Project Description

These giant sea spider eggs (Nymphon pixellae) are carried on specialized legs (ovigers) by the male.  After a brief courtship, eggs are fertilized as they leave the female, and it’s only the male sea spider that carries and protects the eggs until they hatch.  The pincer-like mouthparts (chelifores – refer to sketch below) are used to bring food items towards the mouth.  The palps are used for touch, holding food items, or helping with guiding the sea spider’s large snout (proboscis).  Giant sea spiders can grow to 1.5 inches (3.5 cm) across, with a range from British Columbia to Mexico.
