Crocodiles are dinosaurs. Why can they live to this day?

To tell the truth, I'm not afraid of jokes. I always thought crocodiles were descendants of dinosaurs. Because of the crocodile's appearance and living habits, it feels particularly like a dinosaur. In addition, many media have reported that crocodiles are extremely ancient creatures on the earth, so I always subconsciously think that when dinosaurs became extinct, those dinosaurs that escaped into the water evolved into crocodiles. But after consulting the information, I found that crocodiles on the earth could compete with dinosaurs on the same stage.

In my opinion, crocodiles can avoid the initial asteroid impact because they were born in the water? Due to the influence of planets, many geological disasters have occurred on the earth. In particular, the volcanic ash produced by volcanic eruption directly covered the earth. As a result, many plants cannot carry out photosynthesis, and most of them are terrestrial organisms. So it directly cut off the food chain on which dinosaurs lived, but dinosaurs did not suddenly become extinct. After years of hunger, dinosaurs became extinct.

Crocodiles living in water actually suffer much less changes than dinosaurs, because many microorganisms in water do not live directly through microorganisms. In addition, we can now see the way of artificial feeding, and we can also feed crocodiles, which shows that crocodiles have strong adaptability. On the other hand, crocodiles are cold-blooded animals, and they always lie there to rest when they have nothing to do.

This has caused the crocodile's metabolism to be much smaller than that of the dinosaur, and it didn't eat much naturally. And in the case of food shortage, crocodiles will also cooperate with their companions to hunt. When they catch some large prey, they will share the fruits of their labor. But at this point, they are much better than dinosaurs. I think when dinosaurs were forced into the water, they were probably attacked by crocodiles. Many crocodiles have become the staple food of crocodiles during this evolution.
