Hobgoblin from the depths

Seen from below, a creature between terrifying and unbelievable appears to fly by, with huge eyes and outstretched claws holding a clear parachute. Actually an inch long, this oceanic animal is a predatory relative of beach fleas called Phronima with a grisly habit: eating out the insides of gelatinous animals such as salps to make a transparent barrel for a shelter. This female, photographed during a 2006 voyage to Antarctica to study plankton ecology, carries pinkish eggs while grasping her barrel. When the eggs hatch, she will incubate her babies in the barrel.
