I am ,they are.

My dad is a grizzly.

Scaring any intruders,

 that are interfering with the family.

He is the protector.

My mum is a lion.

Bellowing and  keeping us

 warm and alive.

She is the boss.

My sister is a sloth,

Hanging from branches

Keeping cool and calm.

She is peace.

I am a monkey,

Swinging from tree to tree,

Being cheeky and funny

,exploring everywhere.

I am the joker.
