I took this video while at the #AquariaVattenmuseum
). A moment after recording this, I discovered the panel which explained what these #fish
were... These are #FourEyedFish
). The #aquarium
had the following information about them:
Despite the name, the four-eyed fish only have two eyes, but they are divided with a membrane that enables them to see both above and underneath the surface. The eyes are big and placed on top of the head. Each half of the eye is constructed differently to be able to take up light from the air in the water. This way, the fish has the advantage of both seeking prey and protection from predators both from above and underneath.
The four-eyed fish has internal fertilization and are live bearers. After completed fertilization, the female gives birth after about 2 months. At this point she may well be full with babies about the size of 3-5 cm and 10-15 in number.
The four-eyed fish inhabits the waters in and around coastal areas such as #mangroves
. They are able to live in both fresh and brackish waters. There are three known species in the genus of Anableps fish, all from the #Trinidad
area and northern parts of #SouthAmerica
