Having received innovative chemotherapeutic care at the Vancouver Aquarium, beloved sea otter Milo, died from lymphoma (a type of cancer) on Wednesday, January 11, 2012. Milo will be missed and we thank everyone who has sent us positive wishes and thoughts over the past months.

Milo rose to worldwide fame when he was filmed holding paws with companion Nyac four years ago. The online video has been viewed by over 16 million people worldwide.

Milo was the first live sea otter to be diagnosed with lymphoma and the first sea otter treated with chemotherapy in the world. Since his diagnosis in August 2011, Vancouver Aquarium’s veterinary team consulted with veterinary oncologists, pathologists, researchers, internists and other specialists from around the world to create a unique treatment plan for Milo. His response to treatment had been very positive for almost six months. Between intensive treatments, Milo spent time in his sea otter habitat with companion Tanu.

The collaboration of veterinary specialists from around the world to create a unique chemotherapeutic treatment plan for a sea otter has resulted in important knowledge that will improve our understanding of sea otter diseases and responses to treatment. Dr. Martin Haulena will be reviewing the preliminary results of the treatment plan and outcomes over the next few months and will share this knowledge with international colleagues to help advance veterinary care in future cases.

    Milo you were the reason I visited Vancouver from Australia. My husband bought you as an adopted otter for me for my birthday. Then he gave me a ticket to fly to Vancouver to see you. I was lucky enough to not only see you but to help feed you. I am so saddened by your passing, but I have many good memories from that trip back in 2009 and lot of video footage of me feeding you. I will never forget you…Vale Milo

    I will never forget how special you made my visits to the Aquarium, Milo. Although I was only visiting Vancouver for about a week, I ventured to the aquarium twice, opting to add the sea otter trainer tour on my second visit… all because of you. I even got to feed you some lovely clams! 🙂

    Your life meant so much to so many, and I hope that your legacy is carried on through conservation efforts and awareness about issues that impact sea otters in the wild and captivity.

    Much love, Milo… Happy swimming in that big ocean in the sky. xo

    You were a lovely otter in life Milo, so cute, and I will always remember your little black nose. I’ve been watching the webcam for over a year, and on days when I wasn’t well enough to go outside, watching you swim brought me comfort. You were a brave otter, I never guessed you were sick, and hopefully your suffering was minimal, but even so your illness and treatment seems to have helped teach your people at the aquarium a lot about cancer and its treatment: you are a hero among otters now, Milo!

    I’ll always think of you whenever I eat fish,
    Farewell to you, Milo, my favourite otter.

    R.I.P. little Milo. Now you can hold hands with Nyac again in heaven. The sea otter tank is always the highlight of the aquarium visit every time I go. Thank you to the aquarium team for doing such a great job looking after him.

    Milo: you were a great little sea otter. Although I live in the UK I have visted you everyday when I have been in Vancouver each year. I will miss you so much. I watched you for ages and you had your own personality. I loved every minute! Thank you to the hardwork of the aquarium staff who did their best for Milo – it must be very upsetting.. My thoughts are with you. x

    The otter tank was always the first exhibit we visited when we went to Stanley Park Zoo many moons ago. We could spend hours watching them putter around.

    RIP Milo.
