What Happens When the Second Largest Whale Species Washes Up on the Beach?

In a rare and concerning event, a dead fin whale has been discovered on Cefn Sidan beach in Carmarthenshire, prompting an investigation by Marine Environmental Monitoring. This incident follows the stranding of a young long-finned pilot whale earlier the same day. Fin whales, the second largest species of whale, are seldom reported along the Welsh coast, making this a significant finding.

Key Takeaways

• A dead fin whale was found on Cefn Sidan beach in Carmarthenshire.
• This fin whale is believed to be a female, measuring over 21 metres in length.
• Fin whales are the second largest whale species, following the blue whale.
• Only four fin whales have been reported around the Welsh coast in the last 24 years.
• A young long-finned pilot whale died on the same day after becoming stranded.

Understanding the Fin Whale

Fin whales (Balaenoptera physalus) are magnificent creatures known for their incredible size and speed. They can reach lengths of up to 27 metres (88.6 feet) and weigh as much as 80 tonnes. These whales are characterised by their long, streamlined bodies and distinctive dorsal fins. Found in oceans worldwide, fin whales prefer deeper waters and are often seen in both coastal and offshore regions.

Why Are Fin Whales Rarely Seen in Wales?

Despite their vast range, sightings of fin whales in Welsh waters are incredibly uncommon. Marine Environmental Monitoring indicated that only four fin whales have been recorded in the last 24 years, with the most recent sighting occurring in 2020 in the river Dee. The rarity of these sightings can be attributed to various factors, including:

• Their preference for deeper waters.
• Environmental changes affecting their migratory patterns.
• Human activities, such as shipping and fishing, that may impact their habitat.

The Discovery at Cefn Sidan

On Monday, beachgoers reported the stranding of the fin whale. Upon examination by the environmental team, it was noted that the whale had been dead for some time and was in a severe state of decomposition. This state of decay made it challenging for experts to determine key details about the whale, such as its age or the exact cause of death.

Recent Stranding of Other Marine Species

Coincidentally, on the same day, a 12-month-old long-finned pilot whale was found stranded nearby. This incident highlights the ongoing concerns regarding marine mammal welfare along the Welsh coast. Stranding events can occur due to various reasons, including illness, environmental factors, or navigational errors during migration.

The Importance of Marine Monitoring

Marine Environmental Monitoring plays a crucial role in tracking and studying marine life along the Welsh coast. Their efforts help to gather data on marine species, assess the health of marine ecosystems, and respond to incidents like the recent whale strandings. The information they collect is vital for understanding the impacts of environmental changes and human activities on marine wildlife.

What Happens Next?

Following the discovery of the fin whale, Marine Environmental Monitoring will likely conduct further investigations to determine the cause of death. This may include:

• Collecting biological samples.
• Conducting necropsies to understand health issues.
• Assessing the impact on local marine ecosystems.

Additionally, the organisation may engage with local communities to raise awareness about marine conservation and the importance of reporting stranded marine animals.

Conservation Efforts for Marine Life

Conservation initiatives are critical to protecting marine species like the fin whale. Efforts include:

• Implementing protective regulations in vulnerable areas.
• Conducting research on whale populations and behaviours.
• Engaging the public in marine education and conservation efforts.

By enhancing awareness, communities can contribute to protecting these majestic creatures and their habitats.

FAQs

What is the size of a fin whale?

Fin whales can grow up to 27 metres (88.6 feet) in length and weigh as much as 80 tonnes, making them the second largest whale species after the blue whale.

How many fin whales have been reported in Wales?

In the last 24 years, only four fin whales have been reported around the Welsh coast, with the most recent sighting occurring in 2020.

What causes whales to become stranded?

Whales can become stranded due to various factors, including illness, environmental changes, navigational errors, or disturbances from human activities such as shipping.

What should I do if I see a stranded whale?

If you encounter a stranded whale, it's essential to contact local marine authorities or environmental monitoring organisations to report the sighting and receive guidance on the next steps.

Why is marine monitoring important?

Marine monitoring is crucial for tracking marine species, assessing ecosystem health, and responding to incidents like strandings, ultimately aiding conservation efforts.

As the discovery of the fin whale raises awareness of marine life in Wales, it also calls for ongoing conservation efforts to protect these magnificent creatures. How can we better support marine life in our oceans? #MarineConservation #FinWhale #CefnSidan
