• Pycnogonum stearnsi

  Stearns' sea spider

  Pycnogonum stearnsi is a sea spider in the family Pycnogonidae, found on the Pacific coast of North America and in Japan. It reaches about 2.5 cm in length and lacks eyes, chelicerae, and pedipalps—unusual traits among sea spiders. It feeds by inserting its barrel-shaped proboscis into soft-bodied prey and sucking fluids. Males carry egg masses on specialized ovigerous legs.
