Tutufa bubo (Linnaeus, 1758)
210mm

Tutufa bubo is uncommon in the Marshalls. It is the largest of the Bursidae here; although the largest specimen we measured is 210mm, others observed in the field were clearly larger. The shell is usually thickly encrusted or eroded and the aperture of old adults can be somewhat expanded. We see these most often exposed on the seaward reef and lagoon pinnacles at depths of 3 to 25m.

The next is a very old animal with an eroded and pitted shell.

A young specimen has more black in its animal.

The next photo shows a very small juvenile less than 25mm in length.
