  1. 💁🏻‍♀️ TIL: 🛸🌊 A #NOAA #ROV explores abyssal plains near the #CookIslands in the #SouthPacific, mapping the deep seafloor and #water column with sensors while live streaming nearly daily through August 13. Divers have already spotted carnivorous #sponges that capture small #crustaceans, a surprising find for habitats once thought sparse.

  2. Chondrocladia Sponge

    "A bizarre and rarely-seen carnivorous #DeepSea sponge, Chondrocladia lampadiglobus (colloquially known as the ping pong tree sponge) can be seen growing on stalks anchored in the sediment of the #abyssal #ocean... They have a modified version of the internal water flow system found in shallow-water #sponges, but they use it to inflate the round balloon-like structures that capture prey (usually small #crustaceans) using hooked spicules."

  3. #Canada moves to protect #CoralReef that scientists say ‘shouldn’t exist’

    Discovery was made after #FirstNations tipped off #ecologists about groups of fish gathering in a fjord off #BritishColumbia

    "On the last of nearly 20 dives, the team made a startling discovery – one that has only recently been made public.

    "'When we started to see the living corals, everyone was in doubt,' says Cherisse Du Preez, head of the deep-sea ecology program at Fisheries and Oceans Canada. 'Then, when we saw the expansive fields of coral in front of us, everybody just let loose. There were a lot of pure human emotions.'

    "Despite existing in absolute darkness, the lights of the submersible captured the rich pinks, yellows and purples of the #corals and #sponges.

    "The following year, the team mapped #LopheliaReef, or #q̓áuc̓íwísuxv, as it has been named by the #Kitasoo Xai’xais and #Heiltsuk First Nations. It is the country’s only known living coral reef.

    "The discovery marks the latest in a string of instances in which Indigenous knowledge has directed researchers to areas of scientific or historic importance. More than a decade ago, #Inuk oral historian Louie Kamookak compared #Inuit stories with explorers’ logbooks and journals to help locate Sir John Franklin’s lost ships, HMS Erebus and HMS Terror. In 2014, divers located the wreck of the Erebus in a spot Kamookak suggested they search, and using his directions found the Terror two years later."
