I have been assigned to write a 5 page essay that gives 2 sides to a controversial topic, then I must discuss what each side is trying to prove, then discuss which side I personally agree with.
NATURALLY I’m going to do captivity.
So what I need from you procaps is an article. Preferably I would like for it to discuss all cetacean captivity, but one specifically discussing Orcas will do well also.
This article needs to cover all of the main arguments in favor of keeping cetaceans captive, and it needs to be valid, meaning I can’t link someone’s tumblr post or anything, it has to be a credible valuable source. If you want to give me a link from Seaworld themselves or another marine park-affiliated source that’s fine, but it just has to be a genuine article.
Please reblog this with your best pick(s)! It would be really helpful and it will help your stance be better represented when these essays are presented and debated in my class!
Obviously not a pro-cap but a while ago whilst compiling a masterpost for mother/calf separation I was sent this document for the pro-cap side created by the European Association for Aquatic Mammals, who are definitely pro-cap.
A lot of captivity info in there. Mostly on dolphins, a few mentions of Orca (which I think you’ll probably find is scientifically incorrect when it comes to their pod structure, so that’s certainly interesting), some discussion on ‘cetaceans’ generally. Plus full bibliographies which might also be helpful in providing more pro-cap info for you if you drop the names or whatever into google :)
Who is Stumpy?
She is (in my opinion at least) the most important wild orca to roam these oceans. Her ID is X163, and here is a bit about her….
She is hypothesised to have been hit by a boat in 1996, her severed fin, crushed left side ribcage and deformed spine are an indicator of that. When she was first spotted with her mother in the same year it was assumed she would not survive.
Then when she was re-sighted years later in 2003 her mother was gone and she was with a different pod. She has been seen with many different pods since, 6 in particular have been witnessed provisioning her. It is possible they are all part of an extended family.
This kind of pro-social behaviour (voluntary behaviour intended to benefit another) is rare in the wild (survival of the fittest) and the same with ‘Adoption’ it is seen in animals such as dogs where they will rear young often of a different species but the usual reason for that is the mother has lost her original offspring and retains and urge to fill the maternal instinct.
But Stumpy is different, she has been taken in not by single females but by whole pods, often swimming in the wake of adult males to help keep up with the pod.
If they’re even distantly related helping Stumpy would mean protecting at least some of their own gene pool. However sometimes this must come at quite a cost when fish are in short supply a quote from one of the scientists (Heike Vester) who study’s the Norwegian population;
"In such a community, the entire group is important, so they wouldn’t leave sick individuals behind,”
Physiological evidence supports this idea. In zoos specialised ‘spindle’ cells previously thought unique to primates were found in Killer whale brains. These cells are located in the area responsible for speech, social organisation and empathy, and are credited with allowing us to feel love.’ X
Killer whales have often been thought of as our marine counterparts. They live in close-knit families; they are highly intelligent; they have languages and cultures; and they can also be brutal.
"Maybe killer whales are even more similar to us than we suspected.”

can we please get rid of the term “sea panda”
god it’s so awful
That inquisitive orca is back at the surfing beach Uluwatu in Bali!
He was spotted about 2 weeks ago checking out the surfers; he made a reappearance again today.
Apparently he’s from a pod of orcas from Sri Lanka, and might have a harpoon stuck in his tail from a run-in with traditional whalers.

SRI LANKAN ORCAS: AN OVERVIEW
The orcas that visit the waters of Sri Lanka are not well known and are quite mysterious; in fact, only 11 individuals have been identified. The Orca Project Sri Lanka was started in 2013 in order to better understand the orcas that frequent the island. Even though there are many unanswered questions about these whales, here’s what we do know:
- They are likely wide-ranging, mammal-eating orcas.
- They have been seen preying upon sperm whales, beaked whales and blue whales; the most recent and well-documented attack on sperm whales by orcas in Sri Lanka can be seen here.
- Orcas have been seen near Mirissa, Kalpitya, and Trincomalee.
Sri Lanka is an island off the southern tip of India:
As you can see, orcas have been spotted all around the island.
Because Sri Lankan orcas are so elusive and hard to find, only 11 individuals have been successfully photo-identified and cataloged. All orcas are assigned a code, and a nickname. Let’s look at the male orca OM005 “Titan”. The ‘O’ stand for orca, and the ‘M’ stand for Mirissa, the place he was first spotted. and ‘005” means he was the 5th whale to be added to the catalog. All of the whales’ ID codes start out with “O”, but the second letter depends on where they were first seen. It can either be “M” for Mirissa, “K” for Kalpitya, or “T” for Trincomalee, or “O” for other.
Here are the ID charts for all 11 cataloged whales:

Orca whale watching Vancouver Island, Canada.
This is Gulf of Alaska transient (GOA) AT37 Lituya. She was recently spotted by NGOS a few days ago traveling with her family in Montague Strait.
AT37 Lituya is a successful matriarch and mother. She has had three confirmed calves in the past ten years: AT80 Yakutat, AT81 Yakutaga, and a newborn calf who was born sometime this year. She also has a probable adult son, AT72 Spencer.
Fun fact: AT37 Lituya was tagged a few years ago and her and her family traveled nearly 2,500 miles in a single month!
