Cephalopod Freak Show

Unfortunately, Zoologix beat us to the story of Henry the Hexapus. Henry, caught in a lobster pot off north Whales, is the first reported six-legged octopus. The loss of two limbs did not occur from a tangle with some thug octopus but rather results from a birth defect. If you're interested in how such a thing could happen in this beautiful world, PZ has a whole post on HOX genes and cephalopod development that is good preliminary reading. How common are octopod defects? Below the fold is something we like to call Cephalopod Freak Show!
  1. Heptapus: Gledall (1989) "A male specimen of Octopus is described which has only seven arms"
  2. Double Tentacle Bifurcation in Moroteuthis ingens reported by Gonzalez and Guerra in JMBA.

This six-legged octopus- the first ever known to science -was hauled in from a catch off of the coast of Wales. His lack of two limbs appear to be the result of a birth defect not an insurgent IED. The hexapus has been named "Henry" and now resides at the Blackpool Sea Life Centre in Northwest…
Researchers have been very concerned about the paucity of females of Vulcanoctopus hydrothermalis, an octopus inhabiting the hydrothermal vent community of the Eastern Pacific Rise. One senior, conservative squid researcher even went so far as to comment that this octopus was some part of a "queer…
Vulcanoctopus hydrothermalis (Mollusca: Cephalopoda: Octipodidae) Octopus are one the most fascinating and intelligent of the invertebrates. Yet, little is known about their role in the deep sea, even less is known from methane seeps of hydrothermal vents! In fact, only one species has been…

Thanks, Craig. While I always find your cephalopod posts entertaining, I'm afraid that your new upstart has raised, er, lowered the bar considerably with his last posting on the reproductive lives of bone-eating worms. Now, if we just played around with your "double tentacle bifurcation"... on second thought, scratch that idea!
