Identification Guide
Identifying the Threaded Abalone (Haliotis asinina) involves several key features. Recognizing their distinct characteristics is crucial to differentiating them from similar species. Here’s a breakdown to help with proper identification.
How to Identify a Threaded Abalone
To identify a Threaded Abalone, focus on the shell shape and texture. These abalones have a long, narrow, and curved shell that resembles a donkey's ear. The outer surface is typically rough and can have a greenish or brownish hue.
The most notable feature is the threadlike ridges that run longitudinally along the shell. Look for 6 to 8 visible holes near the shell's edge. These breathing pores are essential for their survival. The body is usually a soft, greyish color when viewed from the inside.
Characteristics
Threaded Abalone possesses unique characteristics. The shell can grow up to 15 cm in length. It is thick and well-defined, making it heavy compared to other marine gastropods.
The inner shell is often iridescent, displaying vibrant colors such as blue or green. The foot of the abalone is wide, allowing it to attach firmly to rocks and reefs.
In terms of diet, they primarily feed on algae, which affects their habitat selection. Their natural environment includes rocky subtidal zones where algae growth is abundant.
Comparison To Similar Species
When comparing the Threaded Abalone to similar species, notable differences appear. The most commonly confused species is the Black Abalone (Haliotis cracherodii).
While both species have a similar shape, the Black Abalone has a darker, smoother shell with fewer holes.
Another similar species is the Green Abalone (Haliotis fulgens), which has a bright green outer shell and is thinner overall.
In contrast, the Threaded Abalone has distinct ridges and a thicker shell, making it easier to distinguish once familiar with the features.
