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.

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.
