Whale shark!

It's a tricky one.

Not that I care too much about it but let's "ask the experts":

What are the plurals of 'octopus', 'hippopotamus', 'syllabus'?

English words of Latin or Greek origin have rather unpredictable plurals, and each one usually depends on how well established that particular word is. It may also depend on whether the Latin or Greek form of the plural is either easily recognizable or pleasant to the speaker of English.

Although it is often supposed that octopi is the 'correct' plural of octopus, and it has been in use for longer than the usual Anglicized plural octopuses, it in fact originates as an error. Octopus is not a simple Latin word of the second declension, but a Latinized form of the Greek word oktopous, and its 'correct' plural would logically be octopodes.

Other words ending in -us show a very varied pattern. Like octopi, the plural hippopotami is now generally taken to be either funny or absurdly pedantic, and the usual plural is hippopotamuses. Common usage appears to indicate a slight preference for termini rather than terminuses, but syllabuses rather than syllabi. Other usual forms include cacti and gladioli, and our files at the dictionary department show scarcely any examples of nucleuses or funguses. (Omnibi is simply a joke, and quite ungrammatical in Latin!)

Among words ending in -um it seems worth drawing attention to the word curricula, plural of curriculum, and warning against confusion with the adjective curricular (as in extra-curricular).

By the way, how does one get to the Black Rock nowadays? I must say, being relatively new to the area, this was the first time I've heard of it.

The only way to get to Black Rock is on a Liveaboard boat that includes the Mergui Archipelago in Myanmar in its itinerary. Not all boats venturing in Burmese waters will go to Black Rock though because it's quite a bit up North in the Mergui waters.
If you book a Liveaboard make sure to check where they will dive.
I find Black Rock either excellent or average with nothing inbetween. The best months to dive it are March and April with chances on bigger animals and tons of smaller creatures.

And ofcourse octopi, oops OCTOPUSES. Lots of those out there in the daytime frolicking inbetween the rocks and soft corals.

Does not matter how you spell their names - it's great when you can get close.

Here's an ex-diver friend of mine checking one out
