A fruit plate was apparently requisite for any reputable snorkeling tour . We swam out in the direction that Carlos had suggested . We did n't really see new coral that we had n't seen before , but it was a good area , spectacular with coral growth . The types we saw : brain , lettuce leaf , fan , mustard hill and a few others that we did n't learn the names of , like one with purple fingers .
What may be a fact about the two people in this situation ?
