched sounds and have excellent hearing. The sounds bounce off of objects, creating a very faint echo, which is effected by the objects in the surrounding environment. Dolphins and bats hear this echo, and their brains formulate a mental image of where objects are, there shapes, their sizes, etc. Both dolphins and bats use this for navigation and to detect prey.
