Halimeda

/ˌhæləˈmeɪdə/ noun

Definition

A genus of green algae found in tropical and subtropical seas, forming distinctive segmented, coin-shaped fronds.

Etymology

From Greek 'hals' (salt/sea) combined with 'melos' (limb), referring to the segmented, limb-like structure of these seaweeds. Named scientifically in the 18th century by taxonomists studying marine flora.

Kelly Says

Halimeda algae are nature's chain-mail armor—their segmented, coin-like segments can break apart and tumble along the seafloor, eventually contributing to tropical sand deposits, meaning you might be walking on ancient Halimeda when you visit a Caribbean beach.
