Choristodon robustus
- boring Chama macerophylla 1

This species is a boring species, which is known to bore into shell, rock and coral. Here it was found boring into Chama macerophylla, the Leafy jewelbox. It is included here as other American boring species have been found in the UK, although this species has not yet been recorded.

The piddock genus Martesia is known to bore into styrene fishing floats, so we cannot be certain if the species here will also bore into flotsam that is temporarily trapped on the seabed, before continuing it's journey to Europe via the Gulf Stream.

The Chama macerophylla containing Choristodon robustus was found by a diver in 80-90 feet of water, it was on a rock pile just off the Blackthorn Wreck, Pinellas County Artificial Reef #2, West of the mouth of Tampa Bay, Florida, USA, in 1988.

The species can be found in the Gulf of Mexico, the Caribbean, Costa Rica, Mozambique and Tanzania.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help

people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
