Elves are immortal, and remain unwearied with age. They can recover from wounds which would be fatal to a Man, but can be killed in battle. Spirits of dead Elves go to the Halls of Mandos in Valinor.
After Aragorn's death, Legolas made a ship in Ithilien and left Middle-earth to go over the sea. His strong friendship with Gimli prompted Legolas to invite him to accompany him to the Undying Lands; making him the first and only Dwarf to do so. He was never seen again in Middle-earth.

Who does Legolas marry?
Lord of the Rings: Legolas Basically Married Gimli. Legolas and Gimli's relationship is strong in The Lord of the Rings, even though it wasn't explicitly romantic in Tolkien's source material. The members of the Fellowship in The Lord of the Rings forge an unbreakable bond while on their mission to destroy the One Ring ...
So much so, in fact, that he never shows any interest in romance ever again. He never even talks about romance in The Lord of The Rings trilogy. While he became averse to falling in love, the son of Thranduil did not become loveless. Legolas traded romance for strong, loving companionship among friends.
He died at the age of 210, after 122 years as king. The graves of the hobbits Merry and Pippin (who had died in Gondor 58 years earlier) were set beside his. He was succeeded on the throne by his son, Eldarion. Arwen, heartbroken by the loss of her husband, died shortly afterwards in Lothlórien.
Unlike the race of Men, they didn't physically age. They just remained constant -- an unchanging incarnation of their eternal form. Thus, once they were 100 years old, they looked the same for the rest of their lives. While Elves were done growing at 100 years old, they never stopped growing mentally.
Are any of the elves who first awoke Cuiviénen still around by the time of LOTR? The oldest elf in LoTR is Círdan the Shipwright, the oldest Elf still remaining in Middle-Earth, who appears at the end of Return of the King to sail to Valinor.
It is later mentioned that Tauriel is a talented warrior and was therefore made leader of the Mirkwood border guards. Legolas, the son of Mirkwood's Elven king Thranduil, is indicated to be attracted to her, but as she is a lowly Silvan Elf, she does not believe herself worthy of him.
No, Legolas was a Silvan Elf whereas Galadriel was Noldorin. It is possible that Legolas was related to some of the Elves of Lothlorien, but not to Galadriel.
That said, the people behind the “official movie guide” for The Lord of the Rings list Legolas as being born in the year 87 of the Third Age of Middle-earth, which makes him some 2,931 years old around the time of the War of the Ring, which happened over 3,000 years into the Third Age of Middle-earth.
Only Legolas still stepped as lightly as ever, his feet hardly seeming to press the grass, leaving no footprints as he passed; but in the waybread of the Elves he found all the sustenance that he needed, and he could sleep, if sleep it could be called by Men, resting his mind in the strange paths of elvish dreams, even ...
Eventually, Legolas came to Ithilien with some of his people, with his father's leave, to live out his remaining time in Middle-earth helping to restore the devastatedforests of that war-ravaged land.
The wizards true form are of course as Maiar spirits - and thus are not mortal, nor are they immortal - they are eternal and divine - essentially angels. In this sense, their lifespan is infinite, they will endure until the end of Arda, and then even beyond this.
Galadriel leaves Middle-earth in TA (Third Age) 3021 when she is around 8,000 years old. Given that the events of The Rings of Power take place before the Third Age, she's around 5,000 years old in the show. This is also corroborated by her birth date in Valinor of 1362 in the "Years of the Trees".
Isildur's father was Elendil, descended from Elros, founder of the Kingdom of Númenor. Since Elros was half-elven, from the marriage of Beren to the elf Lúthien, he and his descendants enjoyed much longer life than other men.
In one of the texts in The Nature of Middle-Earth, Tolkien writes that Eldarion would have lived 120 years, and that his descendants would have lived longish life spans for normal humans (about 80–85 years) but not more than that.
However, he does not possess the ability to live forever, and he cannot choose to be mortal or immortal like Arwen, the half-Elf he loves and eventually claims as his wife. Because Aragorn is mortal and Arwen chose to remain in Gondor and become mortal, their son, Eldarion, is mortal as well, despite his Elven lineage.
It is believed that after Kili dies, Tauriel becomes a lone rider and never loves again, she was so broken by the experience of losing him. Their love was real, and it was as strong as any other Middle Earth romance story. But this romance doesn't appear in the original book, so where did it come from?
However, a specific scene in The Lord of the Rings has led fans to theorize that Frodo and Legolas didn't talk, not because of time, but because the hobbit didn't know Legolas' name (and was too embarrassed to ask).
