The Johor Straits Singapore is one of the homes of the Carcinoscorpius rotundicauda species of horseshoe crabs that inhabit that part of the world.

Carcinoscorpius Rotundicauda are horseshoe crabs that can be found in the indo/west pacific waters and are getting dangerously close to extinction.

The part that makes me mad is that fishermen are using mono-filament nets on these shores and are leaving them unmanned.  The horseshoe crabs and other wildlife get caught in the nets and when the tide goes out are stranded on land where the heat quickly kills them.

The part that gives me hope is that this article tells how one person spent over 5 hours fighting time and the heat of the day cutting the nets away and releasing the horseshoe crabs so that they could get back into the water in order to survive.

I commend this individual and my only hope is that more people take an active role in helping wild life and that there be enacted laws to prevent fishermen from abandoning their nets and leaving the fish and animals entrapped in them to die because of their neglect.

Another species, Tachypleus tridentatus which are found in the Seto Inland Sea. (This one is considered endangered, although with regulation it seems to be making a come back.)

The third species is Tachypleus gigas is found off the coast of India.

The forth species is Carcinoscorpius rotundicauda and is also found off the coast of India.

There is one horsehsoe crab species that is extinct and that is Lunataspis aurora. This is also the oldest of the species at about 450 to 500 million years.
