Shrew Caravan

Description:  Shrews spend most of their lives underground and so have very poor eyesight, relying primarily on their highly developed senses of smell and hearing. When a mother shrew wants to move all of her offspring from one location to another (particularly above ground) ear shrew will hold onto the shew in front forming a long caravan. This could be used as a phenomenon to introduce animal behaviors, especially those of a parent to ensure the safety of their offspring.
