Shelled Meerslug

The Shelled Meerslug is a saltwater invertebrate found in Pikmin Z. It is similar to the Coral Meerslug, with the exception of keeping its large shell.

Biology
The Shelled Meerslug has evolved to have a large shell, which it uses for protection against predators. However, it holds little threat to Pikmin or leaders besides eating them.

Piklopedia entry

 * "It may appear like a relative to the Coral Meerslug, but it is in fact a completely different species. This is evident due to its hardened shell, of which it retained from its life on land."

Strategy
It is invincible if it hides in its shell. Attack it from the front before it can retreat.
