Gently floating through the ocean like a feather, jellyfish possess the ability to bioluminesce. Their tentacles also serve as a defense mechanism, capable of stinging potential threats.
An accidental “kiss” between a jellyfish and a fish, making it seem like they are sharing a moment. The author captured this moment in the sea off Spain in 2014. (Photo: Joan Costa).
Some small fish are immune to jellyfish stings and can even live parasitically among their tentacles. This not only helps the fish evade predators but also allows them to benefit from the organisms captured by the jellyfish. The image was captured in the Philippines in 2018. (Photo: Lilian Koh).
Under vibrant lights, transparent jellyfish suddenly appear magical with neon blue hues. The image was taken in Australia in 2015. (Photo: Alexandra Cearns).
Jellyfish fossils are hard to find due to their soft tissues leaving no skeletal traces, but remnants have been discovered in sediments dating back 500 million years. The image was taken in Singapore in 2015. (Photo: Froilan Robas).
Under black light, jellyfish glow like radiant orbs filled with electric lights. This magical moment was captured in California, USA, in 2019. (Photo: Kenneth Renk).
Jellyfish come in various colors. They remain beautiful and captivating even in shades of black and white. The photo was taken in China in 2018. (Photo: Benjamin Cooper).

Not far from a developed urban area in Japan, a swarm of spotted jellyfish can be seen in the ocean at the end of summer. The image was taken in 2021. (Photo: Reiko Takahashi).
Above the water, lightning streaks illuminate the night sky. Below the surface, a jellyfish appears to glow in the darkness of the ocean. Many jellyfish produce light through bioluminescence. The image was captured in Vietnam in 2021. (Photo: Phạm Huy Trung).
Jellyfish protect themselves from humans, often those who inadvertently overlook them as they drift to the shore. Jellyfish use their tentacles to sting. The photo was captured in Spain in 2012. (Photo: Albert Olle Callau).

In the waters near Qaruh Island, sailfish feed on remnants from the jellyfish, perhaps searching for small crustaceans living alongside the jellyfish. This moment was captured in Kuwait in 2022. (Photo: Suliman Alatiqi).
