What are some examples of animal mimicry?

Animals use mimicry to hide from predators or blend into their surroundings. Many creatures, such as the Cranchia squid, change color to match their environment, while marine worms build chimneys covered with bits of coral and weed to resemble plants^[1]. Sea anemones and trapdoor spiders also decorate their homes or bodies with shells, moss, and plants to remain hidden^[1].

In the Sargasso Sea, mollusks and fish like the antennarius have evolved colors and shapes that perfectly mimic the gulf weed, making them nearly invisible^[1]. Some crabs even actively decorate their shells with living weed to disappear among rocks^[1].
