A Whale of a Time

Sperm Whale at Perranporth
It felt like a pilgrimage. Hundreds of people were walking northwards from Perranporth along the shining pink road towards the beached whale.



We heard on the Sunday news that a female Sperm Whale was found beached near Perranporth and decided we just had to take the opportunity to see it in the flesh. We had underestimated how far from the nearest car park it was. Along with many others we walked 50 minutes to see the whale and another 50 minutes back to the car. The beach was covered in a pink tide by millions of Moon Jellyfish and the odd Blue Jellyfish. We judged we would have plenty of time to get there and back as the tide was ebbing from full. People of all ages were striding out with dogs and children. People who would normally just manage to walk a couple of yards from their parked car to empty the dog and get an ice-cream were making the journey.

Being two days after it had beached, the whale had been post mortemed on the beach with obvious incisions and jaw removed. The carcass was beginning to darken and bloat and the exposed entrails were bubbling and fizzing with the release of decomposition gasses.  
When the pilgrims arrived there were hushed conversations “Such a pity it had to die for us to see it.”, “They say some lads were trying to get souvenir teeth”, (in fact the autopsy team had removed the lower jaw with teeth to age the whale), “Well worth the walk to see it.”, “I’ve never seen anything like this before.”

On our return there was still a continual stream of people walking northwards to pay homage.

Post-mortem team
The following day I has a call about another stranding. This time, a female juvenile Minke Whale much closer to home at Bude. I was unable to get to it until the evening due to tides and commitments. Arriving at 9pm, there was a team of people from the Marine Srandings Network, British Divers Marine Life Rescue (BDMLR) and of course James the volunteer veterinary who was beginning the post mortem.

James was assisted by both divers, one handling and wrapping the samples, the other listing what these were – Kidney, Liver, Ovaries, Eyes, Heart, Stomach contents (Krill) with Niki the Strandings officer taking record photographs. Duncan was the local Strandings callout with us other three local yokels provided guidance and porterage to get them, the samples and equipment back up the cliff in the dark at 10:30pm.

What a difference in the two experiences – Perranporth, a long walk along a sandy beach to see a Sperm Whale – 11 metres long with a long thin toothed jaw for feeding on octopus and small fish; Bude a stiff climb to a rocky beach to find a Minke Whale – 7 metres long with a large jaw with baleen filters to eat Krill and small fish.

Minke Whale at Bude
Both were judged to have been live strandings. The Sperm had died as her organs collapsed without the support that the sea gives to it; the Minke probably driven ashore by perhaps Dolphins had, judging by pre mortem lacerations and bruises, injured herself fatally whilst trying to squirm back to the sea.



They say things happen in threes – let’s hope this old adage is wrong. Nice as it is to experience the huge marine mammals at close range, I would rather there were no more such strandings.

Stranding 7400

After a couple of false alarms, this week I had my first real Marine Stranding.

In September last year, about 30 volunteers attended a Marine Strandings Network workshop in the Parkhouse Centre in Bude.

Abby Crosby lead the day and described how the MSN operates then showed and described to us the typical species that are washed up on the Cornish beaches.

We then went through the recording process for the two most common strandings; Seals and Cetaceans. This was followed by a gruesome film showing what the volunteer veterinary surgeon has to deal with when a stranding is sufficiently fresh to be worthy of a post mortem examination. Thankfully this was after we had eaten lunch, not before!

The rest of the day was taken up with simulated recording exercises outside in the sun. First we practised on a blow-up dolphin then a seal.

.."placed under the waterfall"
After three long months the call came on Thursday afternoon that a dolphin had been washed up on nearby Sandymouth beach. The coordinator told me where it could be found and that it had been moved above the High Water mark as the tide was within an hour of High Tide. I also had to describe what I would be wearing in case of accidents so that the Coast Guard would know what to look for and agreed to phone in to confirm that I had found the stranding and successfully left the beach.

As agreed with my local colleagues on the training day, I phone Duncan who wanted to help. My kit had been packed for three months, but I still needed to go through my check list before driving the mile or so to Sandymouth.

The carcase was immediately visible when I arrived at the beach. Unfortunately the considerate people that had reported it have moved it almost directly under a waterfall. The strong onshore wind was blowing the stream of water regularly over the corpse drenching it and anyone who approached it.

Duncan and I moved it to where we could photograph and record and tag it as Number 7400. A concentrated 45 minutes followed while we went through the procedure we had been taught. Duncan had already recorded a couple of seals so his expertise was most useful. We were battered by the wind and covered copiously in the blowing spume.

Common Dolphin - Stranding 7400
My first stranding was a beautiful Common Dolphin. It had lost one eye and suffered a broken jaw, but on the post mortem can explain why it died. It was a privilege to see one of these magnificent animals at such close quarters, to touch its skin and gaze into its eye. It is such a pity it had to die so that I could have that experience.t
