The 25-foot humpback whale that has been grounded on a sandbar in Moriches Bay for nearly a week was euthanized Wednesday.

Officials killed the sea mammal after numerous failed attempts to free it from the sandbar, where it has been thrashing around since the weekend, according to Gothamist.

The whale was first spotted in the Long Island area last week, but made its way into the shallow waters on Saturday.

Biologists went out on a boat Sunday to examine the baby whale. They used the boat to create waves that they hoped would help it escape, but were ultimately unsuccessful.
