Ceratostoma foliatum, a collage. The top two photos show the rocksnail likely feeding on some barnacles. These two photos were taken a day apart... it didn&rsquo;t move much. The lower two photos show an uninhabited shell to show the three wing-like projections that are said to allow the snail to land properly if dislodged from a rock by a predator while underwater. The large &ldquo;tooth&rdquo; can be seen projecting from the aperture. <br /> <a href="https://www.centralcoastbiodiversity.org/leafy-hornmouth-bull-ceratostoma-foliatum.html" rel="nofollow">https://www.centralcoastbiodiversity.org/leafy-hornmouth-bull-ceratostoma-foliatum.html</a><br /> <figure class="photo"><a href="https://www.jungledragon.com/image/83666/a_leafy_hornmouth.html" title="A Leafy Hornmouth!"><img src="https://s3.amazonaws.com/media.jungledragon.com/images/2839/83666_thumb.jpeg?AWSAccessKeyId=05GMT0V3GWVNE7GGM1R2&Expires=1759968010&Signature=xyP%2FrY%2B2GIy3wOmLP%2BFJ7i1FtuM%3D" width="200" height="152" alt="A Leafy Hornmouth!

      Thanks, Ferdy! These shells are quite the prize to find and even better to find a “live” one. At this time of the year they seem to be common. Their common name, never really thought of it till now, is quite descriptive; leafy varices and a horn-like “tooth”. Posted 6 years ago

        Good reminder for me to set the common name on the species record, as Wikipedia makes no mention of it. Done :) Posted 6 years ago
