Invert Pictures…TGIM?

Sometimes pictures are too cool to wait for Friday. My friend Tom K. sent these along for my enjoyment and now yours. The first is a close up of the bay scallop, Argopecten irradians, where you can clearly the ring of blue eyes that around the mantle. They are weak but sufficient to detect predators. The second is the red-footed or pygmy sea cucumber, Pentacta pygmaea, common along the Gulf of Mexico.

Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (, a popular ocean-themed blog that has won numerous awards.

  1. I’ll never forget walking through a pile of bay scallops in shallow waters off Beaufort, North Carolina. The scallops were leaping 2-3 feet in the air. They must have seen us coming!
