The ocean’s bizarre hydraulic machines are powered by seawaterImagine an animal with no centralized brain that moves using a literal plumbing system. Echinoderms—like sea stars and urchins—don't use blood vessels to circulate nutrients. Inst…
The complex biological engineering behind the sea star's body planThis 1987 documentary explores the sophisticated anatomy of echinoderms. It reveals how these marine organisms have evolved specialized body structures to master the fundamental r…
The hidden plumbing and 3D puzzles of our closest invertebrate relativesEchinoderms are more than just beachside curiosities; they are the invertebrates most closely related to humans. From deep-sea predators to towering prehistoric lilies, these anim…
The basket star is a deep-sea marvel with arms that mimic a mythical monsterBasket stars are complex echinoderms known for their intricately branched arms. While some species dwell in the deep sea, others emerge at night on tropical reefs. These creatures…
The pillow-shaped sea star that defies the classic five-pointed star silhouetteMost sea stars evoke images of slender, radiating arms, but the genus Culcita takes a different approach. These plump, pentagonal creatures look more like discarded cushions than …
The blue sea star that can grow a new body from a single armThe Linckia laevigata, or blue star, is a striking inhabitant of tropical Indo-Pacific reefs. Beyond its vibrant color, this sea star possesses remarkable regenerative powers, cap…- When danger strikes, these flat sea urchins clone themselves to survive the threatSand dollars are more than just bleached beach souvenirs. These burrowing echinoderms possess a remarkable survival mechanism: when larvae sense the mucus of a predatory fish, the…
- The deep-sea pig that walks on tube feet across the ocean floorMeet the sea pig, a translucent, balloon-like creature that roams the abyssal plains. Unlike most sea cucumbers, this species uses specialized tube feet to walk across the seafloo…
The sea apple is a colorful, shape-shifting filter feeder that can weaponize its own body.Found in Indo-Pacific waters, the sea apple is a striking sea cucumber that survives by filtering plankton through feathery tentacles. When threatened, this creature can perform a…
Why this deep-purple sea urchin is a secret mirror to human biologyThe purple sea urchin is more than a kelp-devouring resident of the Pacific coast. As a premier model organism, its genome reveals surprising evolutionary links to humans. From sh…
The 'seasquatch' has returned: A lost predator could save California's dying kelp forestsAfter vanishing from California waters a decade ago, the sunflower sea star—a voracious predator essential to kelp forest health—has been rediscovered. This elusive 'seasquatch' o…
The white skeleton you find on the beach is a masterclass in biological engineeringSand dollars are not just beach souvenirs; they are living, fuzzy discs covered in thousands of spines. This video explores how these unique echinoderms have evolved to thrive on …
