Curious About Crocodiles
Flying Eye Books
Book seven of Owen Davey’s splendid series explores members of the weird and wonderful Crocodilia order. The order includes crocodiles as well as alligators, gharials and caimans, all of which are strong, armoured reptiles with four short legs, powerful jaws – beware! long, flattened snouts and long tails. Each kind spends some time on land and some in the water.
After his general introduction, Owen looks first at design using the Orinoco crocodile to which he takes us right close up and decidedly uncomfortable. I was more than a tad jealous to read that when one of these creatures loses a tooth, another one replaces it and a single croc. can go through as many as 4000 teeth in its lifetime.
Dinosaur enthusiasts in particular will be interested to learn that millions of years ago crocodiles and dinosaurs shared the earth.
The other dozen topics, each given a double-spread, take a look at movement – sometimes crocodilians walk low to the ground but more frequently adopt a ‘high walk’ and some of the smaller species can break into a run, while others might climb trees. Most although excellent underwater swimmers, tend to stick mainly at surface level.
Did you know that a crocodile’s gender is determined by the temperature of the nest at a crucial point in the development of the egg with high and low temperatures tending to result in female babies, though due to varying layers of a nest having different temperatures, it’s likely that a clutch will have hatchlings of both sexes? First of course, a male has to attract a mate and to do so, some blow bubbles and produce a water dance with vibrating bodies and water droplets ‘that dance around them’.
As with his previous guides, Owen has packed this with a wealth of engrossing biological information as well as some mythology; and last but definitely not least, a look at conservation including some things readers can do to help preserve both the creatures and themselves.
Truly something to chomp on and bound to scale up the interest of budding young zoologists.
