Squids, like other cephalopods, have a unique anatomy that includes a branchial heart located near their brain, in their head

This is distinct from most other animals, which have their hearts located in their chests

Squids actually have three hearts. Two of the hearts are branchial hearts, which pump blood to the squid's gills, while the third is a systemic heart that pumps blood to the rest of the squid's body

The branchial heart near the brain ensures that the squid's brain and eyes receive a constant supply of oxygen, which is essential for their survival

Squids have a high metabolism, which requires a lot of oxygen. Their unique heart arrangement helps to meet this demand

Squids are fast swimmers, and their powerful hearts help to pump blood to their muscles, allowing them to move quickly through the water

Squids have relatively large brains compared to their body size. The branchial heart near the brain helps to supply the brain with oxygen

Squids are known for their complex behaviour, including communication, problem-solving, and social interactions. Their unique heart arrangement may help to support this complex behaviour

The unique heart arrangement of squids may have provided an evolutionary advantage, allowing them to thrive in their environment
