What is the best thing to put in a underwater salad?

That's a fun thought experiment! There's no such thing as an underwater salad in the traditional sense, but if we're talking about what you could eat in an underwater environment, here are some fun ideas:

Seaweed & Algae: The obvious choice! Many types of seaweed and algae are edible and packed with nutrients. Think kelp, nori, wakame, and spirulina.

Ocean Vegetables: Consider sea cucumbers, jellyfish (certain species), and even some types of plankton, which are surprisingly nutritious.

Fish & Shellfish: This is a classic underwater protein source. Choose sustainably sourced fish and shellfish for your salad.

Coral Reefs: Coral reefs are often called the "rainforests of the sea" because they support a vast diversity of life. Some coral species are edible and can add a unique flavor to your underwater salad.

Deep Sea Creatures: This might be a bit adventurous, but some deep-sea creatures, like giant isopods, are edible. You'd need to be sure they're safe to eat and avoid any potentially toxic species.

Don't forget the "dressing": You could add a bit of seawater, although it might be a bit salty. Maybe a squeeze of lemon juice from a nearby underwater citrus grove?

Important Considerations:

* Safety: Make sure any underwater food you choose is safe to eat and doesn't contain any toxins or parasites.

* Sustainability: Consider the impact of your food choices on the marine environment.

Ultimately, the best "underwater salad" is one that is delicious, safe, and sustainable!
