Ireland's Waters Remain a Safe Haven for Endangered Basking Sharks

Topic: Environment

A new study found that Ireland's waters continue to provide a safe haven for basking sharks. Researchers analyzed almost 50 years of basking shark sightings and identified several hotspots where the species returns year after year. The study suggests that Ireland offers important habitat for this globally endangered species.

Ireland's waters are still a safe haven for basking sharks, one of the world's largest fish species.

A new study published in the journal Endangered Species Research analyzed almost 50 years of basking shark sightings around the Irish coast. The researchers identified several hotspots where the species returns year after year, including the Blasket Islands in County Kerry and the south coast of County Cork. These areas are important for the sharks' survival as they provide food and shelter.

The study found that basking sharks return to Irish waters predictably each year, with sightings peaking during the spring and summer months. This is likely due to the seasonal peaks in plankton, which the sharks feed on. The researchers believe that Ireland's waters offer important habitat for this globally endangered species.

Basking sharks are harmless to humans and can grow up to 11 meters (36 feet) in length. Despite their size, they feed almost exclusively on tiny plankton filtered from seawater. Unfortunately, the species has declined in many parts of the world due to centuries of targeted hunting and recent pressures such as accidental capture in fishing gear and ship strikes.

The study relied heavily on data reported by members of the public to the Irish Whale and Dolphin Group and Irish Basking Shark Group. This highlights the importance of involving the public in research and conservation efforts.

Why It Matters

This discovery is important for India's marine ecosystem as it shows that some areas can remain safe havens for endangered species. It also highlights the need for continued conservation efforts to protect these species and their habitats.
