The middle organic layer appears to absorb mechanical strain and energy generated by a squeezing attack (for example by the claws of a crab), making the shell much tougher. The organic layer also acts to dissipate heat. Features of this composite material are in focus of researchers for possible use in civilian and military protective applications.\u201d <\/p>\n<cite><em>\u201c<\/em><a href=\"https:\/\/en.wikipedia.org\/wiki\/Scaly-foot_gastropod\">Scaly-foot gastropod<\/a><em>\u201d via Wikipedia<\/em><\/cite><\/blockquote>\n\n\n\n<p>These are the only living animal known to use iron in their skeleton.
