This species of shrimp can be easily confused with Allogalathea elegans (crinoid squat lobster) due to its long chelipeds, the visible shape of its cephalothorax, its abdomen slightly curved under the body and by its colours. However, Allopontonia brockii differs in several points from Allogalathea elegans:
Allopontonia brockii is widespread through the Indo-Pacific, Red Sea included, and the eastern coast of the Pacific Ocean.[1]
Allopontonia brockii is considered as a commensal species from different species of sea urchins like some of the genus Salmaciella, Salmacis, Asthenosoma or Pseudoboletiana.[3] However, Allopontonia brockii can usually be observed on Asthenosoma varium (fire sea urchin).[2] Allopontonia brockii takes advantage of its host when it moves on the substratum to collect its food during the way and also takes benefit of the potential food which can hang onto the sea urchin.
