Halimeda kanaloana is a species of green algae (class Ulvophyceae) in the family Halimedaceae. This species is endemic to the Maui Nui island complex (Molokai, Maui, Lanai, Oahu, and Kahoolawe). [1]
Halimeda kanaloana is characterized by a large, bulbous holdfast that anchors the specimen in sand. The basal thallus region consists of massive cylindrical to slightly flattened segments. In the central and distal regions of the thallus, the segments are large, obovoid to cuneate, and trilobed, with a median length of 9-14 mm, a width of 6-11 mm, and a thickness of 1.5-2.9 mm [2] . The medullar siphons fuse into a single unit at the segment nodes, and pores are visible connecting neighboring siphons. The median pore height, including cell walls, is 47-69 µm. The plant has 4-5 layers of utricles, with large peripheral utricles measuring 56-73 µm in diameter and 69-98 µm in height. [2] These utricles reach 42% of their maximal width at a quarter of their height and have angular corners in surface view. [2] The subperipheral utricles are markedly inflated.
The overall geographic range of Halimeda kanaloana is narrow, spanning a few islands across Hawaii. It is endemic to the Maui Nui island complex or the islands of Molokai, Maui, Lanai, Oahu, and Kahoolawe. [3]
Halimeda kanaloana can be found in meadows in sandy environments. Occasional individuals are found as shallow as 1–2 m, with dense stands beginning at 15 m and ending abruptly around 85 m. [4] Specimens are anchored in sand by means of a gritty, bulbous anchoring holdfast, up to 8 cm in length, which the rhizoids cling tightly to sand. [3] Very rarely, specimens are found attached to rock.
Molokai is the fifth most populated of the eight major islands that make up the Hawaiian Islands archipelago in the middle of the Pacific Ocean. It is 38 by 10 miles at its greatest length and width with a usable land area of 260 sq mi (673.40 km2), making it the fifth-largest in size of the main Hawaiian Islands and the 27th largest island in the United States. It lies southeast of Oʻahu across the 25 mi (40 km) wide Kaʻiwi Channel and north of Lānaʻi, separated from it by the Kalohi Channel.

Hawaiian hibiscus are seven species of hibiscus native to Hawaii. The yellow hibiscus is Hawaii's state flower. Most commonly grown as ornamental plants in the Hawaiian Islands are the non-native Chinese hibiscus and its numerous hybrids, though the native Hibiscus arnottianus is occasionally planted.
Halimeda is a genus of green macroalgae. The algal body (thallus) is composed of calcified green segments. Calcium carbonate is deposited in its tissues, making it inedible to most herbivores. However one species, Halimeda tuna, was described as pleasant to eat with oil, vinegar, and salt.
Codium is a genus of edible green macroalgae under the order Bryopsidales. The genus name is derived from a Greek word that pertains to the soft texture of its thallus. One of the foremost experts on Codium taxonomy was Paul Claude Silva at the University of California, Berkeley. Silva was able to describe 36 species for the genus, and in honor of his work on Codium, the species C. silvae was named after the late professor.
Bryopsis, often referred to a hair algae, is a genus of marine green algae in the family Bryopsidaceae. Species in the genus are macroscopic, siphonous marine green algae that are made up of units of single tubular filaments. They can form dense tufts up to 40 cm in height. Each cell is made of up an erect thallus that is often branched into pinnules. Approximately 60 species have been identified in this genus since its initial discovery in 1809. The ecological success of Bryopsis has also been attributed to its associations with endophytic bacteria that reside in the cytoplasm of their cells.
Struvea is a genus of green macroalgae in the family Boodleaceae.
Udotea is a genus of green algae in the family Udoteaceae.
The genus Umbraulva, which is a green alga within the Ulvaceae family, was proposed by Bae and Lee in 2001. Three additional species, including U. kuaweuweu, which was subsequently transferred to another genus, have been added to the genus since it originally had the three species that were initially examined to form the genus. Umbraulva species grow upon hard substrates, and inhabit deep subtidal areas. Species within this genus are widely distributed, and have been identified in Asia, Europe, Hawaii, and New Zealand. The morphological traits of Umbraulva vary among species, but commonly, Umbraulva are macroscopic with olive green blades containing the photosynthetic pigment siphonaxanthin. The blades are flattened and ellipsoid in shape, or are narrow and oval shaped, with perforations and/or lobes present throughout the blade. As Umbraulva often appear very similar in morphology to closely related groups, the main manner in which Umbraulva was differentiated from related groups was through the divergence of ITS and partial SSU rDNA sequences from those of other Ulva species. Umbraulva is closely related to Ulva, which due to wide distributions, high carbohydrate levels, and a lack of lignin, is a good candidate for use in biofuel, bioremediation, carbon sequestration, and animal feed production.
Halimeda tuna is a species of calcareous green seaweed in the order Bryopsidales. It is found on reefs in the Atlantic Ocean, the Indo-Pacific region and the Mediterranean Sea. Halimeda tuna is the type species of the genus Halimeda and the type locality is the Mediterranean Sea. The specific name "tuna" comes from the Taíno language, meaning "cactus" and referring to the resemblance of the thallus to the growth form of an Opuntia cactus.
The East Molokai Volcano, sometimes also known as Wailau for the Wailau valley on its north side, is an extinct shield volcano comprising the eastern two-thirds of the island of Molokaʻi in the U.S. state of Hawaii.
Neraudia sericea is a rare species of flowering plant in the nettle family known by the common name woodland ma'oloa. It is endemic to Hawaii. It has been found on the islands of Molokai, Maui, Lanai, and Kahoolawe, but it has only been seen recently on Molokai and Maui. There are fewer than 200 individuals remaining. This is a federally listed endangered species of the United States.

Walter Ritte Jr. is a Native Hawaiian activist and educator from Ho‘olehua, Moloka‘i, Hawai‘i. He began his activism as one of the "Kaho‘olawe Nine," a group of activists who were the first to land on the island of Kaho‘olawe in January 1976 in opposition to the military bombing that was then taking place on the island. Other occupations took place and Ritte, along with Richard Sawyer, occupied and stayed hidden on the island for 35 days, an act which led to his arrest and brief imprisonment. The island was eventually returned to the State of Hawai‘i.
A mesophotic coral reef or mesophotic coral ecosystem (MCE), originally from the Latin word meso (meaning middle) and photic (meaning light), is characterized by the presence of both light-dependent coral and algae, and organisms that can be found in water with low light penetration. Mesophotic coral ecosystems occur at depths beyond those typically associated with coral reefs as the mesophotic ranges from brightly lit to some areas where light does not reach. Mesophotic coral ecosystem (MCEs) is a new, widely-adopted term used to refer to mesophotic coral reefs, as opposed to other similar terms like "deep coral reef communities" and "twilight zone", since those terms sometimes are confused due to their unclear, interchangeable nature. Many species of fish and corals are endemic to the MCEs making these ecosystems a crucial component in maintaining global diversity. Recently, there has been increased focus on the MCEs as these reefs are a crucial part of the coral reef systems serving as a potential refuge area for shallow coral reef taxa such as coral and sponges. Advances in recent technologies such as remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUVs) have enabled humans to conduct further research on these ecosystems and monitor these marine environments.

Hurricane Olivia was a tropical cyclone that impacted Hawaii as a weakening tropical storm in mid-September 2018, causing severe flooding and wind damage. Olivia was the first tropical cyclone to make landfall on Maui and Lanai in recorded history. It was the fifteenth named storm, ninth hurricane, and sixth major hurricane of the 2018 Pacific hurricane season.
An earthquake struck near the Hawaiian island of Lanai on February 19, at 10:11 pm HST with an estimated magnitude of 7.5 on the moment magnitude scale (Mw ). It remains one of the largest seismic event to hit the Hawaiian Islands since the 1868 Kaʻū earthquake, with its effects being felt throughout the entire archipelago. It caused severe damage on the islands of Lanai, Molokai and Maui. A tsunami may have been generated however there are speculations if it had actually happened. Despite the size of the quake and the extent of damage, there were no deaths.
