Mammal Diversity
The ASM's Mammal Taxonomy
Free
A fresh new update to closely match the website and other platform versions.
This app is built to complement the web version of the Mammal Diversity Database (MDD). This app is tailored for biologists, conservationists, researchers, and nature enthusiasts. It provides offline access to an updatable mammal database of taxonomic and biodiversity information. The Biodiversity Committee of the American Society of Mammalogists (ASM) compiles and maintains MDD.
The app utilizes a high-performance native database engine and framework to query mammalian taxonomy, names, and synonyms worldwide.
Key Highlights:
• 100% OFFLINE DATA
Never worry about satellite signal or cellular reception. The database is packaged locally, offering immediate access to taxonomic records without internet dependencies.
• COMPREHENSIVE TAXONOMIC DATA
Access the status of 6,700+ recognized living and recently extinct mammal species, including:
- Valid binomial names and publication citations.
- Detailed nomenclatural histories containing over 50,000 synonymized names.
- Country, continental, and biogeographic realm distributions.
- Type localities and specimen documentation.
• ROBUST MULTI-CRITERIA SEARCH
Find exactly what you need with an advanced, multi-parameter search engine. Filter by order, family, genus, specific epithets, synonymies, or localized regions with instant responsive results.
• RESEARCH-READY CSV AND JSON EXPORTS
Filter by specific taxonomic groups, families, or search results, then export directly to standard CSV or JSON files
Use the MDD app for fieldwork, classroom instruction, and scientific writing. Download the MDD app today.

What is New in This Version!
We have rolled out a major update to align the app closely with the MDD website and introduce new features for exploring taxonomic data:
What is New
* Better Visual Alignment: The synonym section formatting, synonym authors' styling, and the overall app color scheme now closely match the website.
* Cleaner Layout: We have streamlined the "Name Usages" display under synonyms to remove clutter and improve readability.
* Text Selection: You can now select and copy text directly from the taxonomy and synonym sections.
* Deep Analytical Insights: View proportions of specimen type categories, and easily identify species with the highest count of names and synonyms.
* Advanced Map Tools: View both known and predicted species distributions on the map, with a new option to center the map view instantly.
* Type Locality Search: Search and filter specimen records directly by their type locality.
Fixed and Improved
* Fixed species queries to properly order results by species instead of epithet.
* Resolved visual transparency and padding layout issues.
* Fixed external links and source code URLs.
* General text cleanups and performance polishing.
Thank you for your continued support!
