The sea is, without a doubt, one of the richest environments in biodiversity, however, we are not always able to observe everything easily. This is because most of the species that inhabit the oceans they belong to the dark depths of the waters, to which the human being has almost no access.

sea anemone
Anemones are beings of extreme complexity and beauty, and draw attention for their colorful bristles that remind us of tentacles. In fact, this peculiarity makes them more interesting, since it is through their “tentacles” that they manage to capture their prey. After all, anemones are known for their ability to neutralize their victim through neurotoxins, which allows them to defend themselves and get food. Furthermore, they are beings of asexual reproduction and only want to surface when it's night.
Australian Jellyfish
This species of jellyfish lives in the waters of Australia and belongs to the Cubozoa group. It is certainly one of the most beautiful marine species, but it is also among the most dangerous. That's because the Australian jellyfish has a lethal venom that directly attacks the nervous system, heart and skin cells. Thus, their victims tend to die even before getting out of the water. It's a good thing they only appear on the surface at night, as during the day they remain reclusive in the darkness of the seas.
sea butterfly
Finally, we have this other species that only gives us the air of grace when night comes. In this case, what catches our attention is the beauty of its transparency and also its capacity for luminosity. After all, sea butterflies have a kind of incandescent lamp in the center of their body, and this allows them to glow in the dark. Furthermore, note that the structure of its body resembles the wings of a butterfly, and this similarity is the reason for its name.
