I watched a few episodes a few years ago of this mini series on the Sci-Fi channel about a boy that finds an egg or something. It hatches and grows into this cute green sea creature. The boy gets hurt and the sea creature goes to the hospital and tried to lick his wounds to heal him and the doctors shoot it. as the creature is dieing, the boy gets worse and almost dies himself. Also, there is a HUGE creature that swallows a large boat making a man and woman stranded in the water in the creatures eggs. These creatures have electricity powers from what I remember... And they also attack people. Does anyone know what this show was is???
That sounds like the series Surface, which ran for about 15 episodes on NBC back in 2005, before being rerun on Scifi.

Shadow is correct.
What you saw was the re-broadcast of Surface.
