If aliens landed on our planet tomorrow, capable of breathing in any condition, they’d likely find the depths of our oceans the most intriguing and relatable aspects of this planet. As land dwellers, however, we’ve only begun to explore the depths of the underwater world.
In the spirit of summer and thoughts of the sea, we went on an internal expedition for images of the underwater world (we think) we know of, in search of the most intriguing creatures and deep-sea visions. Below, you’ll find some of our most beautiful and unique picks, paired with random facts — because the water is teeming with them.
1. The Sea Urchin
These fascinating “underwater hedgehogs” are able to move around via tiny tubes that function as their feet. Hydraulic pressure and a water vascular system work in conjunction to pump water in and out of those tubes — hence, mobility!
2. The Sea Slug
These colorful sea-floor dwellers emit sounds that are audible by humans. According to one professor, they sound like a steel wire hitting the side of a glass jar. We can only assume that these sounds are made in an effort to communicate or fend off predators.
