Hawaiian Swimming Crab — Goniosupradens hawaiensis — Pāpaʻi Holoholo

A Hawaiian swimming crab found at the Carpenter’s House dive site in Kona. This species is found on reef flats, rubble, and sandy areas throughout Hawaiʻi. Pāpaʻi Holoholo belongs to the swimming crab family and uses flattened rear legs as paddles to move through the water. It feeds on small invertebrates, carrion, and other food it finds while searching the reef.

Fun fact:
When disturbed, Hawaiian swimming crabs can quickly bury themselves in the sand, often disappearing completely in just a few seconds.

Pāpaʻi is the Hawaiian word for crab, and holoholo means to travel or move about, an appropriate name for one of Hawaiʻi’s swimming crabs.

Gloomy Nudibranch — Tambja morosa — No Known Hawaiian Name

A gloomy nudibranch found at the Turtle Heaven dive site in Kona. Tambja morosa is a member of the polycerid nudibranch group and is recognized by its dark body and contrasting markings. Like many nudibranchs, it feeds on specific prey, including bryozoans and other colonial organisms found on the reef. The rhinophores on its head detect chemical cues in the water, helping it locate food and potential mates.

Fun fact:
Nudibranchs are highly selective feeders. Many species eat only one or a few types of prey, which is why finding a particular nudibranch often means its preferred food source is nearby.

Shortnose Wrasse - Macropharyngodon geoffroy

A shortnose wrasse found at the Carpenter’s House dive site in Kona. This species is endemic to Hawaiʻi and is commonly seen foraging over reef rubble and coral heads for small crustaceans and other invertebrates. Juveniles and adults can look quite different, and the species is known for burying itself in the sand when resting or avoiding predators.

Fun fact:
Shortnose wrasses disappear into the sand at night, where they remain hidden until morning. This behavior helps protect them from nighttime predators.

White‑margin Nudibranch

Common name: White‑margin Nudibranch
Scientific name: Glossodoris rufomarginata
Hawaiian name: No documented name

Video of a White‑margin Nudibranch at the Carpenters House dive site in Kona. This species lives on coral and rocky reef surfaces and feeds on specific sponges. Individuals move slowly using a muscular foot and show mantle movements that help them sense water flow. The species occurs across the Indo‑Pacific, including Hawaiʻi.

🧠 Fun fact: Many Glossodoris nudibranchs release distasteful chemicals from mantle glands when disturbed, a defense gained from the sponges they eat.

Gosline’s Fangblenny

Common name: Gosline’s Fangblenny
Scientific name: Plagiotremus goslinei
Hawaiian name: No documented name

Video of a Gosline’s Fangblenny at the Carpenters House dive site in Kona. This individual was holed up in an abandoned worm hole in the wall of an underwater canyon. Fangblennies use crevices and holes as shelter and feeding stations. They feed on small invertebrates and are part of a group known for enlarged canine teeth and quick darting movements.

🧠 **Fun fact:** Some fangblennies produce venom that reduces pain in predators, helping them escape. *Plagiotremus goslinei* is not one of the venomous species but shares similar defensive behaviors.

Photo • Freckled Wire Coral Shrimp — Pontonides sp. 2 — No Known Hawaiian Name

A freckled wire coral shrimp found at the Golden Arches dive site in Kona. This shrimp lives in close association with wire corals, where its body pattern helps it blend into the branches of its host. Like other members of the genus Pontonides, it spends much of its life on a single coral colony, feeding on suspended particles and material collected from the coral surface.

Fun fact:
Freckled wire coral shrimp are often easier to find by locating the wire coral first. Even when in plain sight, their camouflage can make them difficult to spot.

Photo • Whitemouth Moray — Gymnothorax meleagris — Puhi

A whitemouth moray found at the Golden Arches dive site in Kona. This species is recognized by its dark body covered in small white spots and the pale interior of its mouth that gives it its common name. Puhi spend much of the day sheltering in holes and crevices, emerging to hunt fish, crustaceans, and cephalopods. Their open-mouth posture is normal and helps move water across the gills for breathing.

Fun fact:
Moray eels have a second set of jaws in their throat, called pharyngeal jaws, which help pull prey deeper into the mouth after a bite.

Photo • Locust Nudibranch — Hypselodoris peasei — No Known Hawaiian Name

A locust nudibranch found at the Golden Arches dive site in Kona. Hypselodoris peasei is a dorid nudibranch found in Hawaiʻi and other parts of the Indo-Pacific. Like many nudibranchs, it feeds on sponges and incorporates chemical compounds from its diet as a defense against predators. The feathery structure at the rear of the body is a gill plume, while the pair of rhinophores on the head are used to detect chemical cues in the water.

Fun fact:
Unlike sea slugs with a protective shell, nudibranchs rely on chemical defenses, camouflage, and warning coloration for protection.

Photo • Hawaiian Swimming Crab — Goniosupradens hawaiensis — Pāpaʻi Holoholo

A Hawaiian swimming crab found at the Turtle Pinnacle dive site in Kona. This species belongs to the swimming crab family, with flattened rear legs adapted for moving through the water. Pāpaʻi Holoholo is found on reef edges, sand, and rubble habitats, where it feeds on small invertebrates and scavenges for food. The species was formerly classified as Charybdis hawaiensis, a name still commonly encountered in older field guides and websites.

Fun fact:
Unlike most crabs, swimming crabs can use their paddle-shaped rear legs to swim and can quickly bury themselves in sand, leaving only their eyes exposed.

Pāpaʻi is the Hawaiian word for crab, and holoholo means to travel or move about—a fitting name for one of Hawaiʻi's swimming crabs.

Photo • Wire Coral Goby — Bryaninops yongei — No Known Hawaiian Name

A wire coral goby found at the Turtle Pinnacle dive site in Kona. This small goby lives in close association with wire and whip corals, where it spends much of its time perched among the branches. Bryaninops yongei is found throughout the Indo-Pacific, including Hawaiʻi, and feeds primarily on zooplankton carried by the current. It is often seen alone or in pairs on a single coral host.

Fun fact:
Wire coral gobies can change s*x during their lifetime. They are usually found in pairs and may switch s*x to maintain a breeding pair on their host coral.
