Green ormer

Green ormer (Haliotis tuberculata), also known as the European abalone, is a species of sea snail in the family Haliotidae, or abalones. It is found in coastal waters of the North Atlantic Ocean, including the Channel Islands, the western parts of the Mediterranean Sea, and along the coast of Europe and North Africa. The green ormer is a subject of commercial fishing and aquaculture due to its prized meat and unique shell.

Description

The green ormer has a distinctive ear-shaped shell, which is strong and slightly convex. The outer surface of the shell is rough with irregular growth lines and is predominantly greenish-brown, which camouflages it against the seaweed and rocks of its habitat. The interior of the shell is smooth, with a beautiful iridescent sheen, making it a popular item for jewelry and decorative items. The shell can grow up to 20 cm in length, but most specimens are smaller.

This species has a row of respiratory pores, or "holes", along the shell's outer edge, which are characteristic of all abalones. The green ormer's muscular foot allows it to cling tightly to rocky surfaces, and it uses its radula (a tongue-like organ with teeth) to graze on algae.

Habitat and Distribution

Green ormers are found in shallow waters, typically from the intertidal zone down to depths of about 15 meters. They prefer rocky areas where they can find shelter and ample food supply. Their distribution includes the temperate and subtropical waters of the North Atlantic, the Channel Islands, and the Mediterranean.

Conservation and Threats

The green ormer has faced significant population declines due to overfishing, habitat loss, and pollution. In some areas, strict regulations have been put in place to manage and conserve their populations. These measures include limiting the fishing season, restricting the size of the catch, and implementing licensing systems for fishermen.

Culinary Uses

In regions where they are found, green ormers are considered a delicacy. They are prepared in various ways, including stewed, fried, or baked. However, due to their declining numbers, green ormers are less commonly found on the menu and are often replaced by other abalone species from sustainable aquaculture sources.

Cultural Significance

In addition to their culinary value, green ormers hold cultural significance in some coastal communities. Their shells have been used historically for decorative purposes, including in jewelry and as inlay in furniture and musical instruments.
