Tectus
Tectus is a genus of medium-sized to large sea snails, marine gastropod mollusks in the family Trochidae, the top snails. These snails are commonly known as “top shells” or “trochus snails,” and are particularly well-known for their beautiful, colorful, and often highly ornamented shells.
Common Names
Besides "top shells" and "trochus snails," Tectus species are also known by various other common names, depending on the specific species and location. Some of the more common names include:
- Trochus
- Top Snail
- Trochus Shell
- Cat's Eye Shell (for Tectus niloticus)
- Rainbow Trochus (for Tectus niloticus)
- Trochus Snail (for Tectus fenestratus)
Characteristics
Tectus snails are characterized by their conical, solid shells, often with a rounded apex. The shells are typically adorned with intricate spiral ribs and sometimes colorful patterns. The aperture of the shell is usually rounded, and the operculum is a thick, calcareous structure that covers the opening when the snail retracts into the shell. The animal itself has a muscular foot and two long, slender tentacles. Tectus species exhibit a wide range of colors and patterns, making them highly sought-after by collectors.
Environment
Tectus snails are found in tropical and subtropical waters worldwide. They inhabit rocky shores, coral reefs, and seagrass beds, typically living in shallow waters. They are often found in areas with moderate wave action and strong currents. These snails are primarily herbivorous, feeding on algae and other plant matter.
