Halicryptus Explained

Halicryptus is the sole genus of its class of priapulid worms, and grows to great size.^[1] It has an important effect on the structure of soft-sediment communities.^[2]

This genus contains the following species:

• Halicryptus higginsi
• Halicryptus spinulosus - type species

Maximum trunk length of Halicryptus spinulosus is 40mm, but usually belov 25mm. Halicryptus higginsi can reach 385mm.^[3]
