ALT This beautiful imagery of a larvacean inside of its mucus “house” was captured at a depth of 900 meters (2,950 feet) during the Seascape Alaska 3 expedition. Larvaceans are solitary, free-swimming tunicates that produce these fragile mucus houses to help filter small particles (food) from the water. The larvacean lives inside of its house until the mucus filter becomes clogged, at which point the animal will abandon the house, swimming away to build a new, and unclogged, structure. Given the number of white particles (marine snow) seen in the image, this house was quite full and was vacated while we examined it closer!

ALT While exploring the water column at a depth of 700-meters (2,297-feet) during the 2021 North Atlantic Stepping Stones expedition, we imaged this physonect siphonophore. Although siphonophores may appear to be single organisms, they are actually colonies of many individual hydrozoans (called zooids), each specialized for different functions such as swimming, feeding, reproduction, and defense.
