As low tide comes and the salty water slips away, a sleek little horseshoe crab learns how taking critters and creatures for a ride could save his life!

The Bumpy, Lumpy Horseshoe Crab is a horseshoe crab adventure with a happy ending. This picture book has a whimsical, rhyming style, and portrays horseshoe crabs exhibiting behaviors that they commonly use in real life. It's the perfect choice for a family read-aloud for children 3-10 years old. It also is a great tool for teachers who are studying marine life, tidepools, or coastal sea animals. The fun, colorful, simply drawn illustrations are expressive, and bring each sea creature to life. Although two horseshoe crabs are the central characters, periwinkles, limpets, barnacles, and green and Jonah crabs are also portrayed in the story. At the end of the story, there are pages containing information about horseshoe crabs and other sea animals that appear in the story.

The Bumpy, Lumpy Horseshoe Crab is the first book in Petrie's sea animal series. Did You Make the Hole in the Shell in the Sea? and Something's Tugging on My Claw! are two award winning books that complete Petrie's three book rhythmic, rhyming, and colorful series.
