70 years of helping people to care for our ocean

Ragnar's Journey

28th January 2021 A sub-adult Crabeater seal (Lobodon carciniphaga) was seen by local residents resting on some rocks on a beach at Ramsgate which is situated on the KZN lower South Coast. Staff from the Lower South Coast SPCA branch were alerted and decided to capture the seal and transport it to uShaka Sea World for observation and possible treatment.

It is only the third recorded sighting of a Crabeater seal on the KZN coastline over the past 40 years.    As rare as these sightings in South Africa are, possibly even rarer still is the sighting of two Crabeater seals in South Africa on the same day.  Another Crabeater seal sighting was reported in Port Elizabeth on the same day as Ragnar’s arrival. Crabeater seals are true seals who call the coast of Antarctica home.   

Upon arrival uShaka Sea World, although resident veterinarian Dr Francois Lampen found him to be in good overall condition, he was understandably stressed.  The staff decided to call him Ragnar after the legendary viking Ragnar Lothbrok. He was admitted into one of the rehabilitation holding pools and left to rest and adjust to his new surroundings. As the coast of Antartica is almost totally devoid of human habitation, these seals have not evolved to fear humans – which is not necessarily a good thing.

The uShaka animal care staff, led by Dr Francois Lampen, are investigating the various possibilities which could have caused Ragnar to stray from his natural feeding grounds and end up on the KZN coast.  Crabeater seals do not eat crabs. They are specialist feeders feeding on the abundant krill of the Southern Ocean.  This presented an initial challenge but he soon started feeding well.

We are in consultation with seal specialist Dr Greg Hofmeyer from BayWorld in Port Elizabeth who has vast experience in marine mammal management for guidance on Ragnar’s care, treatment and reintroduction to the ocean. 

“Although Crabeater seals are the most abundant seal species in the world, Ragnar is unique and we will do our best to ensure that he is soon fit and strong enough to make his way back to the Antarctica.    He is really easy to work with as unlike most wild animals who are admitted, it appears he has little natural fear of humans,” said Senior Animal Behaviourist, Ursula Macklin.

On the 28th January we reported on a very rare visitor admitted to our rehabilitation facility. Since then, he has become quite a celebrity and has slowly crept into all our hearts.

Ragnar (as he was named soon after his arrival), is a sub-adult Crabeater seal who calls the Antarctic home. He is only the third recorded Crabeater seal that has been seen on the KZN coastline over the past 40 years.

When he arrived, although he was a little stressed after the journey from Ramsgate to Durban, he appeared to be in good health. We decided to leave him to rest and adjust to his new surroundings in his own time.

One of the ways the staff helped him adjust was to make loads of ice blocks which they placed both in and out the water. He loves to rest next to or on top of the ice blocks when he is on the side of the pool and whilst swimming, he pushes the ice around the pool.

For the first four days that he was with us, he showed little interest in humans and even less interest in the food he was offered. The main diet of Crabeater seals is live krill and therefore it was understandable that he did not initially recognise our efforts at offering him pieces of defrosted fish.

On the fifth day we started offering him his food with the lights off which seemed to do the trick as he began investigating the food with increased curiosity. After that he quickly developed a healthy appetite and is currently eating 3kgs a day. His favourite food is corvina and squid which he literally sucks up with a mouthful of water.

He has recently started to show great interest in the staff as they go about their duties. Unlike in the early days when he spent the entire day sleeping, he is now alert and checks on the staff as they walk past to see if they have a cooler box in hand.

“Although we are delighted that he has regained his confidence both in and out of the water, his association with humans and food is not a good thing. Going forward from today, we will remain out of sight when we feed him.” said Anna Eyre, one of his proud caregivers.

Plans are underway for Ragnar to be flown, courtesy of The Bateleurs to Bayworld PE next week.

On Friday morning (12th February 2021) we awoke to messages informing us of a beached elephant seal on Garvies beach which in on the Bluff, Durban.  Our first thoughts were bewilderment at the arrival of yet another arctic seal visitor so close to Ragnar’s arrival. 

Then to more practical thoughts of how to relocate a 130-kilogram seal from Gavies beach to uShaka Sea World.  Members of the Metro Search & Rescue, SAPS Search and Rescue NSRI and Ethekwini lifeguards once again came to the rescue and transported the seal to uShaka Sea World.

His arrival caused quite a dilemma as all the available rehabilitation pools were already occupied and we were uncertain whether he would be able to peacefully share Ragnar’s enclosure.  He was visually examined in his transport crate and then left to rest and recover from his ordeal whilst the seal and animal health teams set about researching artic seal behaviour. It was clearly evident that he had sustained an injury to lower jaw which we hoped was merely a superficial laceration. 

When he looked at the team with his big dark pleading eyes, it seemed appropriate to call him Dobby after the house elf in Harry Potter.

Over the weekend once we learned from seal expert, Greg Hoymeyer that it would be in order to place the two Antarctic seals together, we introduced Dobby to Ragnar.  It was Ragnar who seemed genuinely pleased at the arrival of a companion.  Dobby merely rested on the side of the pool, opened and closed his big eyes and seemed oblivious to Ragnars numerous snuggling attempts. 

They were later seen swimming in the pool together and we knew all would be ok.

Dobby will have to remain in our care until he has completed his moult (which can last up to four weeks) Elephant seals don’t usually feed or swim whilst they are moulting and spend the month lying around on the islands sleeping.  Dobby spends his days doing just that, sleeping.

Being true seals both Dobby and Ragnar have signature big dark eyes and snotty noses. 

 

18 February 2021 – There were mixed emotions when Ragnar took to the sky this morning. 

As the weather in Durban this morning was perfect, Ragnar was loaded into a bespoke transport crate and driven from uShaka Sea World to Virginia Airport and loaded onto a Bateleur’s light aircraft. Once again, when The Bateleurs heard that a stranded seal needed to be flown from Durban to Bayworld in preparation for release, they did not hesitate to volunteer their support.

Ragnar will spend the night in PE before being taken, courtesy of SAIAB, into the Agulhas current and released. The Agulhas current will assist the seals in the initial stretch of their journey back to the Antarctic.

Ragnar will not be alone because he will join Sebastian, a crabeater seal of similar age. Sebastian arrived in Port Elizabeth on the same day that Ragnar arrived on the KZN south coast. 

SAAMBR veterinarian, Dr Francois Lampen who accompanied Ragnar to PE, will carry out health assessments on both seals later this afternoon.  Scientists who are keen to learn more about crabeater seals and specifically vagrant crabeater seals, will take this rare opportunity whilst the seals are under sedation to take scientific samples.

They will both be fitted with satellite tags in order for us to monitor their movements post release.

“We are going to miss our little Viking who has wriggled and wormed his way into our hearts. The longer he spent with us, the more we were charmed by him.  Not only is he extremely beautiful, but smart, agile and curious – much like a young puppy.  We are however very proud that he has done so well and wish him well on his journey back home” said Lead Behaviourist Hayley Tennant.

We look forward to sharing Ragnar’s journey back to the Antarctic with you.
