This bright orange Ctenophore was spotted during the Hidden Ocean 2016: Chukchi Borderlands expedition in the Arctic.

Using a combination of high-definition video footage and a collected sample, scientists were able to determine that this ctenophore is likely a new species.

Deep Sea Corals

While thinking of corals may conjure up images of sunny, warm, tropical reefs, did you know that over half of all known coral species are actually found in deep, dark waters where temperatures range from 4-12 degrees Celsius (39-54 degrees Fahrenheit)? #CoralsWeek

Photo: In 2012, scientists investigating deepwater canyons off the coasts of Virginia and Maryland discovered, for the first time, Lophelia colonies in the area. This discovery filled a gap in scientists’ knowledge of the distribution of this important deep-sea coral species.

A deep-sea Chimaera. Chimaerae are most closely related to sharks, although their evolutionary lineage branched off from sharks nearly 400 million years ago, and they have remained an isolated group ever since. Like sharks, chimaera’s are cartilaginous and have no real bones. The lateral lines running across this chimaera are mechano-receptors that detect pressure waves (just like ears). The dotted-looking lines on the frontal portion of the face (near the mouth) are ampullae de lorenzini and they detect perturbations in electrical fields generated by living organisms.

A scaleworm, 5-cm (2 in) in length, crawls along the underside of a 60-cm (2 ft) holothurian, or sea cucumber.

Seen while exploring at a depth of ~1,525 meters (5,000 feet) in Indonesian waters, at a site referred to “Baruna Jaya IV - Site 1” on August 1, 2010.

What are the red dots on this deep sea Chimera (aka ratfish)?! Here’s a little primer for our fellow ocean explorers as we prepare to begin diving again…

When watching the live video feeds, you’ll often see two red dots. These laser points are 10 centimeters (about 4 inches) apart and scientists use them to help determine the sizes of things they are seeing.

During the Hohonu Moana:

Exploring Deep Waters off Hawai’i expedition, scientists observed at least two types of cusk eels of the genus Diplacanthopoma.

Prior to these observations, the Hawaiian Diplacanthopoma was only known from floating specimens, apparently killed by underwater lava flows – these fish had never before been seen alive and we knew nothing about their ecology.

Though there is still much to uncover, we now know more about these deep-sea fish…every discovery brings us closer to understanding – and being able to better protect – life in the deep sea.
