What is the meaning of shaggy jaws from poem sea?

In the poem "The Sea" by Henry Wadsworth Longfellow, the phrase "shaggy jaws" refers to the jagged and rocky edges of the sea cliffs that are pounded by the waves. The term "shaggy" evokes the image of something rough, unkempt, and covered in hair, while "jaws" suggests a devouring or menacing quality. Together, these words create a vivid picture of the wild and untamed nature of the sea, with its sharp and dangerous coastline.
