The provided source materials offer detailed information regarding free hermit crab adoption programs, educational resources, and advocacy tools available to U.S. consumers. Unlike typical consumer product samples or promotional offers, these resources focus on the rescue and responsible care of hermit crabs, as well as efforts to protect wild populations. The primary sources for this information are the Land Hermit Crab Owners Society (LHCOS), Hermit Harbor, Plight of the Hermies, and the LHCOS Advocacy Resource Hub. These organizations provide structured programs for adopting crabs in need, comprehensive care guidelines, and downloadable materials for public education.

Free Hermit Crab Adoption Programs

Hermit crab adoption is available as a free service, though it requires a rigorous application process to ensure the animals' welfare. The primary adoption program operates through the Land Hermit Crab Owners Society (LHCOS), which manages a database of available crabs and approved adopters across the United States. Effective September 29, 2021, all adoptions facilitated by Hermit Harbor transitioned to the LHCOS system.

To participate in the adoption program, applicants must meet specific eligibility criteria regarding habitat setup. The adoption is free, but the requirement is that the applicant possesses an appropriate "crabitat" established prior to application and is familiar with proper hermit crab care.

Habitat Requirements for Adoption

The documentation outlines strict requirements for the enclosure, or "crabitat," which are mandatory for adoption approval:

Tank Size: An aquarium of at least 20 gallons is required, with a recommendation for larger sizes. The general rule is 10 gallons of tank space per hermit crab.
Lid: The aquarium must have a secure lid to maintain humidity levels and prevent crabs from escaping.
Substrate: The substrate depth must be at least 6 inches to allow for burrowing, which is essential for molting and stress relief.
Temperature and Humidity: A constant temperature between 75 and 82 degrees Fahrenheit is required. Humidity levels must be maintained between 75% and 85%.
Water: Crabs require access to both freshwater and saltwater pools deep enough for full submersion.
Enrichment: The habitat must include items for hiding, climbing, and exercising.
Shells: An assortment of suitable shells must be provided, with a minimum of three shells per crab. These must be available in increasing sizes as the crabs grow.

Dietary and Care Guidelines

Adopters must be prepared for the long-term commitment of hermit crab ownership. The animals can live for 40 years or more, though determining age based on size is difficult.

Diet: Most pet store food is identified as nutritionally insufficient and potentially toxic. Adopters are instructed to provide a varied diet covering all food groups.
Handling: Hermit crabs should not be handled or played with. They are prey animals, and handling causes stress and fear. Furthermore, removal from the humid environment causes suffocation, as they have modified gills requiring moisture to breathe.
Social Needs: Despite the name, hermit crabs are social animals. They should be kept in multiples within an adequately sized enclosure.

Educational and Advocacy Resources

Several organizations provide free educational materials and advocacy tools to promote responsible ownership and protect wild hermit crab populations. These resources are available for download and distribution.

Plight of the Hermies

This organization focuses on educating the public about the issues facing hermit crabs in the souvenir trade. They advocate for adoption over purchase, noting that wild-caught crabs often die quickly due to improper care, toxic painted shells, and lack of humidity.

LHCOS Advocacy Resource Hub

The LHCOS Advocacy Resource Hub offers a "one-stop shop" for downloadable materials, campaign ideas, and educational tools. The goal is to protect wild hermit crabs and promote responsible pet care.

Available Materials: * Handouts and Printables: These include flyers and infographics designed for distribution at vet offices, pet stores, classrooms, and events. * Social Media Campaigns: Pre-made graphics and captions are available for sharing across platforms to drive engagement. * Wearables: The organization suggests wearing catchy shirts or hats from crabby organizations to serve as conversation starters.

Reporting Illegal Activity

The advocacy resources include instructions on how to report illegal animal sales and poaching on social media platforms: * Instagram: Users can report specific posts or seller accounts for violating Community Guidelines regarding animal abuse or the sale of endangered animals. Reports can be made anonymously. * Facebook: Users can report posts violating community standards against unauthorized sales.

The Impact of the Souvenir Trade

The source materials detail the negative impact of the exotic pet trade on wild hermit crab populations. Millions of crabs are taken from beaches annually for the souvenir trade. Before sale, they are often kept in crowded conditions and forced into colorful painted shells, sometimes having their natural shells cracked off. In captivity, high mortality rates result from improper care, specifically inadequate humidity and temperature, and the lack of deep substrate for molting.

Conclusion

The available resources provide a comprehensive framework for obtaining hermit crabs through free adoption programs rather than purchasing them from commercial sources. The primary mechanism for this is the LHCOS adoption database, which requires applicants to demonstrate a fully equipped and suitable habitat. Additionally, various organizations offer free educational and advocacy materials to support responsible care and discourage the poaching of wild populations. These resources emphasize that hermit crab ownership is a long-term, costly commitment requiring specific environmental controls and a non-handling approach to care.
