A slug is like a snail but it has no shell. It has four tentacles on its face—two that can see and two that can smell. Many slugs actually do have shells, but inside their bodies. Sea slugs live in the sea, but land slugs also need a lot of water, so they are more active when it is wet.
ナメクジは殻のないカタツムリみたいなものです。顔に四つの触手があって、ふたつは明かりが見える触手でふたつは匂いが嗅げる触手です。多くのナメクジは実は殻を持っていますが体の中にあります。海に住むナメクジ以外でも水をたくさん必要としますので、湿ったところでより活躍します。
