The Sea’s Strangest Square Mile

Sit back and let your eyes soak up this goggle-fogging journey to the Lembeh Strait near Indonesia by Shark Bay Films. It’s known as one of the richest homes of odd coral reef creatures on Earth.

More animals with camouflage skills are hiding in the archives. Plus, cephalopods, because.

What can we learn from a tiny seahorse that might help us make stronger robotics or armor in the future? UCSD Materials Science Ph.D. student Michael Porter explains what his team has learned about the flexible structure of a seahorse’s prehensile tail.

There are more fish swimming, including these sea dragons and other syngnathidae, in the archives.

Swim down under Hawaiian waters with PBS Digital Studios’ UnderH20 team to watch how lava from the rumbling Kilauea crater bursts into the Pacific Ocean, and then quickly cools to form what’s called pillow lava.

Another underwater adventure in the archives: diving under a lake covered with Antarctic ice.

Like an elusive, caped creature in the ocean, a female blanket octopus glides through the water. We know this video is of a female of the species because she is around two meters (6.6 feet) long. In contrast, the male blanket octopus is less than 3 centimeters wide. Yes, centimeters!

Differences in males and females of a species is called sexual dimorphism, and can include size, coloring or ornamentation, form or structure, and behavior. A few examples of this include peacocks, peacock spiders, birds of paradise, lions, elk, and even humans. The BBC is a good start for further viewing.
