- Comments: The slender walker is a habitat specialist. It is found only in one Atchison
County marsh that is fed by artesian flows. Due to the rarity of this type of habitat in
Kansas, this snail is considered endangered. The closest known colony is in Missouri. The
isolated population is vulnerable to man-made and natural events such as pollution or
severe droughts. This snail measures just 1/4 inch in length and can live up to 2.5 years.
The sex ratio is about three-fourths female. The slender walker is considered an
amphibious snail and will lay eggs on wet sod. Its omnivorous diet consists of both plant
and animal matter. The quantity and quality of groundwater is critical to the continued
existence of this organism. Its presence is an indication of healthy groundwater
conditions.
