Pantopoda, or Sea Spiders, are a remarkable group of Arthropod animals, perhaps intermediate between Crustaceans and Arachnids. They are spider-like organisms, having four well-developed walking legs, often of great length. The body consists of an unsegmented proboscis, a trunk of four segments, and an unsegmented abdomen. There are no gills -- a point of distinction from the crustaceans; but the number of appendages in front of the legs is different from that of the true spiders. In the more typical forms there are three appendages in front of the legs -- first a small pair of chelate limbs, then two pairs of slender appendages. The first of these are used like the chelae in food getting; and the second seem to be functionless in the female, while in the male they carry the eggs. In the common shore sea spider <i> (Pycnogonum littorale) </i> , however, the two anterior appendages are absent in both sexes, and the third or egg-carrying pair are present only in the male. This form is found beneath stones, and is of a yellowish color, with thick, knobbed legs. Another common form is <i> Phoxichilidium femoratum </i> , which is of a pink color, has very long legs, and is commonly found on bright-colored weeds in shore pools. A representative American species is <i> Phoxichilidium maxillare </i> , which spreads about an inch and varies in color from deep brown to almost white. It is commonly found in shore pools; and its young live for a time withing hydroids. It is in the ocean abysses that the sea spiders reach their maximum size. One deep-sea form <i> (Colossendeis gigas) </i> has a span of nearly two feet from tip to tip of the legs. There is a metamorphosis in development in the sea spiders, the larvae having at first three pairs of appendages.
