Panulirus versicolor (Latrielle, 1804)
Spiny Lobsters (Panuluridae) lack the prominent claws and rostrum associated with true lobsters (Homarus spp.) Their carapaces have two frontal horns and are armed with numerous dorsal spines. The second antennae are thick, with spines on their first three basal segments, and are about equal to their body length. Panulirus versicolor has smooth abdominal somites, lacking a transverse groove. Abdominal somites 1-6 have a distinct, continuous transverse band along the posterior margins, with dark bands on either side of them. The third maxilliped lacks an exopod. The antennular plate, at the base of the 1st antennae, has 4 strong spines, in a square. The total body length reaches 400 mm, but the average maximum size is around 300 mm. Males tend to be larger than females. The carapace has a whitish background, with large areas of bluish-black. The peduncles of the antennae are pinkish, with thick black spines, and the flagellae of the antennae are white. (Description from: Holthuis 1991; Page 2013)
