Fish that live head-up in a vertical burrow they dig and line themselves, and drop back into it tail first when anything comes close. The burrow is as much a part of the animal as the fins.
The burrow is built rather than found. The fish carries shell and coral rubble to the rim one piece at a time in its mouth, packs the walls, and rebuilds constantly, so a few minutes spent watching one hole shows the whole business of running a household. A jawfish will also carry a stone that is too big for it and give up.
Males brood the eggs in the mouth and do not feed while they are doing it. Every so often the ball is spat out and taken straight back in, which airs it and takes about a second. It happens more often early in the morning, and it is the photograph everybody in this group is after.
Approach decides everything. A jawfish that has gone down while you were moving will stay down. Settle on the bottom several metres back, wait for it to come back up, and close the distance over minutes rather than seconds.
Every one has a page. They are shown as a list rather than as pictures because nothing has been photographed or logged for them yet, and a species with nothing behind it should not sit in front of one that has.
How many of the 4 carry a record at each destination. A species usually carries several, so these do not add up to 4.
