And I don't think holothurians are as quick to spill their guts as the
guide books suggest.

Locally, H. mexicana, I. badionatus, and H. thomasi are abundant.
Occasionally I run into the beautiful A. multifidus (a bright yellow one
last week) or a A. agassizii. All react to handling by contracting, but
I have never been able to frighten one enough to get it to
self-eviscerate. Not that I have tried very hard, but picking them up,
inverting them, poking at them, whatever, would seem to me to be
sufficient to trigger anti-predator responses.
