Ligia oceanica, the sea slater, common sea slater or sea roach, is a littoral woodlouse.

L. oceanica is oval, twice as long as broad and may reach up to 30 millimetres (1.2 in) in length, making it one of the largest oniscid isopods.[2] Its colour may vary from grey to olive-green, and it has large compound eyes and long antennae, ⅔ as long as its body.[3]

L. oceanica is found in temperate waters from Norway to the Mediterranean Sea,[4] and from Cape Cod north to Maine.[5] It is a common species, occurring wherever the substrate of the littoral zone is rocky, and is especially common in crevices and rock pools and under stones.[3] It is a nocturnal omnivore,[6] eating many kinds of seaweed, diatoms [3] and debris, with a particular fondness for bladder wrack (Fucus vesiculosus).[2]

L. oceanica individuals live for 2​1⁄2–3 years and usually breed only once.[6]
