CHAPTER 1
BENEATH THE SURFACE
Janet Mann & Andrew Read
How and why do we study cetaceans? This chapter looks at the history of human association with cetaceans from whaling to research and monitoring in the wild and in captivity and the challenges ahead.
CHAPTER 2
THE CETACEAN BRAIN
Camilla Butti & Patrick Hof
By studying mammals’ brains and comparing those of odontocetes and mysticetes scientists demonstrate that, in terms of intelligence, size isn’t everything. This chapter considers the relationship between brain and body mass and how scientists determine what it means to have a big brain.
CHAPTER 3
COGNITION
Heidi E. Harley
Humans make sense of their surroundings primarily by sight, a perspective that can skew understanding of cetacean cognition. This chapter adopts the cetacean perception of their aquatic world—using multiple senses, including sound and echolocation.
CHAPTER 4
CETACEAN COMMUNICATION
Laela Sayigh & Vincent Janik
How do cetaceans communicate through water? Studies of whale song and dolphin whistles demonstrate the types of communication and consider call function, social recognition, and communication networks.
CHAPTER 5
QUINTESSENTIALLY SOCIAL CETACEANS
Janet Mann
Social bonds bind cetaceans throughout their lifetimes. Long-term studies have been crucial in revealing remarkably complex communities in which relationships are based on affiliation, aggression, kinship, communal care, protection, mating strategies, and extended networks.
CHAPTER 6
DEEP CULTURE
Hal Whitehead & Luke Rendell
We may assume culture to be a uniquely human condition, but cetaceans display considerable cultural diversity. This chapter assesses behavior, communication, social dynamics, migration, cooperative hunting, and learned foraging techniques.
CHAPTER 7
CETACEAN TOOL USE
Eric Patterson & Janet Mann
Like primates and birds, cetaceans use tools for different tasks and different reasons: sticks, shells, and sponges become tools for attraction, display, and foraging purposes.
CHAPTER 8
US & THEM
Andrew Read
From our first encounters with whales as game to attempts to save species from extinction, this chapter looks at how humans and cetaceans coexist. Hunting, fishing, pollution, and sonic disturbance are among the threats whales and dolphins face from human activity.
