The lava builds up on the surface and solidifies creating the initial structure. Hornitos can grow and exceed 10 meters in height (wikipedia) [13:18:07] @Joana though I haven't seen that the sponge was used for the wedding gift, the Japanese name of the sponge means "old shrimps lives in same hole" originally Chinese phrases.

[15:33:46] @Chris Can you please send me, if you have one, a paper describing the differences between the Peltaster and Plinthaster, specifically in refence to the close up on the plates and papullae? I thought was able differentiate them, but I might be confusing myself. [15:34:00] @Deb Oh absolutely! [15:34:36] Plinthaster plates are smooth, Peltaster has granules.
