An answer to the titular question—and then some.
“When it is time for these animals to rest / where do they go to sleep their best?” The authors offer very brief bits of information on various sea creatures, among them stingrays, walruses, clownfish, bottlenose dolphins, sea otters, and great white sharks. In addition to sleeping habits, we also learn other facts, such as what seahorses eat and how the parrotfish got its name. The book opens with images of racially diverse children playing at the beach; it closes with a child cuddled up in bed. A brief authors’ note stresses the importance of sleep for children. Contradicting the title, not all creatures here are diurnal. The statement that “the octopus can sleep by day or night” is misleading, given that most species are nocturnal. Many fascinating facts are overlooked; we learn that sea turtles have hard shells and live to be 80 years old and that they rest under rocks or coral but not that they hold their breath for hours while sleeping. Though watercolor illustrations in various shades of blue offer sweetly expressive depictions of the animals, the verse format adds little to the text; uncertain meter foreshadows weak rhythm and rhyme.
Visually attractive but doesn’t dive very deep.
