Wentletrap Triumvirate
Like wentletraps? Here are from left: Angulate, Humphrey, and Tollin wentletraps (from left, Epitonium angulatum, E. humphreysii, and E. tollini), .three species living along the coast of Southwest Florida. Observe how the Humphrey Wentletrap has a much darker operculum (the “trapdoor”) when compared to the two other species! And Tollin Wentletrap is the smallest and daintiest among the three species, usually reaching only about 5 mm (or 0.2 inch; the photos are not to scale)
