Most decorator crabs belong to one of eight families in the superfamily Majoidea, commonly referred to as spider crabs. About 75 percent of the group’s more than 1,100 global species mask their presence by wearing disguises made from living organisms scissored from the landscape. They commonly hijack seaweeds, sponges, tunicates, bryozoans and hydroids. The crabs manipulate the purloined pieces of attire with their mouths before attaching them to one of the many fishhook-shaped bristles arranged in rows on the carapace, rostrum, walking legs and claw arms, depending on the species.

Ada banyak standar dan panduan untuk batas aman, termasuk hasil berbagai studi kesehatan dan keselamatan kerja tentang efek paparan yang lama. Untuk menyelam, situasinya berbeda. Jadi, berapa batas aman untuk penyelaman rekreasi dengan paparan yang jauh lebih singkat daripada penyelam angkatan laut? Khususnya, berapa batas aman untuk karbon dioksida (CO2), kontaminan potensial yang paling melimpah?
