Bloodsucking Lampreys [PDF ebook] 

Lampreys aren’t just freaky because of their funnel-shaped mouth or many species’ appetite for blood. They’re an invasive species slowly entering North American waters and causing harm to native species there. Readers learn about the problems invasive species cause as well as details about the parasitic relationships lampreys engage in with other fish. The gross truth about how they suck blood will fascinate readers as they also learn about lampreys’ life cycle, habitat, and more. Up close photographs of lampreys in action are surely as close as readers will want to get to this real-life vampire.
