The range of this species is from Alaska to Mexico. The waters are rich in nutrients such as plankton and bacteria. Estuaries also rank among the environments most affected by humans. That said, let’s look at several examples of each category. Birds are very common in estuaries because of the abundance of fish, worms, crabs and clams. The Pacific Spiny Lumpsucker spends its time foraging for food on the bottom of estuary waters, eating worms and mollusks.
