Patella ferruginea is a species of limpet in the family Patellidae. It is commonly known as the ferruginous limpet. This species is considered one of the most endangered marine invertebrates in the Mediterranean Sea.

Description

Patella ferruginea has a robust, conical shell that can reach up to 10 cm in diameter. The shell is characterized by its strong radial ribs and a distinctive reddish-brown coloration, which gives the species its common name. The interior of the shell is typically white with a central muscle scar.

Distribution and Habitat

Patella ferruginea is endemic to the western Mediterranean, with populations found along the coasts of Spain, France, Italy, and North Africa. It prefers rocky intertidal zones where it can attach firmly to substrates.

Ecology

This species plays a crucial role in the intertidal ecosystem. It is a grazer, feeding primarily on algae that grow on the rocks. By controlling algal growth, Patella ferruginea helps maintain the balance of the intertidal community.

Conservation Status

Patella ferruginea is listed as Endangered on the IUCN Red List due to habitat loss, pollution, and over-collection. Conservation efforts are focused on habitat protection, legal regulations, and public awareness campaigns to prevent further decline.

Reproduction

The reproductive cycle of Patella ferruginea involves external fertilization. Spawning typically occurs in the warmer months, and the larvae are planktonic before settling onto suitable substrates where they develop into juvenile limpets.

Threats

The primary threats to Patella ferruginea include coastal development, pollution, and illegal collection. The species is also vulnerable to climate change, which can alter its habitat and food availability.
