THE OCEAN SUNFISH: LARGEST BONY FISH

3 June 2013

Ocean sunfish. The ocean sunfish, also known as Mola mola, is the world’s largest bony fish. This strange creature is like no other. Come along and watch as a sunfish glides through the ocean waters.

Translated from Ecomare museum on Texel island in the Netherlands:

It looks as though it is going to be an ocean sunfish winter. Since the beginning of this year three of them have washed ashore on the Dutch beaches. The sunfish is certainly one of the strangest fish swimming sometimes in the North Sea. At beach post #23 on Texel last Wednesday a 60 centimeter long individual stranded. The day before, there was a 75 cm long one at Neeltje Jans in Zeeland, and on January 2, there was one near Castricum.

These were young animals; adult sunfish can be 4 meter in size.

Fossil haddock bones on Dutch beaches

Kemmerer, Wyoming boasts the site of the largest concentration of [Eocene] fossil fish.

On Dutch beaches, like of Texel island and the Zandmotor, many small fossil fish bones, cleithrum bones, were found. Recent research found out these bones belonged to Melanogrammus aeglefinus, the haddock, a species still living today.

The bones are about 100,000 years old, from the Eemien, the time before the last ice age. Last month, the research was published in Cranium journal.

In Belgium, cleithrum bones have been found of an older haddock species, now extinct, from the Pliocene age. That species is called Melanogrammus conjunctus.

American comb jellies on Dutch beach


This is a wart comb jelly video.

Translated from Ecomare museum on Texel island in the Netherlands:

A beach full of comb jellies – 08-01-15

Also in winter comb jellies wash ashore. Sometimes very many of them, like on December 23, when the beach at beach post #33 on Texel was filled with hundreds of wart comb jellies. …

Wart comb jellies are from America. Probably they come along in the ballast water of ships to Europe. Since 2006, they are found in the North Sea, Baltic Sea and Wadden Sea.

Ancient beaked whale fossil caught by fisherman

In the deep waters of the Bahamas, Wild Chronicles and Crittercam® gain a fleeting glimpse of a rare and most remarkable sea creature, the beaked whale. Incredibly, Crittercam® captures the first video of a birth among these rare whales. What you see will astound you.

A nice discovery! A piece of bone that Ecomare received in October turns out to be a piece of skull from a beaked whale. The bone was petrified, and therefore probably from the early Pleistocene, about 2 million years old. Ecomare received the bone from the Vonk family. The crew of their fishing vessel, the TX1, had this year netted it in the North Sea, near the English coast.

Fishing ships with TX are from Texel. Scientists cannot say which beaked whale species exactly this was.

Porpoise twins discovered for first time


This video, recorded at sea between Denmark and Sweden, is called Harbour Porpoise having fun at our boat.

Translated from Ecomare museum on Texel, and the Utrecht University veterinary department in the Netherlands:

Thursday, December 18th, 2014

For the first time biologists have found out that porpoises may also have twins. During an investigation of the cause of death of a stranded porpoise, researchers at Utrecht University discovered two female fetuses in the womb of this cetacean. The discovery of twins in a porpoise has not been previously described in literature. With other whales and dolphins this is not a common phenomenon either. So, a unique find!

Beached

The porpoise stranded on April 13, 2011 on the beach of Texel. It was a dead adult female of 151 centimeter and nearly 50 kilogram.
