Sea lions

I see what my mother calls a boat,
I dive down back under the water silently,
The water is not cold thanks to my blubber and short fur.
I swim back to the shore and use my call,
There, a reply, I go again. Mothers at the shore I use my long fore flippers to bound up to her.

This was my life before they took her. 
We were hunting for dinner.
I kept swimming around her,
We spotted some Penguins chasing some Krill,
I was closing in on a Penguin.
When out of the blue a net came to Kill,
A net went for mother closing in.
I tried to warn her, CREAK… to late
They hauled her up leaving me alone and Motherless.
