Halophyte plants use a sacrificial salt leaf. They concentrate excess salt into a specific leaf, then cut it loose when it reaches capacity.

The mammalian equivalent would likely be salt hairs.

Wow interesting. Are there any edible such plants? Then their salt leaves could be used as natural seasoning

Salicornia bigelovii is an amaranth, sometimes known as "sea beans", "sea asparagus", or "samphire greens". It is edible, and the seeds are an oil crop. It can grow at 200% the mean salinity of ocean water.

It can grow in seawater, brackish water, or effluent from other agriculture or aquaculture. We should be growing more of it.

Atriplex genus are amaranths called "saltbush"; many are edible directly or usable as livestock forage. Atriplex hortensis is a leaf vegetable, like spinach, often paired with sorrel.

Tetragonia tetragonoides is "sea spinach" and has been cultivated as a leaf vegetable.

Attalea speciosa is an oil palm tree.

Anemopsis californica or "yerba mansa" is used as a medicinal herb.

Oh wow, of course! I know salicorne from vacations in France. Totally forgot about it.
