Macrophthalmus convexus Stimpson

Convex Sentinel Crab (Macrophthalmus convexus)

The Convex Sentinel Crabs are very small crabs having an average carapace diameter of about 1 x 1,5 cm to 1,5 x 3 cm and exceedingly long eyestalks.

They live in the intertidal zone, where they can be found abundantly on muddy places near the outlets of small streams, and are therefore absent from islands without such freshwater streams, e.g. the Tuamotus. The crabs feed on smallest food particles, which they sift out from the sand.

These crabs dig their burrows in muddy sand, in which they flee at the slightest disturbance.

On Aitutaki the crabs are called papaka.

Pteropus tonganus Quoy & Gaimard

Tongan Fruit-Bat (Pteropus tonganus)

The Tongan Fruit-Bat occurs with several subspecies in an area that stretches from New Guinea to the Cook Islands in Central Polynesia, whereby the form, that can be found in Polynesia, represents the nominate race.

These animals reach a wing span of more than one metre and spend the day more or less sleeping in roosting trees, where they sometimes form giant colonies.

In most parts of its geographic range the species is an important source of protein and is therefore heavily hunted, but also because the Fruit-Bats, being frugivores, can cause enormous damages in fruiting trees. Hence the species has become rare in some parts of its geographic range, in others it has even disappeared completely.

In the Kingdom of Tonga in contrast Tongan Fruit-Bats are considered as property of the royal family and therefore are protected from hunting – a very effective protection.

On the Cook Islands, the eastern most edge of its distribution area, the Tongan Fruit-Bat is called moa kirikiri, which means ‘leather chicken’. On the Fijian Islands it is called beka, bekua (in the west part of Viti Levu), beka dina or doli (on Kadavu).

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.

Euploea lewinii Felder & Felder

Crow Butterfly (Euploea lewinii)

This species, whose taxonomy is very confusing, occurs with several (?) subspecies within the Polynesian region, whereby, however, it seems not to be completely known, how far they are distributed here naturally.

Shown here is the Fijian subspecies (Euploea lewinii ssp. eschscholzii Felder & Felder).

Additional subspecies occur on the Samoan Islands (Euploea lewinii ssp. bourkei (Poulton)), on Tonga (Euploea lewinii ssp. mathewi (Poulton)) as well as on Niue and the Cook Islands (Euploea lewinii ssp. perryi (Butler)).

The caterpillars feed on the leaves of various fig species, including the Pacific Banyan (Ficus prolixa G. Forst.) and the Dye Fig (Ficus tinctoria G. Forst.).

The Horn-eyed Ghost-Crab is indigenous to the Indo-Pacific, where it occurs from the coasts of East Africa far into Polynesia, where the animals run about the beaches in search for edible things, including washed up dead fish, or dead sea birds, but also newly hatched sea turtles.

It is a quite large species with a carapace size of up to 8 cm in diameter. It can be distinguished from other related crabs by the eyestalks extending beyond the eyes into long points, those stalks are longer in males, and shorter or almost absent in females.

In Samoa, the species is called avi’ivi’i resp. pa’a.

The Screw Pine is a geographically widespread and exceptionally morphologically variable species (or maybe a species complex). In the Polynesian region this plant is found almost everywhere, except for climatically inappropriate areas like New Zealand or Rapa Nui.

The Screw Pine was once one of the most important plants for the Polynesians, and Screw Pine saplings, together with saplings of Breadfruit Trees, Coconut Palms, Taro and several others, were transported by the Polynesian settlers on their boats during inter-island migration – to be planted out at their new island homes.

The Polynesians, over time, reared numerous cultivars, among them such whose leaves are lacking spines on their margins, and which therefore are very well-suited for weaving.

The exceptional variability of the wild and cultivated forms lead to the description of countless species, subspecies and varieties. So, Harold St. John alone described in his “Revision of the Genus Pandanus” various female plants as distinct species – in many cases from geographically very localized populations. In a biological sense, all of these ‘species’ are part of the same population, and furthermore, it is impossible to designate male plants to such ‘species’.

Some of the morphologically distinct forms that are seemingly restricted to the higher elevations of larger islands, like Pandanus papenooensis H. St. John on Tahiti or Pandanus temehaniensis J. W. Moore on Ra’iatea, are often still referred to as distinct species.

(I personally, however, see all of these forms as Pandanus tectorius.)

Nevertheless, the genus is in urgent need of a proper revision!

~~~

As already mentioned, in virtually all parts of Polynesia the leaves were and are used for weaving, among other things, for elaborate mats, especially in Tonga, or boat sails (in former times on the Hawai’i Islands), right up to roofs and walls of houses (!). The stilt roots were used, for example, on the Cook Islands, for house building (as abutment walls) too.

The fruits are fruit heads comprising an aggregate of many tightly bunched phalanges or drupes that are edible. In some cultivars, these drupes reach the size of an apple. They are eaten especially in parts of Kiribati, Tokelau, and in Tuvalu.

Egretta sacra (Gmelin)

Pacific Reef-Egret (Egretta sacra ssp. sacra)

The Pacific Reef-Egret is an about 60 cm large, rather short-legged egret, that lives predominantly in coastal areas.

The birds occur in mangrove-filled estuaries or along rocky shores, where they feed on small fish, mollusks and crustaceans.

The nominate race of this species occurs from South and Southeast Asia to Australia and into almost the whole pacific region (with the exception of New Caledonia, the Solomon Islands and Vanuatu, where the ssp. albolineata (G. R. Gray) occurs).

In some regions of Polynesia the Pacific Reef-Egret is nowadays the only surviving of the native bird species.

There are three color morphs, dark slate grey colored birds, pure white birds as well as an intermediate phase that is mottled white with dark slate grey. It is a somewhat strange fact, that in some areas, for example New Zealand and Samoa, only birds of one of these morphs (in both cases the dark morph) are breeding, while in other places all three morphs live together.

Ischnura aurora Brauer

Aurora Bluetail (Ischnura aurora)

The genus Ischnura is distributed nearly worldwide, within the Polynesian region it contains 13 described species, plus at least an additional ten hitherto undescribed species, which are known to await their description alone on the Society Islands.

~~~

The Aurora Bluetail is a wandering species, which occurs from India well into East Polynesia.

It is a smaller damselfly species, which reaches a wingspan of about 3 cm. The males are very colorful (see photograph), while the females are rather plain light brown in color.

~~~

The enigmatic Spinytail Forktail (Ischnura spinicauda (Brauer)), described in the year 1865 as a distinct species, is now known to be identical with the Aurora Bluetail. [7]

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.
