What is the difference between a Striped Marlin and a Blue Marlin

The Marlins are probably every sport fishing angler’s dream fish. Nothing can get better than standing on board your boat holding a beautiful creature such as the Marlin that gave you such a fight that your entire body feels battered. Sport fishermen all around the world go in search of these magnificently beautiful fish that are both strong and huge.

Of all the Marlins the Striped Marlin has always fascinated me. This beautiful fish is one of the rare beauties in the marine world. With vibrant stripes that can change color when excited for example when feeding. The otherwise blue stripes will change color to a luminous blue or a shiny lavender. These fish when they die also develop distinct stripes along the sides of their body.

Talking about Striped Marlin, I recently happened to read an edition of the Marlin Mag and came across this highly informative article on Marlins. Couldn’t be without sharing this piece of information with you guys. If you love fishing you should definitely know that the Marlin is considered to be one of the best game fishes owing to their spectacular speeds and aerial acrobatics.

Many anglers, even after multiple fishing expeditions can find it difficult to distinguish a Striped Marlin from a Blue. This is because Blue Marlins also have subdued stripes on their body that can confuse anglers most of the time. So when a Marlin pops up the surface of the water with its amazing agility and bright glistening blue body, how do you know if it a Stripey and not a small Blue Marlin?

According to the experts at Marlin Mag there are three very important aspects that can be considered to distinguish a Blue Marlin from a Striped Marlin and they are:

  • The Dorsal Fin

  • The Shape of the Body and

  • The Shape of the Lower Jaw

The prime distinguishing feature is the dorsal fin of these fish. If it is a Blue Marlin, the dorsal fin will not be taller than half the depth of the fish’s body. Whereas, if it is a Striped Marlin, the dorsal fin will be as tall as the entire depth of the fish’s body. So when the Marlin pops up check the length of the dorsal fin and if you notice a taller fin then that is definitely a pretty Stripey.

Next distinguishing feature is the body shape. A Blue Marlin will have a rather rounded body unlike the Striped Marlin which has a rather flattened body when compared to the Blue. As explained by the expert, if you cut both the Marlin into halves the cross section from the Blue Marlin will look more rounded than that of the Striped as the Striped Marlin will have a cross section that will look more similar to the shape of an egg ie, oval.

The final feature that clearly distinguishes both the Marlin species from each other is the shape of the jaw. The Blue Marlin has a short and broad lower jaw whereas the Striped Marlin’s lower jaw is narrower and pointed.

Now you know how to differentiate between these two Marlin species. So, next time a Marlin shows itself in the duration of your fishing trip you can be sure to spot the right one without confusion. And thus you can outshine your fellow anglers and be the knowledgeable one among the lot.

If you want to target Striped Marlins in your next fishing trip then the best place to be is Cabo San Lucas in Mexico. This place has been acknowledged as the hub of Striped Marlin activity in the world. Striped Marlins are found in Cabo San Lucas all year round however the period between February to August is considered the best season to go Stripey fishing.
