Which is the only ‘male’ species that gets pregnant, gives birth & takes care of ‘their’ well being ?

In sea horses, the males become pregnant. Their mating involves the female inserting her oviduct into the male’s brooding pouch. She does this several times for short intervals to avoid exhaustion. In between the female rests while the male contorts himself to try to get the eggs in place in his brood pouch. After completion the male moves away and attaches himself by his tail to a nearby plant. The female moves away and waits for her oviduct to recede. The oviduct usually recedes within a few hours. The eggs are fertilized and hatch in the male’s pouch (Graham 1939). The size of the sea horse brood varies within sea horse species. Some species’ broods are as large as 200 (Graham 1939) while others are as small as 8 (Breder 1940).

I do not think the male sea horse actually gets prego, but they do rear the young an dact as mom and dad at times.
