Calliphora bryani Kurahashi

Rawaki Blow Fly (Calliphora bryani)

The Rawaki Blow Fly is obviously endemic to the island of Rawaki, where it feeds upon the carcasses of dead seabirds.

It is an about 0,5 to 0,7 cm long fly with a reddish-brown thorax, which is silver-grey dusted throughout. The abdomen is glossy bronze in color, the legs are reddish brown. The wings are hyaline.

The Rawaki Blow Fly is viviparous, that means it doesn’t lay eggs but gives birth to fully developed larvae.

Coenobita perlatus H. Milne Edwards

Strawberry Hermit Land Crab (Coenobita perlatus)

This species is distributed throughout the whole tropical Indopacific region, from the coasts of Africa up to East Polynesia, where it can be found in large numbers especially on the atolls of the Tuamotu Archipelago.

The animals mostly stay close to the beaches, where they feed on all applicable things they can get, including seeds washed up to the beach or fallen coconuts, but also washed up fish and dead seabirds.

Strawberry Hermit Land Crabs prefer the shells of sea snails of the genus Turbo.

***

This species is endemic to the tropical Pacific where it breeds in parts of Melanesia (Vanuatu) well into eastern Polynesia, it is, however, mostly seen far away from its breeding grounds at sea where it searches for food.

The Polynesian Storm-Petrel is an about 25 cm large seabird, of which several color morphs are known to exist of which some were even considered to represent distinct species in former times, for example a remarkably dark morph that appears to be restricted to Samoa was formerly named as Samoan Storm-Petrel.

The species appears to prefer to breed on smaller, uninhabited islands where it is still quite rare, the breeding population on the island of Rawaki, Kiribati, for example, consits of only about 20 pairs. One of the largest known populations with about 100 birds breeds on the small and uninhabited Motu Motiro Hiva (Sala y Gómez). [1][3]

The kou is an about 7 to 15 m tall tree with a broad densely leaved crown.

This species occurs over a wide geographical range, as it can be found on the islands of the Indian Ocean up to almost all of the islands in the Pacific Ocean. In Polynesia this species can be found on all island groups, except for New Zealand and Easter Island.

The wood of the tree was (and still is) used for various carvings, and also for the production of canoes or paddles, as long as a large enough tree could be found.

On the Hawai’i Islands the tannin-containing leaves were used to dye bark cloth tan, but also to colour fishing lines, to make them less visible to the fishes. In Kiribati again the leaves were primarily used as pig fodder.

The bright orange flowers are often used for floral wreaths, and the seeds have been eaten in times of famine.
