Ancylomenes venustus
Translucent reef shrimp on host anemones, most reliably found across the Visayas and Luzon at 8-15m in warm Philippine waters.
Small, glassy-bodied shrimp with a see-through look broken up by fine purple or violet speckling along the body and legs, so it almost disappears against its host anemone until it moves. Long, thin walking legs and antennae give it a delicate, spindly silhouette rather than a bulky one. Look for it perched right on the anemone's tentacles, swaying gently, rather than tucked at the base.
Found clinging to and shuffling across the tentacles of its host anemone, usually holding station rather than swimming off when a diver approaches. It tends to sit at a slight remove from the anemone's centre, using its thin legs to grip while facing outward, and is easiest to spot once your eye has locked onto the host itself. Most logged encounters describe it as an uncommon find, so it rewards a slow, close look at anemones rather than a quick reef scan.
Like other anemone shrimp, it lives in a partnership with its stinging host, moving over the tentacles unharmed while gaining a defended perch that most reef predators avoid.
Sightings show no detectable seasonal pattern, and with water temperatures logged between 25.5 and 31.5 C it is effectively a year-round find on these reefs. Any month works, so plan around the destination rather than a calendar window.
Reef neighbours a diver could mistake it for. Use the identification notes above to tell them apart.
This one is essentially a Philippines speciality in the logged data, with sightings concentrated across the Visayas and Luzon regions. Divers looking for it should focus reef dives in these areas rather than treating it as a wide Indo-Pacific certainty, since that is where the confirmed record sits.
Mapping where Graceful Anemone Shrimp is logged…
The strongest logged sightings come from the Philippines, particularly the Visayas and Luzon regions. It is worth checking anemones closely on reef dives in these areas rather than expecting it on every host anemone you pass.
There is no clear seasonal pattern in the sightings, and the warm 25.5 to 31.5 C water it favours holds steady year-round on these reefs, so any month is a fair shot.
Look for a small, near-transparent shrimp with fine purple speckling, perched on an anemone's tentacles with long thin legs and antennae. The glassy body makes it blend into the host until it shifts position.
No. They are tiny, harmless shrimp with no sting or bite risk to divers, and they rely on their host anemone for defence rather than any weapon of their own.
It survives by living directly on a stinging anemone's tentacles, a partnership that protects it from predators while it moves freely over a host most other animals cannot touch.
