Halimeda Kanaloana is a species of green algae (class Ulvophyceae) in the family Halimedaceae. This Species is indigenous to the Maui Nui island complex (Molokai, Maui, Lanai, Oahu, and Kahoolawe islands.)
Description
[edit]Halimeda kanaloana Vroom differs from related species through the combination of a large bulbous holdfast anchoring the specimen in sand, a basal thallus region of massive cylindrical to slightly flattened segments, large obovoid to cuneate trilobed segments in the central and distal thallus regions (median length 9-14 mm, width 6-11 mm, thickness 1.5-2.9 mm), medullar siphons fusing into a single unit at segment nodes, obvious pores connecting neighbouring siphons at segment nodes (median pore height including cell walls 47-69 µm), 4-5 utricle layers, large peripheral utricles (median diameter 56-73 µm, height 69-98 µm) that reach 42% of their maximal width at a quarter of their height and do not have rounded corners in surface view, and markedly inflated subperipheral utricles.
Distribution
[edit]The overall Geographic range of Halimeda Kanaloana is narrow, spanning in a few islands across Hawaii. It is endemic to the Maui Nui island complex or the islands of Molokai, Maui, Lanai, Oahu, and Kahoolawe.
Habitat
[edit]Halimeda kanaloana can be found in meadow 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. 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. Very rarely, specimens are found attached to rock.
