Traditional Classification vs Phylogenetic (using Fish as an Example)

Traditional classification

Traditional spindle diagram of the evolution of the vertebrates at CLASS level

Conventional classification has living vertebrates grouped into seven CLASSES based on traditional interpretations of gross anatomical and physiological traits. This classification is the one most commonly encountered in school textbooks, overviews, non-specialist, and popular works. The extant vertebrates are:

  • Subphylum Vertebrata: 7 Classes (often taught as 5 Vertebrate Classes, by collapsing the 3 fish classes into one)

In addition to these, there are two classes of extinct armoured fishes, the Placodermi and the Acanthodii, both of which are considered paraphyletic.

Natural history of brown stingray, part two —males do not have tails!?

Round stingrays are sexually mature at about 10 inches. During June the females move inshore from deeper water to mate with the males. After mating they return to depth, but are found back in the protected shallows in August and September when they spawn. Males are generally found in shallower water much of the year except winter when storms appear. The four inch young are born in litters averaging three but may have as many as eight according to Dr. Milton Love of the Love Lab at UCSB. They remain in very shallow water, less than 12 feet, until they reach 6-7 inches, then move into deeper water along more exposed coastlines. It is unlikely that bathers will encounter these rays in our waters during winter…

New Paper: Sevengill Sharks Replacing Great Whites as Apex Predator in Cape Town Area ~ Ocean Sanctuaries’ Sevengill Shark Sightings

The waters surrounding Seal Island in False Bay, South Africa, are known for great white sharks breaching out the water in pursuit of seals (left image), but the recent disappearance of great whites from here has led to the emergence of another apex predator, sevengill sharks that now dominate the area.

Fact? sharks are least attracted to the color red


www.spearboard.com/showthread.php

We would definitely think this is a false statement BUT couldnt be farther from the truth.

Sharks are LEAST attracted to the color Red. Fact. Tested colors: Red, Silver, Black, Yellow, White

They are attracted most by the color Yellow, then Black, Silver a very close third.

So you boys with your traditional black suits I feel for ya.


How this applies to (spearfishing for game fish while wearing…) Camo suits: (impo) The point is to pose as a ‘UMO’ if you will, ‘Unidentified Moving Object’ to the fish. Studies done on the Galapagos Islands with certain species that have never seen man before do not show an inherit fear of us because we are a ‘UMO’ to them. It is inherited in their brain/genes to have a ‘knee jerk’ reaction to predator looking objects. So if we de-preditorize ourselves and place ourselves on the side of ‘UMO’ then the chances are decreased in knee jerk reactions and raised in the curiosity levels. This is not a set rule but merely an odds game. Increase your odds in areas and decrease in others to have greatest result.

Yes Bill is right, wearing his all black or all grey color suit still many game fish have come in very close to hang out and chat, but this isnt to say curiosity over ruled there inherit flee response. We’ve all touched a hot stove top at some point in our lifes…

p.s. Hey Bill Mac, if you believe with the majority in quantum physics, be annoyed. Because in a parallel universe YOU bought a camo suit and YOU are landing HUUGE WSB at YT right now!
