L. oceanica is oval, twice as long as broad and may reach up to 30 mm in length, making it the largest oniscid isopod . Its colour may vary from grey to olive-green, and it has large compound eyes and long antennae, ⅔ as long as its body .
L. oceanica is found in temperate waters from Norway to the Mediterranean Sea and from Cape Cod north to Maine . 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 . It is a nocturnal omnivore, eating many kinds of seaweed, diatoms and debris, with a particular fondness for bladder wrack (Fucus vesiculosus) .
L. oceanica individuals live for 2½–3 years and usually breed only once .
