Would you mess with a 40-tonne humpback whale?
In this image, not only does the diver seem dangerously close to a 40-tonne humpback whale (Megaptera novaeangliae), this one’s also a female whose calf is not far behind. And speaking of gigantic proportions: Mara, here pictured in December 2007, was on a journey from Polynesia, where her calf Kell was born, to Antarctica, making her annual summer migration to feeding grounds thousands of miles away.

This diver in Vava’u, Tonga got lucky filming an inquisitive humpback whale baby. Humpback whale calves weigh one to two tons when born and are around 1.5 m long. For them to gain about 100 lbs a day, the mother has to express about 100 liters of her rich, fatty milk daily.
Whales do seem to eat up nautical miles like airplanes do sky miles. Humpback whales for example travel some 25,000 km each year when migrating! They can be found in all of the world’s oceans and do come quite close to the shore in some instances.

As larger whales of the baleen whale species, humpback whales can reach lengths of 12–16 m (39–52 ft) and weights of 36 tonnes (79,000 lb) or more. Like a giant, built-in toothbrush, baleen whales have long strips of baleen for filtering food from the water rather than teeth.

Not been spotted yet…
Here, a diver takes a closer look at a whale shark (Rhincodon thypus). If you’re wondering what that is on its fin – those are smaller fish, catching a ride!

Whale sharks are not mammals but the largest living fish species, reaching lengths up to 13 m (42 ft) and weights of 22 tonnes (47,000 lb), though according to unconfirmed claims, larger whale sharks are said to have been spotted. But then, if faced with one of these giants, would you really care whether it’s 13 m or 15 m? Huge is huge!

Whale sharks are gentle giants and said to be the most people-friendly of the lot. So friendly in fact, that a Laguna Beach surfer got the shock of his life in September 2004 when what he thought was a wave turned out to be one: “All of a sudden I just felt, wow, this huge noise and bump,” said [Spyros] Vamvas, “and it lifted my board up. I’m looking down, and there’s just swirling water and I see barnacles on the back of the whale. I’m used to dolphins. This was different. It was huge.”

And those who believe that large animals need to feed on other large animals are proven wrong by the whale shark. Its distinctive broad mouth serves the purpose of taking in large quantities of small organisms like plankton, microscopic plants and schools of small fish.
The species originated some 60 million years ago and their conservation status today is classified as vulnerable. Whale sharks can be found in the tropical and warmer regions of all the world’s oceans and live for about 70 years.
