I’ve always wondered how many fish are actually in the sea. “There’s plenty of fish in the sea” is an old saying that everyone has heard. But how many are there really?
New species are found everyday in the ocean. Here is a list of the many species already found: Blue Tang Surgeonfish, Sturgeon Poacher, Butterfly goodeid, Percula Clownfish, Four-Eyed Fish, Guadalupe Cardinalfish, Bala Shark, Topminnow, and many more. Because earth has more oceans then land it’s no surprise that there are so many types of fish. Many of the fish in the sea have adapted from other species. The fish adapt to live easier in their environment; for instance if a fish needs to live in a darker place it might have adapted to lose its eyesight because it’s not needed. This occurs often in the ocean, and it relates back to Darwin’s law of evolution.
In studies today 230,000 species have been found. Recently a 10 year study was released and the topic of study was just how many fish are in the sea. About 360 scientists got together to survey different regions of the world. Even though new species are always being discover they have come to an estimate for 230000 species.
In the ocean, fish have to adapt to several problems including, regulating salt intake, obtaining oxygen, adapting to water pressure, dealing with wind, waves and changing temperatures, and getting enough light. In that you can see all the different ways why a fish might change and become new species. One fish in fact called the Deep Sea Dragon fish, or Grammatostomias Flagellibarba (by scientist) lives in the darker part of the ocean and to attract fish it lights up a lure connected to his belly.
My favorite is the Sunburst Anthias. This fish can be found in the Western Pacific. Other names for it are the Fathead Anthias and Hawk Anthias. There is a reason this little fish is called the Sunburst Anthias. The colors of it are bright and loud. It is almost like you are actually looking at the sunset. Some of those colors include bright orange and fierce fuchsia.
All in all it seems likea new species of fish will be revealed every year. Small fish, large fish, spiky fish, and even fish that light up. The amount of space in the ocean is almost endless and with all the room to grow new fish are moving to new places and adapting into new species.
