Patella ulyssiponensis

Patella ulyssiponensis, commonly known as the Portuguese limpet or China limpet, is a species of sea snail, a marine gastropod mollusk in the family Patellidae, the true limpets.

Description

The Patella ulyssiponensis is a small to medium-sized limpet with a conical shell. The shell is typically 30-40mm in length, but can reach up to 60mm. The exterior of the shell is usually a dull grey or brown, while the interior is a shiny white with a blue or green tint. The shell is strong and thick, providing protection against predators and harsh environmental conditions.

Distribution and habitat

The Patella ulyssiponensis is native to the coasts of Western Europe, from the British Isles to Portugal, including the Azores and Madeira. It inhabits rocky shores, especially those exposed to strong wave action. It is typically found in the mid to upper intertidal zone.

Ecology and behavior

The Patella ulyssiponensis is a herbivore, feeding primarily on algae which it scrapes off the rocks with its radula. It is known for its homing behavior, returning to the same spot on the rock after foraging for food. This behavior is thought to be an adaptation to the harsh intertidal environment, allowing the limpet to maintain a 'home scar' that fits its shell perfectly, thus providing maximum protection against desiccation and predation.

Conservation status

The Patella ulyssiponensis is not currently considered to be at risk of extinction. However, like all marine species, it is potentially threatened by habitat loss and degradation, pollution, and climate change.
