Scientists have discovered a meat-eating sea sponge like a harp living in deep waters off the coast of California.
The odd-looking creature, dubbed a "Harp Sponge", uses its numerous long string-like limbs to catch prey.
A team of researchers from Monterey Bay Research Aquarium Institute in California found the sponges living roughly 3km below the surface of the ocean in 2000 but only published their findings recently.
"We were just amazed. No one has ever seen this animal with their own eyes before," said Lonny Lundsten, a biologist from the institute who was one of the first to spot the sponges.
After collecting two sponges and observing the animals in the ocean researchers concluded they were a new species and they were given the scientific name Chondrocladia lyra.
The sponges' long limbs are covered with Velcro-like barbed hooks.
They eat by covering their catch with a thin membrane before digesting it.
Scientists first discovered carnivorous sponges 20 years ago but they have proven difficult to observe as most live in the deep ocean.
