Researchers from the University of Tsukuba find that planktonic sea urchin larvae exhibit a cilia-based response and swim backward when exposed to strong irradiation In a study published this month in ...

The larvae of sea urchin start swimming backwards on exposure to strong light — a finding that fills in a missing piece in how light-responsive systems developed in animals. Almost all living ...

As planktonic organisms the larvae of the marine annelid Platynereis swim freely in the open water. They move by activity of their cilia, thousands of tiny hair-like structures forming a band along ...

For many ocean invertebrates, the first stage of life occurs as tiny larvae in the plankton. The toughness of the planktonic larval life has caused many scientists to wax poetically, as we tend to do ...

The eyes of some marine-dwelling creatures have evolved to act like a "depth gauge", allowing these creatures to swim in the open ocean at a certain depth . Pioneering new research, carried out by a ...

Under the microscope, sea water reveals the larval stages of little-known marine creatures called phoronids (horseshoe worms), but finding their parents is another story. Although such fanciful larvae ...

A Queensland University of Technology (QUT) team led by Southern Cross University's Professor Peter Harrison has developed the "LarvalBot" underwater robot that, for the first time, has succeeded in ...

GLOBAL warming is not the only environmental change that is being wrought by rising emissions of carbon dioxide. This gas, acidic when dissolved in water, is also lowering the pH of the world’s sea ...

Researchers found that sea urchin larvae exhibited ciliary responses to strong photoirradiation by swimming backward. As ciliary responses are difficult to detect in deuterostomes because they may be ...
