Blue Crab Shell (Whole)

In the wild, hermit crabs forage on crab shells along the shoreline — now they can do the same right in the tank. 🦀

A whole blue crab shell is a mineral-rich source of calcium and magnesium — two nutrients hermies need for strong exoskeletons and healthy molts. It also gives them a natural way to stay busy — investigating, climbing on, and working at the shell just like they'd find on the beach.

Orders $35+ ship free. Orders under $35 ship flat $4.99 — no surprises at checkout. We cover any extra shipping cost so you can focus on spoiling your hermies. 🦀

ABOUT THIS ITEM
One (1) whole blue crab shell. Fully traceable, sourced, cleaned, and packaged in the USA — no chemicals, no additives, no artificial treatments.

KEY BENEFITS
• Natural source of calcium & magnesium
• Supports exoskeleton strength & healthy molting cycles
• Encourages natural enrichment behaviors
• Long-lasting — won't break down like other enrichment items

HOW TO USE
Place the shell directly into your crabitat. Hermit crabs will scrape, nibble, and forage on the shell as needed. Leave it available at all times as part of a varied, mineral-rich environment.

SIZE
Approximately 6–7 inches long and 4 inches wide.

Because these are natural blue crab shells, every shell is unique and will vary slightly in shape, color, texture, and markings.

STORAGE & SAFETY
Store unused shells in a cool, dry place away from direct sunlight. If your crabitat runs humid, some natural weathering over time is normal — this doesn't affect safety.

NOT FOR HUMAN CONSUMPTION.
