How big is the Manta Rays? The length of the Manta Ray is up to 7.6 meters (25 ft) with weight as much as 1,300 kilograms (3,000 lbs).

What its cool ability? Manta rays have the largest brains of approximately 32,000 fish species (source). They show intelligent behavior like coordinated feeding and easily get social with human swimmers and scuba divers. Manta rays are not dangerous and gentle swimmers, but do not touch them. Human touch will remove their protective, slime coating from their skin and it will hurt them. Manta rays’ tails do not have spikes like the String rays.

How big is the Mola-Mola? It is the heaviest of all the bony fish! While its size could reach to four meters (14 ft), its weight in between 247 and 2,000 kg (545–4400 lbs).

What its cool ability? They eat jellyfish! Plus they are deep divers up to 100–200 meters depths (328 to 656 ft) and after the deep diving, the mola-mola does the sunbathing to rewarm its body. Don’t be surprise to see the mola-mola floating on the sea surface, it is not dying but they are sunbathing 😀


Whale Sharks

However, with average weight of 20 tons, the shark has a very powerful tail that could caused serious injury if get smashed at!

What its cool ability?  A whale shark can filter through more than 6000 liters of water per hour and its average life span is 100 to 150 years old!

  1. Wow they are awesome, it’s great to find out about new up and coming companies. I love the mocha bag tag. But all the big four are super cool. Thanks for sharing. Alex

  2. Wow….such great insights! Not sure why but your posts do not seem to be coming on my WP reader…bummed that I missed the earlier ones. Going to read them now 🙂

  3. What a GREAT post, so fascinating and as always, so information. Of these “Favourite Big Four”, it is SO hard to choose. I love them all. Been always been one to root for the underdog and am going to go with the Mola-Mola. I have never heard of them before. And what a cool ability to dive to such deep depths.. It really would an amazing sight to see them sunbathing on the surface.

    Thank you Indah for this post, and to Dive Inspire for your great work in the diving community! 🙂


  4. It would really be a super amazing experience if we see those big 4 in the wild. We have a whale shark watching attraction here in Cebu, but we don’t support it because of its non-sustainable, non-eco-friendly method.
