Description: Murex ternispina Lamarck, 1822 - black-spined murex snail shell, modern (latest Holocene) (~abapertural view) (~9.6 centimeters tall) This species is also known as Murex nigrispinosus. The gastropods (snails & slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments. Most gastropods have a calcareous external shell (the snails). Some lack a shell completely, or have reduced internal shells (the slugs & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores. Seen here is a muricid gastropod with a spinose shell. The high degree of spinosity is usually considered an anti-predation feature. Spinose muricids typically have three axially-oriented rows of spines per whorl, so that each spine row is ~120º from the next. Conchologists have pointed out that such spine row distributions provide orientation stability to the snail and prevent sinking on unconsolidated, fine-grained, high-water-content sediment substrates. Another suggestion holds that well-developed spine arrays could act as traps for potential prey. Muricids are predatory gastropods. They principally prey on encrusting, conchiferous organisms (e.g., bivalves, barnacles) by boring through the shells. It's likely that the spine arrays protect the snail from predatory arthropods or fish while engaged in boring & feeding on prey.

Description: Murex pecten Lightfoot, 1786 - Venus comb murex snail (abapertural view) (public display, Bailey-Matthews Shell Museum, Sanibel Island, Florida, USA) The gastropods (snails & slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments. Most gastropods have a calcareous external shell (the snails). Some lack a shell completely, or have reduced internal shells (the slugs & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores. Muricids are predatory snails having shells that are often spinose. They principally prey on molluscs - clams and other snails - by drilling through the prey animal's mineralized shell. Muricid drill holes are relatively small and circular. The Venus comb murex snail shown above is part of the Indo-West Pacific Province: "The world's largest and richest province extends from the Red Sea and East Africa across the Indian Ocean, then touches northern Australia and southern Japan to extend eastward throughout the "South Seas" to Hawaii and Easter Island. Probably 5,000 marine species are found in its shallow coral waters."

Description: Murex ternispina Lamarck, 1822 - black-spined murex snail shell, modern (latest Holocene) (abapertural view) (~9.6 centimeters tall) This species is also known as Murex nigrispinosus. The gastropods (snails & slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments. Most gastropods have a calcareous external shell (the snails). Some lack a shell completely, or have reduced internal shells (the slugs & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores. Seen here is a muricid gastropod with a spinose shell. The high degree of spinosity is usually considered an anti-predation feature. Spinose muricids typically have three axially-oriented rows of spines per whorl, so that each spine row is ~120º from the next. Conchologists have pointed out that such spine row distributions provide orientation stability to the snail and prevent sinking on unconsolidated, fine-grained, high-water-content sediment substrates. Another suggestion holds that well-developed spine arrays could act as traps for potential prey. Muricids are predatory gastropods. They principally prey on encrusting, conchiferous organisms (e.g., bivalves, barnacles) by boring through the shells. It's likely that the spine arrays protect the snail from predatory arthropods or fish while engaged in boring & feeding on prey.
