Land Crab Species & Morph Identifier

What is the Land Crab Species & Morph Identifier?

The Land Crab Species & Morph Identifier identifies likely species or morph of land crabs from color and pattern cues. Knowing what you're working with shapes everything from diet and housing to expected size and temperament. That is useful for new owners and shelters alike.

A well-cared-for land crab usually lives somewhere between 5 and 10 years. They are an omnivore, so their nutritional needs shift with age, size and activity. Land crabs need both fresh and brackish water access plus deep damp substrate to burrow and molt in. They are territorial and will fight if kept too densely, so allow ample floor space per animal. Keep an eye out for failed molt, dehydration, limb loss from fighting. These are the conditions land crabs are most commonly seen for.

How does the Land Crab Species & Morph Identifier work?

The result is based on matching the traits you describe against commonly documented characteristics for land crabs, not genetic testing. Treat the result as a well-founded estimate. Every land crab is an individual, and your vet's judgement outranks any online tool.

Factors that matter

• Physical traits such as size: coloring and markings
• Behavioral traits: which can be just as informative as appearance for some questions
• Age: since juvenile traits can differ noticeably from adult ones
• Photo or description quality: the more specific your input, the more useful the match

How do you use the Land Crab Species & Morph Identifier?

1. Pick your adult size (Very small, Small, Medium, ...)
2. Pick your coat length (Hairless or very short, Short and dense, Medium, ...)
3. Pick your ear carriage (Erect, Folded or dropped, Semi-erect, ...)
4. Pick your overall build (Slender and fine-boned, Balanced, Stocky and heavy-boned)
5. Pick your dominant color pattern (Solid single color, Two-tone or bicolour, Brindle, merle, tabby or ticked, ...)
6. Press Calculate, then read the result alongside the sources listed below

If the result looks wrong, check your inputs before you worry. Entering weight in the wrong unit is easily the most common reason a figure looks off.

Before you rely on this

One number on one day is rarely the full picture. What matters more is the direction of travel: whether your land crab is trending steadily, drifting, or changing suddenly. A sudden change is always worth a call to your vet, even when the individual figure still falls inside a normal range.
