The Canvey Island Monster and what it implicates for the Montauk monster

In November 1954, The Canvey Island Monster was the name given to creature whose carcass washed up Canvey Island, Essex ,UK A second, more intact, carcass was found in 1955. It recalls the Montauk monster in modern times.

The 1954 creature was described as being 2.feet 3 inches (68 cms) long with reddish brown skin and bulging eyes and gills. It appeared to have hind legs with five-toed horseshoe-shaped feet but no forelimbs. Its remains were cremated after an inspection by zoologists who said that it posed no danger to the public. Nearly 3 months later Reverend Joseph Overs found another carcass of the creatures about 2 miles from the first creature's discovery This creature was larger and the carcass in better condition. Described as about 4 feet ( 120cms) long and an estimated weight of 25 pounds. It had the same large eyes, nostrils, sharp teeth, and gills with the same legs and feet as the first creature.

In 1999 journalist Nicholas Warren looked into the 1954-55 findings. He was unable to locate any official records at the Plymouth Marine Biology Association Laboratory or the National Rivers Authority about the creature being identified or listed as unknown. . He found that there were accounts from some locals who believed the creature was an anglerfish. Later he received a letter from Alwyne Wheeler, formerly an ichthyologist at the Department of Zoology at the Natural History Museum, informing him that in his opinion the specimens were anglerfish, and that their fleshy pectoral fins are often mistaken by lay observers for short legs with feet. There was a 68lb specimen caught on the shore of Canvey Island in 1967 .However, others have speculated that the creature may have been an Ogcocephalidae or Batfish .This species of fish already possess leg-like fins and also have reddish coloured skin.

If this was a mis-identification then what does that say about the modern day Montauk monster? Is it also a mis-identification of a known species?
