Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Vampyroteuthis infernalis Color Differences

Richard E. Young

These photographs of Vampyroteuthis were taken insitu by an ROV of the Monterey Bay Aquarium Research Institute. The two photographs were taken from widely different areas in the North Pacific showing geographic differenences in coloration. The left image is a side view of the vampire in an unusual pose. Note the peculiar nature of the web in this posture which seems to suggest how the web can contract and expand. Also peculiar are the small epidermal photophores on the arms that seem to align in series. In the right image, the arms are aligned and the presence of a web is hardly noticed.
