From KQED Quest, the challenges and new research being explored by marine biologists that breed, collect and care for jellyfish and siphonophores at the Monterey Bay Aquarium in California.

Learn more about the diverse family tree of jelly-like creatures in this beautiful HD video from the Aquarium’s Research Institute, or watch more about marine biology.

A preview from The Deep Sea, ep11 of the BBC’s Nature’s Microworlds: 

Steve Backshall takes us to a place few have ever visited - the deep sea. 99 per cent of the space on Earth inhabited by life is under the ocean and almost 90 per cent of this is deeper than a kilometre, a place of perpetual darkness and crushing pressure. Far from being lifeless, the vast inner space of our planet contains an extraordinary array of beautiful and bizarre creatures, from 40m-long jellyfish to grotesque angler fish and vampire squid. Our journey from the sunlit surface waters to the deepest reaches of the abyss reveals how life persists in such a hostile world. 

Have you seen the robot AquaPenguin, from the Festo HQ team’s Bionic Learning Network in Germany? It comes complete with glowing robot eyes!

Other great videos to check out from Festo: AquaRay, AirRay, AirPenguin, AirJelly, and their aqua jellyfish: 

Nuts and bolt details are described in this video on engineeringtv.com.

From the team that brought us The Secret Life of Plankton and The Plankton Chronicles comes this wonderful TEDEd video from their amazing microscopic footage, re-created to explain How Life Begins in the Deep Ocean:

Where do squid, jellyfish and other sea creatures begin life? The story of a sea urchin reveals a stunningly beautiful saga of fertilization, development and growth in the ocean depths.

from TEDEd.

Don’t adjust your sound as this video has none, but wow, does it have a picture! This is a deepstaria enigmatica, a deep-sea jellyfish that was caught by a remotely operated underwater camera about 5000 feet (1500 m) down. Wikipedia places them “in Antarctic and near-Antarctic seas” and puts their size at “approx. 60 cm” (or almost 2 feet) wide. Impressive, nature. Impressive.
