The average initial HR for all 31 ants was 53.5 beats per minute (Table 1). Winter ants tended to have lower HR and Argentine ants tended to have higher HR, but heart rates did not differ between species (F2,28 = 2.77, P = 0.079).
Are ants beating their hearts?
They lack a proper heart, but have a pumping organ called the dorsal aorta that pumps blood toward the head, achieving a small electric current. Unlike blood, blood lymph does not carry oxygen. Therefore, ants (and all other insects) are completely lung-deficient.
Do ants have a brain?
Each ant's brain is simple and contains about 250,000 neurons compared to the billions of humans. However, ant colonies have a collective brain that is about the same size as many mammals. Some speculate that the entire colony may have emotions.
Do ants feel sad?
No. Individual ants are very primitive. They are at the level of a simple stimulus response. They don't have anything similar to the level of emotion that humans have, so they don't get depressed in the normal sense of the word.
