In "Island of the Blue Dolphins" by Scott O'Dell, the blue dolphins hold a special significance for the protagonist. They symbolize a connection to her home and represent the longing for companionship and familiarity. As she navigates the challenges of isolation, the dolphins serve as a reminder of her past and the life she once knew. Their presence evokes feelings of nostalgia and hope, highlighting the deep bond between humans and nature.

The quote reflects the powerful emotional ties that the character feels with these creatures. They are not merely animals in her surroundings but embody her memories and a sense of belonging. The dolphins' beauty and grace captivate her, reminding her of the importance of home and the connections that define her existence. This relationship with the dolphins illustrates a central theme of the story: the struggle for survival and the enduring ties to one’s roots.
