Both are mammals, so both have mammary glands, and hair on their skin, and they have 7 cervical vertebrae as humans do.

They are touted to be one of the only 3 animals that mate for pleasure (humans, dolphins, bonobos), and socially with many partners as many humans do. They also mate face to face unlike other animals. Dolphins do give birth to live young, and as mammals, they nurse their young with breast milk.

They have very high communication skills amongst themselves. They are very social and prefer to live in pods rather than alone. Females will create a communal/ family creche for the young, so that others may go to hunt and feed. They show emotions of happines and sadness. They mourn the death of a member of the pod, especially an offspring. They also display working in teams to achieve a common goal. When hunting, they create tight balls of sardines by circling and herding them, and then diving straight through them to feed. Pods are very protective of each other and sometimes show compassion, and may adopt a young out of another pod if it has been left behind or lost its mother.

Additionally, they have mirror neurons, being able to pass the mirror test and detect themselves in a mirror. Mirror neurons may also indicate empathy.

In short, they display more "human" emotions and behaviors than any other non-primate mammal.
