Identifying Sea Scorpions - Long Spined and Short Spined
« on: January 08, 2015, 03:41:26 PM »
When you catch a Sea Scorpion (also known as Bullhead) there are three main ways to determine if it is the Long Spined or Short Spined species...

1. The Spines
The name refers to the spines positioned either side of the head at the back (top) of the gill cover. In the Long Spined Sea Scorpion they are typically about half an inch long whereas in the Short Spined Sea Scorpion they are very short almost stumps. If you compare them to the size of the eye then those of the LS are much longer than the eye but those of the SS are smaller than the eye.

2. Size
The Short Spined Sea Scorpion can grow very large (30cm) whereas the Long Spined Sea Scorpion typically grows to around 18cm. If you catch a big one it will be a Short Spined Sea Scorpion.

3. The Gill Flap
Turn the fish over and tilt it's head back slightly. The gill flap on the Long Spined Sea Scorpion is attached to the throat in the middle but the gill flap of the Short Spined Sea Scorpion is not attached.
