Dr.Frank lyko, a biologist at the German Cancer Research Center, studies the six-inch-long marbled crayfish. Finding animals is easy: Dr. lyko can buy the crayfish at pet stores in Germany, or he can head over to a river or to a nearby lake to catch crayfish to study and experiment on.
Sometimes he waits till dark, switch on headlamps, and wander into the shallows. The marbled crayfish will emerge from hiding and begin swarming around his ankles.
“It’s extremely impressive,” said Dr. lyko. “Three of us once caught 150 animals within one hour, just with our hands.”
Over the past five years, Dr. Lyko and his colleagues have sequenced the genomes of marbled crayfish. In a study published on Monday, the researchers demonstrate that the
