Definition
A 'sand flea' is a common name for small, hopping crustaceans belonging to the family Orchestiidae, particularly those in the genus Orchestia. These creatures live on sandy beaches and are known for their jumping ability. Think of them as tiny, hopping critters of the beach ποΈ. They feed on decaying organic matter, contributing to decomposition. They are usually more active at night or during cooler parts of the day. Despite the name, they are not insects and do not bite humans π .
