Deep water explorations near the Galapagos Islands that took place earlier in June unveiled underwater species never seen before, a video posted to a social media website showed.

Scientists studying biological, geological and archaeological sites along the Galapagos hydrothermal vents managed to capture the moment the unusual sea creatures swam by a submarine positioned in the Pacific Ocean.

Another video showed explorations taking place near the Gulf of Mexico on 28 May, where more creatures, such as rare jellyfish species, were spotted.

Scientists leading the exploration group said that a variety of seafloor habitats from the ocean's upper slopes and lower slopes, including coral habitats, hydrocarbon seeps and mud volcanoes, were analysed.

After the Galapagos, the scientists said they expect to explore the Californian coast and head up to British Columbia, an area which has rarely been surveyed by scientists.
