The world's second largest filter feeding shark is basking shark . It is the largest whale shark filter feeding shark and the world's second largest filter feeding shark.
The bass shark, also known as the elephant dragon or elephant shark, is the world's second largest filter feeding shark after the whale shark.
Based sharks are sociable animals, usually as many as hundreds of tails parade slowly on the water surface.
Sometimes they will dorsal fin will expose the water surface, or turn over to dry the belly.
Feeding on plankton invertebrates, small fish or fish eggs, it has seasonal migration habits.
Bass sharks generally live in continental sheds and island sheds on the outer sea.
But the activities of basking sharks often occur on the shore, the periphery of the intertidal zone, or the inner bay.
There is a saying in rural Sichuan that says "Pig, four dogs, three cats carry the load".
This sentence means that the pregnancy cycle of a pig is 4 months, the pregnancy cycle of a dog is three months, and the pregnancy cycle of a cat is two months.
Do you know that the bass shark is not only the world's second largest filter feeding shark, but also the world's longest pregnancy cycle.
In fact, in sharks, their pregnancy cycle is much longer than other organisms.
Especially the bass shark.
The pregnancy cycle of a bass shark is three years and Monday, and some can last up to four years.
As a result of such a low reproduction rate, in today's marine environment, basking sharks appear in people's sights very little.
Especially in the past decade, the situation has become less and less rare. The sharks that appear are already on the verge of extinction.
