<About the Author>
The animal on the cover of Practical Machine Learning with H2O is a crayfish, a small lobster-like crustacean found in freshwater habitats throughout the world. Alternate names include crawfish, crawdads, and mudbugs, depending on the region.
There are over 500 species of crayfish, over half of which occur in North America. There is great variation in size, shape, and color across species. Crayfish are typically 3 to 4 inches in North America, while certain species in Australia grow to be a staggering 15 inches and can weigh as much as 8 pounds.
Like crabs and other crustaceans, crayfish shed their hard outer shells periodically, eating them to recoup calcium. They are nocturnal creatures, possessing keen eyesight as well as the ability to move their eyes in different directions at once.
Crayfish have eight pairs of legs, four of which are used for walking. The other legs are used for swimming backward, a maneuver that allows the crayfish to dart quickly through the water. Lost limbs can be regenerated, a capability that comes in handy during the competitive (and often aggressive) mating season.
Crayfish are opportunistic omnivores who consume almost anything, including plants, clams, snails, insects, and dead organic matter. Their own predators include fish (they are widely regarded as a tackle box staple), otters, birds, and humans. More than 100 million pounds of crawfish are produced each year in Louisiana, where it was adopted as the state's official crustacean in 1983.
Many of the animals on O'Reilly covers are endangered; all of them are important to the world. To learn more about how you can help, go to animals.oreilly.com .
