I have been found as far south as Su-ao, in Eastern Taiwan.

the Japanese giant spider crab is the largest known living arthropod.

Adults can reach nearly 4 meters long from one tip of one cheliped (a claw-bearing leg) to the other when stretched apart.

Females tend to have wider, although slightly smaller, abdomens than males.

I tend to be orange with a bunch of white spots allover my body.

Once I'm an adult I my body tends to stay the same size but my legs lengthen as I get older.

• only around 75% survive the first zoeal stage.

• This number drops to around 33% for the second zoeal and megalopa stages.
