The burrow (lined with a calcareous coating produced by the clam’s mantle) is begun when the animal is in its larval stage and is expanded as it grows.
Shipworms are classified in the phylum Mollusca, class Pelecypoda or bivalvia, order Eulamellibranchia, family Teredinidae.

Christened by mariners, "termites of the sea," shipworms are parasitic mollusks that thrive in and upon submerged wooden structures, including pilings, bulkheads and the untreated hulls of boats.

Shipworm is designed to robustly enable IPv6 traffic through NAT, and the price of robustness is a reasonable amount of overhead, due to UDP encapsulation, transmission of bubbles, and relaying of packets through the Shipworm servers.
A "Shipworm" is a little saltwater critter that is common in the harbors of warm seas and that digs holes in immersed wood pieces, such as boat hulls or pilings.
Shipworm packets are always sent from either the Shipworm IPv4 anycast address, or from an IPv4 address and UDP port that is strictly consistent with the encapsulated IPv6 source address; this MUST be checked by servers and clients, as specified in sections 4.2.2 and 4.3.1.

The shipworm is a shellfish which, like the mussel, lives in a shell which opens up into two similar parts.
The shipworm lives in sea water and attaches itself to the wood of wooden-hulled boats and ships, where it causes damage by boring into the wood.
It apparently lives in the shipworm's special gland, and in contrast to the rumen bacteria of sheep and cows, which are of great variety, the gland of Deshayes seems to contain only the one kind of bacterium.

If a 3FFE-based prefix is temporarily requested, I would support allocating it for further testing, but don't think it matters at this stage given the test use of 2003 for this is already underway.
