Identification Guide

Identifying the Tiger Lucine (Codakia orbicularis) involves observing specific features and comparing it with similar species. This guide provides key details on how to recognize this bivalve mollusk, its distinctive characteristics, and how it compares to closely related species.

How to Identify a Tiger Lucine (Codakia orbicularis)

The Tiger Lucine has a unique circular shell that is typically smooth with a beautiful pattern. It can grow up to 85 mm (about 3.3 inches) in length.

To identify it:

• Shape: Look for a rounded, circular shape.
• Pattern: Notice the fine cross-hatching on the surface.
• Color: Check for a light color, often with a lavender or pink tint along the inside.

These features help distinguish it from other shellfish.

Characteristics

The shell of the Tiger Lucine is notable for its symmetry and texture. The outer surface is usually ivory or pale white, while the inner shell may have a pale golden-yellow hue.

Key characteristics include:

• Foot Structure: The foot can extend and forms a tube that helps the mollusk draw in sea water.
• Lunule Shape: The lunule is heart-shaped, which is a distinctive feature.
• Teeth Structure: There are minimal posterior lateral teeth present in the shell.

These characteristics are important for proper identification.

Comparison To Similar Species

When comparing to similar species, especially the Dwarf Tiger Lucine (Ctena orbiculata), distinctions become clear.

Differences include:

• Size: The Dwarf Tiger Lucine is much smaller, about 25 mm (1 inch) long.
• Teeth: It has distinct posterior lateral teeth, which the Tiger Lucine lacks.
• Lunule: The lunule of the Dwarf version is longer and not heart-shaped.

Recognizing these differences is crucial for accurate identification in the field.

Distribution & Habitat

Tiger Lucine, or Codakia orbicularis, is primarily found in specific environments within the western Atlantic Ocean. Its distribution and habitat preferences play a crucial role in its life cycle and ecological interactions.

Where to Find Tiger Lucine (Codakia orbicularis)

Tiger Lucine is commonly located in sandy or muddy bottoms of the Gulf of Mexico and parts of the Caribbean. They inhabit areas at depths ranging from 0 to 93 meters.

These bivalves favor subtidal zones where they can bury themselves in the sediment. This behavior helps them avoid predators and allows them to retain moisture during low tides.

The species is native to regions stretching from Florida to the northern Caribbean Sea, making it a key component of these marine ecosystems. Their unique habitat preferences contribute to their ecological role in nutrient cycling and sediment stabilization.

Cultural & Economic Importance

The Tiger Lucine holds significance in both cultural contexts and economic activities. Its unique characteristics and habitat contribute to local traditions and fisheries, while its ecological role affects broader environmental practices.

Frequently Asked Questions

The Tiger Lucine, or Codakia orbicularis, plays a notable role in its environment. It has unique physical traits, specific habitat needs, and a distinct diet. Understanding these aspects helps highlight its importance and the challenges it faces.

How does the Tiger Lucine contribute to its ecosystem?

Tiger Lucines are important for maintaining the balance in coastal ecosystems. They help filter water by feeding on microorganisms, which contributes to water quality. Their presence also supports various predators that rely on them as a food source.

What are the distinctive features of Codakia orbicularis?

Codakia orbicularis has a circular, oval shell that can reach up to 85 mm (about 3.3 inches) in length. The surface of the shell shows fine cross-hatching and radial lines. The inner shell is often white, with occasional yellow or pink tinges on its edges.

What type of habitat is essential for the survival of Tiger Lucines?

Tiger Lucines thrive in sandy or muddy bottoms found in shallow coastal waters. They are commonly located along the Atlantic coast of North America, from Florida to the West Indies. Good water quality and stable substrates are crucial for their survival.

What diet do Tiger Lucines typically follow in their natural habitat?
