We determined the effect that growth status has on the feeding behavior of land pulmonates. We reared each of six pulmonate species on six different dietary regimes for 90 days from their hatching. In all species, growth rates differed significantly among diets. Four species grew best on a mixture of baby food and cucumbers. Either baby food or cucumber alone is nutritionally deficient, but they complement one another. Most species exhibited lower developmental performance on either cabbage or an artificial diet. In a follow-up diet choice test, slugs (Eleutherocaulis alte and Lehmannia valentiana) that had been initially reared on either cucumber or baby food preferred the other food item. However, a snail (Aegista mackensii) showing good growth on most diets indicated no preference. These data indicate that land pulmonates attempt to achieve better growth by compensatory feeding.
