Don't Mess with Me
The role of venoms in nature … and in human medicine Why are toxins so advantageous to their possessors as to evolve over and over again? What is it about watery environments that favors so many venomous creatures? Marine biologist Paul Erickson explores these and other questions with astounding images from Andrew Martinez and other top underwater photographers. GREAT for teaching STEM Marine Biology Scorpions and brown recluse spiders are fine as far as they go, but if you want daily contact with venomous creatures, the ocean is the place to be. Blue-ringed octopi, stony corals, sea jellies, stonefish, lionfish, poison-fanged blennies, stingrays, cone snails, blind remipedes, fire urchins—you can choose your poison in the ocean. Venoms are often but not always defensive weapons. The banded sea krait, an aquatic snake, wriggles into undersea caves to prey on vicious moray eels, killing them with one of the world’s most deadly neurotoxins, which it injects through fangs that resemble hypodermic needles.
One Iguana, Two Iguanas
KIRKUS STARRED REVIEW 2020 Outstanding Science Trade List A Junior Library Guild Selection Natural selection and speciation are all but ignored in children’s nonfiction. To help address this glaring deficiency, award-winning children’s science writer Sneed Collard traveled to the Galapagos Islands to see for himself, where Charles Darwin saw, how new species form. The result is this fascinating story of two species of iguana, one land-based and one marine, both of which developed from a single ancestor that reached the islands millions of years ago. The animals evolved in different directions while living within sight of one another. How is that possible? Collard uses the iguanas to explore Charles Darwin’s great discovery. F&P Level V
