Answer: What is the longest living vertebrate on Earth?

The Question: What is the longest living vertebrate on Earth?

Galapagos giant tortoise
Greenland shark
Longfin eel
Bowhead whale

Greenland sharks are one of the largest cartilaginous fishes (fish whose skeletons are made of cartilage) in the ocean and the longest-lived vertebrate on Earth. They can grow to be 23 feet in length and weigh 2260 pounds. Scientists aren’t completely certain how long they can live for, but radiocarbon dating suggests that the oldest in the species may be over 500 years old. They are found in cold-water environments in the Arctic and North Atlantic ocean, but because they are seldom encountered in the wild, we still don’t know very much about them.

The correct answer is Greenland shark.
