A midnight stroll
Photo and caption by Matthew Farrugia
This hermit crab was photographed during a night dive using a snoot. Despite the common name, hermit crabs are related more closely to lobsters than to crabs. They lack a hard carapace, and adopt the empty shells of gastropod molluscs (such as whelks), carrying them around and swapping them for a larger shell as they grow.
