Data from: Behaviors of sessile benthic animals in the abyssal northeast Pacific Ocean
2020-01-07
Kahn, Amanda S., Pennelly, Clark W., McGill, Paul R., Leys, Sally P.
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...

Suspension feeders are an important component of carbon exchange between the water column and the seafloor, a process called pelagic-benthic coupling. Sponges (Phylum Porifera) are filter feeders that consume especially small particles. They eat bacteria, which are inaccessible to most other...

Ephydatia muelleri Trinity transcriptome
2017-11-08
ABSTRACT 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...

Evolution of the sponge body plan: Wnt and the development of polarity in freshwater sponges
DownloadSpring 2014
Body polarity is a fundamental aspect of all multicellular organisms. Metazoans – animals – are monophyletic, but is body polarity homologous among all phyla? Sponges are considered to have branched off first from other animals and therefore studies of polarity formation in the simple sponge body...

Evolutionary origins of sensation in metazoans: functional evidence for a new sensory organ in sponges
Download2014-02-11
Background One of the hallmarks of multicellular organisms is the ability of their cells to trigger responses to the environment in a coordinated manner. In recent years primary cilia have been shown to be present as ‘antennae’ on almost all animal cells, and are involved in cell-to-cell...

The goal of this guide is to derive a better understanding of the biodiversity of sponges across the eastern Canadian Arctic. Specimens were collected during research cruises aboard the Canadian Coast Guard Ship (CCGS) Amundsen in October 2015, July 2016 and July 2017. Collection sites were...
