That orc had better be a good swimmer!
Although I still think CR 1/2 is far too low, I'll concede, as the bloobloater ooze in the Fiend Folio is only CR 1, and has 1 more Hit Die and blood drain.

Unlike the other dinoflagellates listed above, Noctiluca is not armored. It is incapable of photosynthesis, and survives by capturing other organisms with its tentacle and ingesting them. The tentacle will not damage an adventurer, unless it wraps around his throat (roll of 1 on d8), in which case it does 2-7 hp damage. Once ingested (which takes 3-5 rounds), a character suffers 1-3 hp damage per round until rescued or slam.
Noctiluca has a very potent flash, capable of blinding a character within 20’ for 5-15 rounds unless a saving throw vs. spells is made at -3. A blinded character will automatically drop any weapons in hand. A character making the saving throw will be startled for one round and must save vs. breath weapon (with dexterity bonuses) orldrop his weapons. At a range of 20-80’, a failure to save vs. spells (at -2) will produce a two-round startle response, with an additional throw against dropping weapons. Note that any characters which have been ingested will also be affected by any flashes made.
This cell is able to grasp a heavily armored character (AC 5 or better) with its tentacle on a roll of 13, lightly- armored characters (AC 6 to AC 8) on a roll of 14, and those without armor on a roll of 15. Shields place a -1 penalty on these attacks, but the cell attacks blinded characters at an additional +3 to hit, and startled characters at +2.
Noctiluca has only one very small flagellum, and moves by flailing its tentacle or grasping the bottom. It has a large eye spot and is able to detect changes in light and dark. It is only found in salt water, most commonly in the tropics.
