[MAK-roh-BRAY-kee-um ROH-zen-BUR-ghee-eye]

Syllable Breakdown

To make it easier, let’s look at each part of the name individually:

Macro-: MAK-roh (like "macro" in economics)
-brachium: BRAY-kee-um (the "ch" is a hard "k" sound, as in "anchor")
rosen-: ROH-zen (rhymes with "chosen")
-bergii: BUR-ghee-eye (the "g" is hard like in "goat," and the ending rhymes with "pie")

Note: You might occasionally hear people say BUR-jee-eye (with a soft "j" sound), but in botanical and zoological Latin, a hard "g" is generally preferred for names derived from German surnames like "Rosenberg."

2. Notes on macrobrachium rosenbergii

The first stage is called "small male" (SM); this smallest stage has short, nearly translucent claws. If conditions allow, small males grow and metamorphose into "orange claws" (OC), which have large orange claws on their second chelipeds, which may have a length of 0.8 to 1.4 times their body size.[6] OC males later may transform into the third and final stage, the "blue claw" (BC) males. These have blue claws, and their second chelipeds may become twice as long as their bodies.[4][6] Males of M. rosenbergii have a strict hierarchy; the territorial BC males dominate the OCs, which in turn dominate the SMs. The presence of BC males inhibits the growth of SMs and delays the metamorphosis of OCs into BCs; an OC keeps growing until it is larger than the largest BC male in its neighbourhood before transforming. All three male stages are sexually active, and females that have undergone their premating moult cooperate with any male to reproduce. BC males protect the females until their shells have hardened; OCs and SMs show no such behaviour.
