Pearly mussels: One of North America's natural jewels is disappearing
...n their choice of host, some mussels use elaborate lures to attract the correct fish species. In adulthood, pearly mussels act as filter feeders, eating plankton and other small particles of food suspended in the water. Long-lived animals, most species live for decades. Currently, little is known about ei...Using science to restore habitat for declining species

The Wnt family of proteins carry signals from cell to cell, regulating the interactions between cells during many development processes.

...till set out in small skiffs (called pangas), drop lures overboard and pull up their catch by hand. During fishing season, as many as 300 pangas will go out in the evening and return the same night with up to a ton of squid per boat.

...se color to attract mates. In this case, the color lures prey to the web. Perhaps the color itself may look like flowers to the insects that eventually become entrapped in the web," he says.
