[Global Times comprehensive report] "Cuttlefish is nature's true memory champion." According to the British "Times" reported on the 18th, researchers found that cuttlefish can clearly remember the time and place of everything even at the end of their lives.
Researchers reportedly tested the memory of 24 cuttlefish and found that they could accurately remember the fixed time and place of their breakfast and rely on this ability to obtain their favorite foods. Studies say that even with other signs of aging, such as muscle loss and loss of appetite, cuttlefish's ability to "episodic memory" does not decline with age. This is completely different from the situation that humans "forgot what happened yesterday and forgot today", this is because the hippocampus in the human brain degenerates with age, but there is no hippocampus in the cuttlefish brain, and its structure related to learning and memory is a "vertical lobe", so memory is not affected by age.
The researchers suspect that cuttlefish will even use this ability to "cast a wide net to find objects." It is reported that cuttlefish only begin to breed near the end of their lives, so remembering your mating partner can avoid not returning to the same partner. This allows them to spread their genes as widely as possible. in Roche
