It is called seahorse Farafina.
The only animal that I know of who can impregnate itself - male/female fertelisation  - could not resist the additional info

Page: A boy becoming a young man. He is starting to deal with different or new emotions, those he has never had before. Becoming more mature.
Knight: Bearer of good news. He is on his way to give his parents the news of his engagement to the love of his life.
Queen: I can't stop thinking that something isn't right. My son is engaged, but yet. Mybe I'm too emotional. I need to think awhile and get my emotions under control. I am such a worry wart.
King: So, my son is engaged. It is time to give him some fatherly advice about married life. Or just listen to him and let him talk about his hopes and fears or any concerns he might have.

Can you see a common theme?

Everyone seems to be consumed by their cup.  I sense distraction, relaxation, dreamer, a unhurried peacefulness, calm.

This family appears to be consumed in thought of the beauty set before them.  So consumed that other things don't come through.  Except the King.  He has his beauty but is not staring at it.  He holds it, appreciates it, but does not allow it to consume him.

Peacefulness, dreamers, water all around.  emotional, loving, compassion
