Omega 3s are also found in plants. This is where animals get theirs.
"While purslane is low in total fat, a large portion of the fat it does contain is in the form of omega-3 fatty acids. In fact, it contains two types of omega-3 fatty acids, ALA and EPA. ALA is found in many plants, but EPA is found mostly in animal products (like fatty fish) and algae."

I'll be making verdolagas tomorrow with my wonderful, free, purslane--FULL of Omega 3s.

The short answer is that Omega-3s are a fat, so they are found specifically in the fat of animals, which can be mixed in with the "meat" (think a marbled steak or fatty fish like salmon where you can't really separate out the protein part of the fillet from the fat without destroying the whole thing). Whether or not a particular fish serving has the Omega-3 you're looking for depends on how it lived its life.
Omega-3s are found in any animal tissue, including fish, beef, and even insects.
Omega-3 fatty acids are just one variation of a trio of fatty acids that are considered "essential fats" because the human body can't make them - we have to get them from our food. We also have to get an appropriate balance of the 3 (Omega-3, Omega-6, and Omega-9)
Omega-3s have gained a lot of attention in recent years because research has suggested that while Americans get plenty of the other two variants, especially Omega-6, we don't typically get enough Omega-3. This has to do with conventional farming techniques - 100% grass-fed beef has a balance of Omega fatty acids that is appropriate for humans. Conventional (mostly grain-fed) beef has way more Omega-6 and not nearly enough Omega-3 for what humans need.
The same issue happens with fish - wild-caught salmon has plenty of Omega-3 available for humans, but farm-raised salmon can often have very little or none.
Pasture-raised hens can produce eggs high in Omega-3 fatty acids as well.
Plant sources typically provide ALA, which is a form of Omega-3 fatty acids that the human body can convert into the other forms it needs (including DHA and EPA). Plant sources include certain seeds and nuts such as chia seeds, flaxseed, and walnuts.
As for the research on Omega-3 supplements, I would be interested to see if the researchers gave the participants controlled prescription sources, or if the participants were self-reporting that they consumed "an Omega-3 supplement". The quality of what's available on the open market is quite mixed. The cholesterol study that prompted all the plant sterol craziness a few years back involved participants taking a prescription supplement that had been tested for quality, quantity, and type of plant sterol, unlike the "heart healthy margarine", etc. that you now see in grocery stores.

Omega 3's are considered an essential nutrient. A requirement that can be easily met by eating a healthy diet.
I'm not sure that popular literature and some doctors have caught up to research on Omega-3 fish oil supplements.
In 2015, a large clinical trial (4,000 patients) followed over a five-year period found that omega-3 supplements did not slow cognitive decline in older persons. Further, in 2018, a review of 80 clinical trials on the subject showed that Omega-3 supplements have "little or no effect" on the risk of cardiovascular events, stroke, or irregular heartbeat.
Fish get their omega 3s from plants! The best plants for getting omega-3 are dark greens, brussel sprouts, walnuts, cauliflower, winter squash, flax seed, etc.. Eat a healthy diet and get all the nutrients your body needs in the form it needs.
Nutritional supplements such as fish oil are sold for their omega 3 benefits. Additionnally, salmon contains fat in the form of the "white stripes" among the golden orange flavorful meat. But i still don't know which has higher concentration of omega 3.
