The animal with the smallest heart is the fairyfly.
Here's a breakdown:
- Fairyflies: These tiny insects, some species of which measure only 0.006 inches in length, possess the smallest known hearts.
- Microscopic Hearts: Due to their minute size, the hearts of fairyflies are only visible under a microscope.
- Simple Structure: The fairyfly's heart is essentially a tube running along its back.
- Species Example: One notable example is Tinkerbella nana, a newly discovered species of fairyfly in Costa Rica, which exemplifies these characteristics.
