Velella velella, also known as the "By-the-wind sailor" in English, is a fascinating species of pelagic cnidarian that captures the interest of marine life enthusiasts. It differs from jellyfish in its structure and way of life.

These organisms are often found in groups and float on the ocean's surface, drifting with the marine currents. They have a small triangular sail that enables them to move with the wind. Velella velella is primarily found in the Pacific and Atlantic oceans, although it can be observed in other parts of the world when favorable ocean currents carry them to unusual areas.

One of the peculiarities of Velella velella is its feeding habits. Unlike many other cnidarian species, it does not actively hunt for food. Instead, it mainly feeds on plankton and small marine organisms that it captures using its stinging tentacles.

Regarding its danger to humans, Velella velella is generally considered harmless. Its tentacles are not long enough to reach or harm humans. However, it is important to note that some individuals may be sensitive to cnidarian stings in general, and it is always recommended to avoid direct contact with these creatures due to the possibility of allergic reactions or skin irritations.
