Cornish Seal Sanctuary announces death of Diego the rescue

The Cornish Seal Sanctuary has announced the death of one of its resident sea lions, Diego.

Diego, who was taken in by the charity in 2009 alongside his brother Noito, died at the sanctuary on Sunday 17 December following sickness.

In October 2023, Diego experienced issues with paraphimosis, a urologic emergency that caused extreme inflammation and required urgent medical intervention.

Despite initial success, a second setback in the weeks before his death saw him develop more complications.

The sanctuary decided it would be best to put Diego down, so as not to prolong his suffering.

It's awaiting lab results from a post-mortem examination to understand the cause of Diego's sudden deterioration.

In a Facebook post, the sanctuary shared an emotional tribute to Diego.

Elliot Badrick, Senior Animal Care Specialist and Diego’s primary trainer said: "Diego called the sanctuary home since he arrived in 2009 along with his brother Noito. From the beginning, he was a joy for the team who cared for him and kept them entertained every day.

"From sitting on his rock (that he loved to jump off) to monitoring the daily antics of the animal care team, he always knew what was happening around him – especially when the team was on the way to deliver his tasty mackerel or new toys to play with!

"Often compared to a giant labrador, he had few boundaries when it came to personal space (luckily, our team was prepped for it!).

"Sometimes, he would accidentally rest his flippers on their feet or, when asked to lie down for a body check, would make sure to come as close as possible, seeking assurance that everything was going to be okay.

"He was also very loyal. When Diego was building a relationship with a new member of the team, he would look with great suspicion to his primary caregivers as if to say, 'why are you letting this person feed me? I think it is probably best if you take over!'

"Every morning, Diego was there to greet the team at the underwater window, where he would boop his nose against the glass. He also loved to play hide and seek, chasing the team up and down through the windows.

"Diego had so much trust with his primary caregivers, even up to his last days with us. A sensitive soul, he almost seemed embarrassed by his most minor slip ups.

"Sometimes, he would be so eager to interact with his trainer, he would trip over his cumbersome front flippers and then roar out of pure humiliation!

"With his adorable and cheeky nature, Diego loved to push boundaries – for example, at the end of training sessions, Diego knew he would have to stay in the water whilst the animal care team left the enclosure.

"However, instead, he would always walk up the steps towards the team until they stopped and looked at him. He knew he was being cheeky and would slowly slip into the water, head resting on the side of the pool, and waiting for that last big handful of fish, letting him know he had been a good boy.

"He loved learning, though, and one of his favourite things was going in his transport cage; he was always eager to please and never wanted to let his team down. When learning new behaviours, he was always proud to show off his new talents (even after seeming to question why he needed to learn it in the first place).

"Over the past year, Diego flourished, becoming his own sea lion and building an unbreakable bond with his team, who adored him.

"Diego will no doubt leave a large void at the Sanctuary, especially for those who cared for him daily. Just as the team was there for him, Diego was always there for them, too. He knew many a secret and would always be there for a little chin scratch - a bright spot, even on a bad day."

The Cornish Seal Sanctuary has thanked supporters who have shared their well wishes with the team.

It added: "As we say goodbye to Diego, we would like to thank everyone who has been so supportive to our animal care team at this hard time, and the wider Cornish Seal Sanctuary team, who will miss him so much.

Members of the public have flooded the comments with their very own pictures of Diego.
