Which animal has the biggest brain on Earth?
The sperm whale ('Physeter macrocephalus') or cachalot is the largest of the toothed whales and the largest toothed predator.
Mature males average 16 metres (52 ft) in length but some may reach 20.5 metres (67 ft), with the head representing up to one-third of the animal's length. Plunging to 2,250 metres (7,382 ft), it is the second deepest diving mammal, following only the Cuvier's beaked whale.
The sperm whale uses echolocation and vocalization as loud as 230 decibels underwater. It has the largest brain on Earth, more than five times heavier than a human's. Sperm whales can live for more than 60 years.

There is a lot of information about the sperm whale, but nothing about the size of its brain.

Once again, no details on the other options.
OK it wasn't going to be a tiger or an oran-utang, but how much bigger than mine is an elephant's brain?

Since the oceans are on the earth, I'm guessing they qualify as an "on earth" animal. Yes, a mammal is an animal.

Didn't think it was a sea creature. On earth made me think land animal
