Rare Australian fish has fins like hands

The similarities between the handfish’s hand-like fins, crocodile feet, platypus forepaws and human hands does not mean that these have a common evolutionary ancestry. Rather, living things share many similarities because they share the same Designer. See www.creation.com/lookalikes.

The red handfish (pictured below) is one of several species of handfish that live in coastal waters of southeastern Australia. It has quite unusual fins. The front pair of fins look a bit like hands, while the pectoral fins are extended away from the body like arms, ending with a hand-like paddle. The fish pushes against the seabed with these fins to move along in search of food. It is quite capable of swimming quickly if the need arises, but it prefers to stay on the seabed most of the time.

The fish’s motion could be described as ‘walking’, but it is not the same kind of walk as that of land animals. Land animals support most or all of their weight on their legs, which must be strong and heavy-boned to work. But living under water, the handfish’s body weight is mostly carried by its buoyancy, so the fins bear little weight. Their structure is light, well-suited to its way of moving under water.

At least five species of handfish live around Tasmania. The red handfish (Brachionichthys politus) was first described in 1849, being found in the vicinity of the Port Arthur convict settlement. It is small, typically being about 8 cm (3.2 inches) long when fully grown. They live in depths of 2–30 m (6–100 ft). They were once fairly common in that area, but are now rare. Just a few specimens have been collected. Their habitat is quite restricted, as they are only found in a few places along Tasmania’s southeastern coast. They tend to remain in one area, not roaming freely like many other fishes.

The spotted handfish (Brachionichthys hirsutus) is somewhat more common, but even it is only found in a few locations nowadays. Early settlers around Hobart reported them being common, but now they have mostly vanished, and are now considered endangered. Only 20 years ago a book described them as ‘an excellent aquarium specimen’.¹ But now their numbers are so low that their location is not publicized, to guard against collection for illegal trade. Reasons given for their decline are loss of habitat, run-off from built-up areas, and particularly the introduction of the Pacific sea star, which eats their eggs.

The spotted handfish

Handfish are closely related to the better-known anglerfish. Anglerfish also have extended pectoral fins, but their best-known feature is their ‘lure’. Both anglerfish and handfish have a projection on their head, which in anglerfish serves to attract other fish. Smaller fish investigate what looks to them like a tasty morsel, only to find themselves swiftly becoming a meal for the anglerfish. However since handfish eat mostly worms and crustaceans, they do not appear to use their lure in quite the same way. Nevertheless the lure can be lowered or raised, so it may serve to attract prey too.

There is no suggestion that handfish are in any way a ‘missing link’ between fish and animals with legs. The handfish is undoubtedly a fish, with gills and fins, living at the bottom of the sea. So even though it can be said to ‘walk’, that does not mean that it is part-way along some evolutionary path to becoming a land creature. At the beginning God created all the living creatures to reproduce ‘after their kind.’ Handfish have always been handfish just as God said, and their offspring will always be handfish too.

We will do well to conserve this intriguing little creature, and try to keep it from extinction. It is one of the many treasures of God’s creation, over which He has made us stewards.

Pa kako mislis da od jedne vrste nastanu dve, razlicite, ako se medjusobno ukrstaju i stalno mesaju genetski materijal? 

 

Prvo za to uopste nije potrebna apsolutna izolacija, nego dovoljna da dve grupe drzi fizicki odvojene. A kao drugo i jos vaznije postoji vise vrsta tacnije nacina ili scenarija po kojima se vrsti razvrstanje. Ovo koje zahteva fizicku barijeru je alopatricki tip razvrstavanja medjutim postoje i drugi kao napreimer periopatricko koje uopste ne zahteva fizicku barijeru nego naprosto da jedna grupa sam fizicki ode na udaljeno mesto u potragu za novom vrstom hrane.

 

 

 

 

 

 Zato pitam odakle ti ideja za bilo kakvom apsolutno izolacijom kad em nije neophodna apsolutna izolacija a niti je izolacija fizickim preprekama jedini scenario.

sve jedno, vi bi ste oper mogli da argumentujete da su takvi stvoreni a da nismo rodjaci bez obzira sto delimo skoro  istu genetiku.

Nije svejedno zato sto ja ne kazem da nismo u rodbinskim vezama sa Homo erectusom

[Aquilius Cratus]

ne pitaj mene ja ne znam ni zbog cega bi trebalo od gustera da nastanu ptice meni je to totalna ludost... sto se mene tice nista to ne treba....

 

Tebe nisam ni pitao. Pitacu te ako tema bude o dogadjajima Paje Patka.

OK, rodjaci smo, ali da li je moguce da jednoga dana evoluiramo u dve razlicite vrste koje se nece moci ukrstati medjusobno? Mi i Pigmejci na primer?

Dve bliske vrste zapravo mogu da se ukrstaju, pretpostavlja se da se to desilo sa neardetalcima da su se ukrstili sa nama. http://news.nationalgeographic.com/news/2010/05/100506-science-neanderthals-humans-mated-interbred-dna-gene/

  Pa kako ces ti fizicki da odvojis ptice na priomer? Insekte? Ribe? Hajde objasni mi. I to da budo odvojeni milionima godina ptivce iz Srbije, recimo, i Rumunije. Pa da kod nas nastanu laste a kod njih rode.

Ne pricam ja o ukrstanju, jer ukrstanje je problem za evoluciju, ako ima ukjrstanja nema stvaranja razlicitih vrsta. Ukrstanje treba onemoguciti da bi nastale dve vrste, ali iskljuciti ga neki milion godina i to potpuno, apsolutno, i za svaku vrstu ponaosob.

 Sad ti kazem da fizicko odvajanje nije jedini nacin i da imas i drugi nacin a ti me ponovo to pitas. Razvrstavanje uopste ne zahteva milion godina vec, u zavisnosti od selktivnog pritiska i samog organizma, svega nekoliko generacija.

 

Zasto nisi pogledao ni jedan video od postavljenih?

Ja na ovu temu nemam sta da kazem osim da porucim svim evolucionistima da spreme po gajbu piva ako se budemo videli sa one strane

 Sto uopste nije fer plej posto ti ovde pises iskljucivo kada si sa one strane pa imas prednost i samo treba da sacekas.

Niko nije rekao da ukrstanja  nema. Desava se. Ukrstanjem zapravo i nastaju nove vrste, u jednoj vrsti se pojavi jedna osobina i ta osobina se ukrstanjem namnozni na potomke i tako "nastane" nova vrsta. 

 

Na nekoj manjoj skali, to ti je razlika izmedju rasa (boja koze), samo povecavaj skalu.

Ne znam. 

[SHADOWS OF THE LIGHT]

. Ne znam. 

 

Zasto onda trvdis da je druga vrsta?
