Protobothrops flavoviridis, also known commonly as the Okinawa habu is a species of pit viper, a venomous snake in the subfamily Crotalinae of the family Viperidae. The species is endemic to the Ryukyu Islands of Japan. No subspecies are recognized as being valid. Local common names include habu and Kume Shima habu. The term "habu" in Okinawa Prefecture can also refer to the Sakishima habu (Protobothrops elegans) alternately called the elegant pit viper.
Growing to an average total length (tail included) of 4–5 feet (120–150 cm), with a maximum of 7.9 feet (240 cm), Protobothrops flavoviridis is the largest member of its genus. It is slenderly built and gracefully proportioned with a large head. The crown of the head is covered with small scales. P. flavoviridis has a light olive or brown ground color, overlaid with elongated dark green or brownish blotches. The blotches have yellow edges, sometimes contain yellow spots, and frequently fuse to produce wavy stripes. The belly is whitish with dark coloring along the edges.
The Okinawa habu is restricted to the Japanese Ryukyu Islands, including Okinawa and the Amami Islands... Wikipedia →

No species of the same family or order lives in Naha, so these are its closest relatives here: other reptiles.
Possible
About 20% of wildlife watchers report a Habu sighting in Naha on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 6th most-seen of the 6 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Habu in Naha on a given day, against under 5% in June, August and October–March, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Habu sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Naha, in our data
Naha is the only city on Wallace's Line with enough records to rate Habu sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Habu is recorded against all the reptiles logged in Naha (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
