再到片段. 斑紋呈褐色, 不是呈橙色, 會是橙紅陸寄居蟹(Coenobita perlatus)的幼體?

另外, 全身並不是橙紅,只有橙色斑紋的幼體.

長大後會不會長成這個樣子?

Found another movie from instagram, the small crab with dark brown transverse band on the walking leg, is this crab juvenile of Coenobita perlatus?

On the other hand, if the small crab, whole body colour is not in orange red, only transverse band is orange.

When they grow larger, will look like this?

品種研究 / Coenobita new species (中文):
http://www.tonycoenobita.com/species_ch.htm

找到以下照片, 這幼體不太像棲身於關島的品種, 如灰白陸寄居蟹(Coenobita rugosus), 橙紅陸寄居蟹(Coenobita perlatus), 短腕陸寄居蟹(Coenobita brevimanus).

這會不會很有機會是棘足陸寄居蟹(Coenobita spinosus)的幼體? 隨著身體長大, 體色會漸漸變成紅豆至褐色?

因為看不到左螯......或許只是灰白陸寄居蟹(Coenobita rugosus)的幼體, 現在對棘足陸寄居蟹(Coenobita spinosus)這品種的資料實在太少.

Image from below instagram, this young crab do not like other speices that can found in Guam, such as Coenobita rugosus, Coenobita perlatus and also Coenobita brevimanus.

So is it possible this one is juvenile of Coenobita spinosus, when they group up, they will become dark red to brown?

As cannot see clearly the big claw, may be this one is juvenile of Coenobita rugosus, there are still little information about Coenobita spinosus.
