Time-lapse photography provides a view of the seafloor at timescales that make it possible to recognize behaviors and activity of often slow-moving abyssal fauna. Most behavioral studies have focused on mobile animals; sessile benthic fauna have largely been overlooked. We combed through 30 years...

Background: The Wnt signaling pathway is uniquely metazoan and used in many processes during development, including the formation of polarity and body axes. In sponges, one of the earliest diverging animal groups, Wnt pathway genes have diverse expression patterns in different groups including...
