Chelonia mydas? Quite unsure about this one, as the identifiers I usually use for turtles are not visible in the silhouette photo (beak and number of claws).

Perhaps someone can see something else? Statistically this should be a green turtle, but cannot confirm it from the photo alone.

Arachnobas is a genus of weevils peculiar to the Moluccas and New Guinea.
When caught by an animal (e.g. me), immediately this beetle turned to lay on the back and moved its legs like a spider; probably mimicry.

This nymph of a bush-cricket, ~2-3cm, looks like a giant ant (mimicry);
however, ants (Hymenoptera) neither have such - long - antennae nor such strong hind-legs (femur)!
The colouration supports the mimicry: the dark colour of antennae is interrupted by a broad white part, hence they seem to be short like the ones of ants. The same happens with the colourful neon-stripes that legs seem thin and the body seems constricted... like a real ant!

We (my Indonesian student Sheherazade and I) have a Pteropus-durian pollinator/seed dispersal study going on out in Sulawesi right now and part of that study requires capture of other co-occurring fruit bats. She got this feisty female yesterday, on a very small island that does not have any fruiting trees, so we suspect that she roosts here.

We are calling this a Nyctimene cephalotes for now, but the yellowish eye rings are an interesting morphological trait. The species is recognized to have a rathe wide distribution, so taxonomic questions are not surprising given the lack of study into this group thus far.
