Thanks so much! It's a lot like taking pictures of a zipper.

Actually dolphins can detect all primary tastes, sea lions on the other had it appears they have issues tasting salty and sweet tastes.
Results of a taste study: "Results indicate this bottlenose dolphin detected the four primary tastes in the solutions tested. The California sea lion detected salty and sour tastes and the bitter taste of quinine monohydrochloride dihydrate (QMD) solutions, but did not detect the bitter taste of quinine sulfate or the sweet taste of surose."

Dolphins can actually be quite picky with fish about the kinds they will and won't eat.

Oh, that's interesting! I never knew that, actually. Even though they can taste all primary tastes, aren't they less sensitive to (some) tastes than we are? Because I can imagine it being extremely annoying to constantly swim with that salty taste in your mouth. On the other hand, they might just be used to it

The dolphin tasted the difference between all of them. How much or what they actually taste will have to wait till we can talk to them, all we know is that they can taste the difference.
The sea lion on the other hand "did not detect the bitter taste of quinine sulfate or the sweet taste of surose."
"The bottlenose dolphin's taste acuity is roughly an order of mangnitude less then humans. The CA sea lion's threshold for sodium chloride is 20 times the human standard, but the threshold for citric acid is nearly the same. Seawater is isotonic with a 0.6 M sodium chlodride solution. Our results with sodium chloride solutions indicate that sea lions can detect salt solutions of even lower salinity."
Page 453 has the chart of how much of the solution was needed for humans, dolphins and sea lions.
