Though not technically an animal, this coral is also in need of protection. This branching coral has the fastest growth of all western Atlantic corals. Despite this, its asexual reproduction makes recovery from disease and bleaching very difficult. The Staghorn Coral plays an integral part in the fishery habitats of the Caribbean, but is now critically endangered, as its population has declined up to 98% since 1980.
The Hawksbill sea turtle is a critically endangered sea turtle, the only extant species in the genus Eretmochelys in the family Cheloniidae. The species has a worldwide distribution, with Atlantic and Pacific subspecies. It spends most of its time in shallow lagoons and coral reefs. Human fishing practices threaten E. imbricata populations with extinction. by PaparazSea
The International Union for Conservation of Nature's red list of threatened species – a key indicator of the health of the world’s biodiversity – has been republished, and the giant Australian cuttlefish (Sepia apama) is now a near-threatened species. It is one of more than 1,900 species newly recorded on the list – of the 63,837 species assessed, 19,817 are threatened with extinction, including 41% of amphibians, 33% of reef building corals, 25% of mammals, 13% of birds, and 30% of conifers…
"There is one place on Earth where the impacts of climate change are most profound and yet practically invisible: the oceans. As global emissions soar, the oceans are becoming warmer and more acidic, creating unbearable living conditions for all marine life and threatening precious ecosystems."
A nudibranch eats other poisonous creatures, like corals, anemones, sponges — and occasionally other nudibranches — then processes the toxins and stores them to use later if threatened. Found in warm and cold oceans, nudibranches come in brilliant shades of orange, pink, purple, blue, and yellow, with contrasting stripes, swirls, and squiggles, making this aquatic creature a feast for the eyes. Nudibranches are hermaphroditic, meaning they have both male and female sex organs.
