About The Book

Dive in and explore the wonders of the ocean and its inhabitants in this lyrical, fact-filled ode to the sea! This beautifully illustrated picture book features extensive nonfiction backmatter for further exploration.

We are young. The sea is old. The sea has secrets to unfold. The sea knows.

In this playful, rhyming celebration of the marine world, readers can explore all of the wondrous things the sea knows. It knows huge whales and small krill; it knows short crabs and tall giant kelp; it knows brightly colored starfish in shallow pools; and in the inky depths it knows the alluring jewel of an anglerfish’s glowing lure.

Discover all of the strange and magnificent underwater creatures in this accessible tribute to the power and mystery of the ocean.

About The Authors


Alice B. McGinty often stops to look, listen, and wonder, which has led her to write over fifty fiction and nonfiction children’s books that capture the truths and mysteries of life and nature. Her books include Pancakes to Parathas: Breakfast Around the WorldThe Girl Who Named Pluto: The Story of Venetia BurneyThe Sea Knows, and the award-winning picture book biography, Gandhi: A March to the Sea. Alice lives in Champaign, Illinois, and spends her time seeking wonders, always looking for inspiration for her next books.


Alan B. Havis has been wordsmithing as an attorney for thirty-four years and has been creating in a variety of art forms for as long as he can remember. One day, while he and Alice were walking on the beach in Negril, Jamaica, they began to talk about how awe inspiring the sea was and how much we don't know about the sea’s secrets. Alan responded, “Ah, but the sea knows,” which formed the genesis of The Sea Knows, which is his debut book. Applying his writing skills and creative nature, Alan enjoyed combining his talents with Alice’s and creating The Sea Knows. Alan lives in a suburb of Detroit, Michigan, and now spends his time dreaming and writing.

Take a tour of the underwater world in this visual introduction to the sea. Readers will be swept away by a colorful school of fish and will have a front-row seat as a blue whale scoops up a mouthful of krill. McGinty introduces a variety of ecosystems and plant life, as well as many fascinating creatures. The most effective feature of this book is the digital illustrations that showcase the variety and complexity of ocean life. Through careful use of color, the author and illustrator spotlight a world that sometimes appears peaceful and small, and at other times seems volatile and untamed. The pages will be turned with ease, following the rhythm of tightly crafted couplets....A solid selection for nature/science-themed storytime or as a springboard for future investigation.–Louie Lauer, Jefferson Elementary School, Fargo, ND
