How is light distributed in the ocean?
Munidopsis albatrossae, a blind “squat lobster,” lives at depths up to 2,500 meters. Because there is no light at this depth, they would have little use for eyes and therefore have none. Image...
How does pressure impact animals in the ocean?
Many deep-sea organisms, such as this escape swimmer Benthothuria, lack lungs or gas-filled spaces that make them more susceptible to the intense pressures of the deep ocean. Image courtesy of the NOAA...

Are all corals found in warm, shallow water?
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...
Are glass sponges made of glass?
The primary skeleton of many glass sponges is a network of large spicules that have fused together to form a matrix that defines the overall body shape of the sponge. Image courtesy of...
What is a volcanic "hotspot"?
A hotspot is theorized to form as one of Earth's outer tectonic plates moves over an unusually hot part of the Earth's mantle and large amounts of magma rise up, piercing through...
Are squat lobsters really lobsters?
Squat lobsters look like lobsters, but they are actually more closely related to hermit crabs. They belong to the phylum Arthropoda. The majority of squat lobsters are found in deeper waters and...
