In August 2022, a navally trained bottlenose dolphin received a lot of attention from many biologists in the United States, because the bottlenose dolphin had strange behavior and suddenly became extremely interested in the yellow-bellied sea snake in the ocean, eating eight yellow-bellied sea snakes in one day.
The bottlenose dolphin is fitted with a special strap, and a camera is installed on the left side of the strap, which can be used to track and study the dolphin's behavior, and the camera records the whole process of the bottlenose dolphin eating fish and eating the yellow-bellied sea snake.
According to the footage taken by the GoPro camera, bottlenose dolphins swim rapidly in the light green waters, visible distances of less than 20 meters, dolphins sometimes surface, sometimes sink into the water, the speed is incredible, and humans are not at all the same level, dolphin swimming speed is as fast as 50 kilometers per hour.
Soon, a yellow-bellied sea snake appeared in front of it, and the bottlenose dolphin swallowed the yellow-bellied sea snake without hesitation, from discovery to swallowing, the whole process was less than two seconds, you ate it, and at the moment of eating, the bottlenose dolphin mouth was accompanied by a strange cry, which seemed to be a high-pitched "victory scream".
It can be seen from the expression of the bottlenose dolphin that it seems to enjoy the process of devouring the yellow-bellied sea snake, which is like a person playing a very exciting game, and when it feels very exciting, the mouth naturally emits a strange cry of excitement.
The GoPro footage also shows a situation where bottlenose dolphins don't make a bark when they eat sea fish, and only make weird cries when they devour yellow-bellied sea snakes.
Bottlenose dolphin is a carnivore in the ocean, mainly to sardines, mackerel, mullet, striped fish and other fish as food, occasionally eat crabs, squid, shrimp and other small animals, yellow-bellied sea snake is not in the recipe list, but this bottlenose dolphin is to eat the yellow-bellied sea snake, is it that it wants to seek short-sightedness?
Speaking of water snakes, many people have the impression that water snakes are not poisonous, but the yellow-bellied sea snake living in the ocean is a deadly poisonous snake, which has been ranked tenth in the list of the top ten deadly poisonous snakes in Marvin Costa Rica.
Yellow-bellied sea snake scientific name Pelamis, is a genus of monotypes of venomous snakes in the genus Of the suborder Cobra Sea Snake, with a yellow lower abdomen and a black back, widely distributed in the Indian Ocean and the Pacific Ocean, and the yellow-bellied sea snake generally lives in a wide ocean far from the coast.
The yellow-bellied sea snake venom is highly venomous, ten times more toxic than the Egyptian cobra (Naja haje), which can seriously affect skeletal muscles, neuromuscular paralysis, kidney failure and other symptoms, bottlenose dolphins accidentally bite when swallowing the yellow-bellied sea snake, the consequences are unimaginable.
GoPro cameras recorded that bottlenose dolphins devoured 8 poisonous sea snakes in one day, as long as they were bitten by a yellow-bellied sea snake, bottlenose dolphins are likely to die, so it is a very dangerous thing for dolphins to eat poisonous sea snakes, perhaps this bottlenose dolphin does not realize it.
Once, a seal preyed on a yellow-bellied sea snake and spat it out not long after, which proves that poisoning occurs after ingestion of yellow-bellied sea snake.
But scientists found that this bottlenose dolphin lived strangely well, alive and jumping, and there was no sign of poisoning and injury at all. After watching the video repeatedly, the scientists found that the snakes that the dolphins swallowed were very small, like drinking water, and their heads twitched, sucking the snakes in.
Adult yellow-bellied sea snakes are generally about 70 centimeters in length, while the yellow-bellied sea snakes shown in the video are only about 30 centimeters visually, and scientists suspect that the yellow-bellied sea snakes caught by bottlenose dolphins are newborns and contain low amounts of venom, which is why bottlenose dolphins live strangely well.
The video also shows bottlenose dolphins trying to catch an adult yellow-bellied sea snake with a length of more than 50 centimeters, but the result is unsuccessful, and it is run away by the yellow-bellied sea snake.
The abnormal action of the bottlenose dolphin devouring the poisonous sea snake confuses scientists, in fact, this is likely to be an abnormal psychological activity of animals, just like our human psychology, when you suppress for a long time, you always want to make some abnormal moves to decompress.
This also shows that bottlenose dolphins have rich psychological activities, when it feels depressed, it will use the way of devouring poisonous sea snakes to decompress, but the problem is that yellow-bellied sea snakes are highly venomous, don't lose your life, which is not cost-effective.
In 2021, there was a phenomenon of cattle eating snakes in Australia, cattle are vegetarian animals, and even relished eating snakes, which is simply a strange story, after seeing people come, cattle hurriedly put down snakes and quickly leave the scene, which is the abnormal behavior of animals.
