The Mysterious World of Sea Slugs
Sea slugs—the little-known beauties of Tatsukushi Bay
Sea slugs are invertebrates that are usually found at the bottom of the ocean. About 1,400 types of sea slugs live in the waters around Japan, and 384 of these species are known to inhabit Tatsukushi Bay.
Sea slugs are a type of shellfish
We may look much like sea cucumbers, but are actually more closely related to the snail-like conch, which lives in a spiral shell.
They can’t see very well
We have very limited vision and can only make out whether something is light or dark.
They come in all sizes
We’re a diverse bunch, ranging from 1 millimeter to over 50 centimeters in size.
They are also called “sea cows”
In Japanese, we’re called umiushi (“sea cows”) because our feelers resemble cattle horns.
