Blunt Slipper Lobster- Facts and Photographs

Blunt Slipper Lobster (Scyllarides squammosus)

The Blunt Slipper Lobster (Scyllarides squammosus)  is an unusual looking clawless lobster.  They are usually only active at night and during the day they are almost never seen, being adept at hiding themselves. Being Crustaceans they undergo frequent molts of their carapace as juveniles and the adults molt once a year.

APPEARANCE

The body is collectively covered in a hard carapace made up of six segments on the head and eight on the thorax. The head has two pairs of antennae, one large and flattened pair covering the front of the sculptured slipper lobster and the other set are normal.

Blunt Slipper lobster are predominantly a light reddish brown color mixed with yellow in some areas. The first segment of the tail is a light yellow with three characteristic circular brown marks on it. The eyes are ringed with orange dots. Dependent on how long the period is since the shell change , there is often abundant algal and other growth on the shell. The body is flattened and the upper surface is covered with short hairs and tubercles.  The legs are a lighter orange-yellow colour and have purple on the joints.

REPRODUCTION

Blunt Slipper lobsters have separate sexes and at maturity which is generally around three years begin breeding. Males deposit a sperm packet on the underside of females and females have between 54000 to 240000 eggs which are carried under their tail. The eggs start off bright orange and as they develop so they go a dark muddy brown colour. Once the eggs hatch they become planktonic, free floating in the water table for up to six months. Very few of the larvae survive until adult stage. They obtain sexual maturity at approximately 6.6 to 7 cm in length.

COMMERCIAL EXPLOITATION

Slipper lobsters are eaten throughout their range and taste exactly the same as normal lobsters except they do not grow that large. They are trapped in fish traps in Tanzania and Zanzibar. This species which grows up to 40 cm is the largest Slipper Lobster on the East African coast.
