His wise friend Mr. Owl has just the advice: treat otters the way you’d like to be treated!

Sea Otters (National Geographic Kids Readers, Level 1)
Sea Otters | Laura Marsh / National Geographic Kids | Ages 5–8 | Paperback Level 1 Reader
If your child is just starting to read independently — or loves the feel of being a proper wildlife researcher — the National Geographic Kids Readers series is hard to beat, and this sea otters edition is one of the best in the range. With gorgeous real photography on every page, simple but information-rich text, and the reliable National Geographic Kids stamp of quality, it covers everything from how sea otters use their paws like hands, to how a mother otter carries her pup on her chest while she floats on her back.
It’s a Level 1 reader, perfectly calibrated for newly independent readers aged 5–8. Short sentences, familiar vocabulary, and brilliant photographs make this an ideal bridge between picture books and longer nonfiction — and kids tend to reread it again and again just for the pictures.
Peek, Otter! (National Geographic Kids Pre-Reader)
Peek, Otter! | Shira Evans / National Geographic Kids | Ages 3–5 | Paperback Pre-Reader
Got a younger otter enthusiast at home? This is the one. Peek, Otter! is a Pre-Reader from National Geographic Kids — designed for children who aren’t yet reading independently, making it a gorgeous book to share together. It introduces river otters through simple, playful text and stunning real photographs, with vocabulary-building features that help little ones learn new words in context.
Short, punchy, and absolutely adorable — it’s the kind of book toddlers and preschoolers want to look at over and over again. If you want to spark a love of wildlife and reading at the same time, this is a brilliant starting point. Pairs perfectly with the Level 1 Sea Otters reader above as kids grow.
Otter: I Love Books! (My First I Can Read)
Otter: I Love Books! | Sam Garton | Ages 4–8 | Paperback Early Reader
Sam Garton’s irresistible Otter series has built up a loyal following among early readers — and I Love Books! is the perfect entry point. Otter discovers an absolute passion for reading (honestly, same), and the results are as funny and sweet as you’d expect from this beloved character. Carefully crafted with basic language, word repetition, and sight words, it’s ideal for children who are beginning to read on their own but still love the warmth and humour of a great picture book.
Fans of Llama Llama tend to adore Otter immediately. There are several books in the series — Otter Goes to School, Otter Loves Halloween, and more — so once your child falls for this cheerful little character, you’ve got a wonderful reading journey ahead.
If You Take Away the Otter
If You Take Away the Otter | Susannah Buhrman-Deever, illustrated by Matthew Trueman | Ages 5–8 | Hardcover Picture Book
This is one of those genuinely special books that sneaks in some serious science while being completely beautiful to look at. Following a “what if?” structure, it takes readers through the extraordinary ripple effects that would occur if sea otters disappeared from the ocean — revealing, in the most child-friendly way possible, exactly what a keystone species is and why one animal can change an entire ecosystem.
Matthew Trueman’s stunning mixed-media illustrations make this a visual treat, and the science is impeccably researched. It’s been recognised by the ALSC (Association for Library Service to Children) and is a standout pick for curious kids aged 5–8 who love understanding how the natural world connects. A wonderful classroom book for introducing ecology and conservation.
Pup the Sea Otter
Pup the Sea Otter | Jonathan London, illustrated by Sean London | Ages 4–8 | Paperback Picture Book
A tender, beautifully told story that follows a baby sea otter — Pup — through his first days of life, tucked safely against his mother’s chest as they drift in the kelp forest. Written in spare, lyrical prose by Jonathan London, with luminous illustrations from his son Sean, it captures the magic of the sea otter world in a way that feels genuinely moving.
Pup the Sea Otter is a multiple award-winner: it took the 2017 National Outdoor Book Award, the 2017 National Science Teacher’s Association Outstanding Children’s Trade Book Award, and the 2018 ILA/CBC Children’s Choice Award — and all three make perfect sense once you’ve read it. It’s the otter book for families who want a story to curl up with, not just facts. Have tissues ready.
