Slug Species & Morph Identifier

What is the Slug Species & Morph Identifier?

The Slug Species & Morph Identifier identifies likely species or morph of slugs 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 slug usually lives somewhere between 1 and 3 years. As a herbivore, what a slug needs from its diet changes across its life stages. Pet slugs need consistently damp substrate and high humidity, since without a shell they dry out faster than snails. They are nocturnal and need a tightly fitting but ventilated lid. The usual suspects for this species are desiccation, chemical sensitivity, mites, so any noticeable change is worth following up.

How does the Slug Species & Morph Identifier work?

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

What affects the result

• 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 Slug 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

This calculation assumes a healthy adult slug with no complicating conditions. Pregnancy, recovery from illness, medication and significant age at either end of the scale all change what is appropriate. When in doubt, the safest move is to take the number to a vet and ask whether it fits your particular animal.
