In this world, there are many creatures that seem very strange to us, just like the Okapi introduced to you before Xiaobian, they are very energetic, they can only sleep for 5 minutes a day, but from the appearance point of view, many people will think that it is a combination of zebras and giraffes, in fact, it is the product of nature, today Xiaobian introduced this strange species to everyone, the mouth is like a saw, it looks very domineering!
This creature is called sawfish, flat and long mouth is the most conspicuous, looks like a saw, this fish usually lives in tropical, subtropical shallow water, often in and out of the harbor, estuary, generally adult sawfish, body length of about 5.5 meters, the largest sawfish can even be up to 7 meters, and its most prominent mouth, the length of 1/3 of the total length of the body, the edge has some relatively hard serrated objects, like needles, very tough.
Saw rays that look extremely fierce and domineering, in fact, are not regarded as dangerous fish, but in the ocean world, it is not easy to be bullied fish, just by virtue of that domineering mouth shape, it is enough to make people fearful, under normal circumstances, sawfish will lurk on the bottom of the sea to find prey, their prey objects are usually bottom organisms, when preying, they will use their long mouths to swing hard, the prey in half.
Although it has a natural advantage of the "weapon", but the growth rate of sawfish is extremely slow, although each spawn is only about 10 eggs, but the laying of larvae is very vulnerable to other predatory fish attack, coupled with recent years, sawfish growth environment more and more serious pollution, and human overfishing, today's sawfish has been listed as an endangered species, and has completely disappeared in Europe, what do you think about this?
