Comprehensive Description

Read full entry
This animal is NOT a crustacean. As a chelicerate, it has chelicerae instead of jaws. This species has legs which are longer than the combined length of the proboscis and trunk. The general outline of the animal is circular. It has both chelicerae and pedipalps. Both sexes have an ovigerous pair of legs (photo) (though as in pycnogonids in general, it is the male which carries the eggs). The chelicerae are reduced to a knob or tubercle, and are small and hard to see. The pedipalps have 6 or fewer articles. The body is not covered with setae. The proboscis is about twice as long as its diameter at the base, and is rounded at the tip (does not taper to a conical point). The lateral projections from the trunk are not large (in many other species there are obvious lateral swellings of the trunk at the base of each pair of legs).
