CRYSOMALLON SQUAMIFERUM PDF

Chrysomallon squamiferum , commonly known as the scaly-foot gastropod , scaly-foot snail , or sea pangolin [3] , is a species of deep-sea hydrothermal-vent snail , a marine gastropod mollusc in the family Peltospiridae. Chrysomallon squamiferum differs greatly from other deep-sea gastropods, even the closely related neomphalines. The shell is of a unique construction, with three layers; the outer layer consists of iron sulfides , the middle layer is equivalent to the organic periostracum found in other gastropods, and the innermost layer is made of aragonite. The foot is also unusual, being armored at the sides with iron-mineralised sclerites.

Posted By Nadine Lymn on Jan 29, It is unlike any other known natural or synthetically engineered armor. Our study suggests that the scaly-foot gastropod undergoes very different deformation and protection mechanisms compared to other gastropods.

It is very efficient in protection, more so than the typical mollusk. Potential predators that are found in the same regions as C. Another vivid example of the evolutionary race between prey and predator which in this case also holds promise for better protective materials for humans.

Even in these extreme conditions, diversity is abundant for those lifeforms which have adapted to the seemingly inhospitable ecosystem. One of the wackiest and most impressive creatures from this particular area is the scaly-foot gastropod Crysomallon squamiferum , a snail with a shell of iron and plates of chainmail covering its otherwise squishy foot. Additionally, the snails are just massive, considering their environment. As a result, these snails are about three times the size of other hydrothermal vent snails. Well, behind glass - the sulfides react with the air so we kept them in their jar. Species description in the Journal of Molluscan Studies.
