Una vez pasando los 1,000m el agua está completamente desprovista de luz, se ha alcanzado el océano profundo.Īquí abajo, las temperaturas caen súbitamente a 3.9✬, y constantemente están cerca de la congelación. Por debajo de los 200m, donde entra todavía poca luz, comienza la zona crepuscular.

Gran parte de la vida marina que conocemos vive ahí, donde hay luz. Pero, ¿qué es exactamente el océano profundo? A los primeros 200m del océano se le llama mar abierto. El 95% del océano permanece inexplorado, la mayoría del mismo considerado como el océano profundo. Pero, ¿qué hay ahí abajo? ❼uánto sabemos de él? Realmente, no mucho. Un lugar tan diferente, lleno de extrañas formas de vida. We now know that despite this lack of light, many creatures can live in this extreme place, such as: microorganisms in hydrothermal vents, deep sea corals, fish, and many other bizarre creatures.Įxploring the deep ocean is challenging because of the harsh conditions, but marine scientists are on a mission to document new species in this unusual place.Įl océano profundo. It was originally thought that life cannot survive without light. But how could anything thrive in these conditions? The pressures at these depths range from about 40 to over 110 times the pressure of Earth’s atmosphere. Once you pass 1,000 meters, the water is completely devoid of light, and you have reached the deep ocean.ĭown here, temperatures plummet to 39 degrees Fahrenheit, and constantly stay near freezing. Much of the marine life we know of lives here, where there is light.īelow 200 meters, where there is little light left, you enter the Twilight Zone. 95% of the ocean remains unexplored, most of which is considered the deep ocean.īut what exactly is the deep ocean? The first 200 meters of the ocean are the open ocean. But what’s down there? How much do we know about it? As it turns out, not very much. A place so different, filled with strange life forms. As always, make sure you research the species you want to introduce to your tank to ensure you get species specific feeding advice.The deep ocean. Some species are quite simple to feed, others are more difficult. If you’re an experienced fish keeper, looking for a unique and extremely interesting new inhabitant for your saltwater tank, the starfish might just be for you. Their main diet will be based on the food they usually eat in the wild, for some this will be meaty foods, for other this will be algae. Come in a huge range of bright colors.Īs we’ve mentioned, it’s important to feed your starfish based on the particular species. Although they can grow large, they are relatively easy to care for.

If it does need to be supplemented, place small clam meet or tablets underneath them. Linckia Starfish ( Linckia laevigata) When introduced to well-established aquarium, little needs to be done to supplement diet. Plain beige appearance but useful in sifting through sand. Will very quickly clear out detritus and left-over food and can starve if not supplemented. Sand Sifting Starfish ( Astropecten polycanthus) Needs to be directly fed a variety of foods on the sand bed, such as shrimp, urchins and mollusks. Highly active and enjoy complex environments. Supplement its diet with small pieces of shrimp, and flaked food.Īdvertisements One of the more common Fromiaspecies. Marble Sea Starfish/Tile Sea Star ( Fromia monilis) Include plenty of live rock as they forage for micro-organisms and detritus. They will eat soft corals, sponges, and tubeworms. Common Name Diet Details Chocolate Chip Starfish ( Protoreaster nodosus) Chopped clams, shrimp and squid. Here is a brief table detailing what each species of popular aquarium starfish eat. Some species such as Chocolate Chip eat corals others are not as destructive but still require a diet which a lot of hobbyists are unable to provide. It’s really important to thoroughly research the species before you add it to your tank. Whilst they as usually nocturnal, they will quickly adapt to daytime feeds after being exposed to them often enough. If you’re worried about your fish eating the food before the starfish, place the starfish directly on top of the food when you place it in the bottom of the tank.
