Which male animals have pouches?

A Seahorse has a brood pouch, in which the female deposits the eggs.

There is a "marsupial bird" called a Sungrebe, found in South America. Immediately after the young chicks hatch, the male places them in pouches under his wings, and leaves the nest, presumably tending the chicks while keeping them under his wings.

The Emperor penguin incubates the female's egg in a brood pouch.

The extinct Thylacine of Australia, or Tasmanian Tiger, had a pouch, but not for the purpose of carrying the joeys - it was for protecting its male reproductive parts while it ran through dense underbrush.
