White abalones are slow-moving, algae-eating mollusks. Rapid overharvesting since the 1970s has resulted in white abalones becoming the first marine invertebrate listed as endangered on the Endangered Species Act in 2001 . The population is struggling to recover because they need a mate nearby in order to breed—a difficult task with a small and scattered population. A 2010 assessment stated that...Read more

Baleen is the series of fringed plates hanging in their mouths that they use to strain the seawater for food. Baleen was used in a number of consumer products, such as corsets. Here, a researcher examines the baleen from a whale that washed up on the beach. More about the...Read more

Is that fruit swimming in the ocean? Well it may look like fruit, but it's actually a pineapplefish ( Cleidopus gloriamaris ).

These newly hatched arrow squid larvae ( Doryteuthis plei ) are each tinier than the head a pin. Free from their yolk sac, they will drift with the current out to sea as zooplankton. Many animals eat zooplankton, so few will survive to adulthood and to reproduce themselves.Read more

By drifting in the blackwater in a scuba suit just under the surface, some 60 to 70 feet below, divers can film some of these bizarre animals.

An estimated 1.8 billion people will suffer from water scarcity by 2025. Looking for sources of water is becoming important and with oceans containing around 97% of Earth’s water, it would be nice if we could make use of its bounty. The ocean is incredibly salty because the natural erosion of rocks washes salts into the ocean, where they dissolve into the seawater. Humans are very sensitive to...Read more
