Tidepool Tim says,  “Lacy crust is one of the prettiest organisms you will see in tidepools, in kelp beds, or even washed up on the shores. This animal grows as a colony with new growth emerging at the lateral edges of the white colony. Since some kelp plants grow for many years, sometimes this bryozoan can be 12" in diameter. I have seen thousands of these over the years and still, they command my attention every time I see a new one.”
