Sea angels are beautiful creatures but also deadly predators at the same time. They live in the deep sea (660 feet to the bottom of the ocean), around 600 meters (2,000 feet) deep. They live in cold temperatures. Their relatives are sea butterflies, sea slugs, and snails, and they are Invertebrates (animals lacking a backbone) and less than an inch tall. Their food source/diet/prey is the sea butterflies. The predators are jellies, ctenophores, fishes, baleen whales, and birds. They can hide in the sea because of their transparent body in the dark ocean, making them a bit harder to find.
Ocean increasing ocean temperatures leave sea angels with little to eat. They eat sea butterflies. Their shells are made from calcium carbonate. As the chemistry of the ocean changes, less calcite and aragonite are available to animals to build their shells, and this can result in smaller populations of sea butterflies, leaving sea angels with less to eat, and they might need to find another animal to prey on to live.
