Betta smaragdina 'Guitar' is a naturally occurring variety or even subspecies that lives only in the Bueng Khong Long, Bueng Kan province in northeast Thailand (Isan). What makes them differ from the normal B. smaragdina are their guitar like markings on the dorsal and caudal fin.
The mouthbrooding species are sometimes called "pseudo bettas", and are sometimes speculated to have evolved from the nest-builders in an adaptation to their fast-moving stream habitats. [ 3 ] A phylogenetic study published in 2004 concluded tentatively that bubble-nesting was the ancestral condition in Betta , and that mouthbrooding has ...
Male and female individuals of Betta imbellis can live together outside of breeding season, as well as getting together for breeding. Males will build a bubble nest before breeding. After mating, the male catches the falling eggs and places them in his bubble nest. In 1–2 days, the eggs hatch and continue to absorb their yolk sack for 2 days.
Fish can sense sound through their lateral lines and their otoliths (ears). Some fishes, such as some species of carp and herring, hear through their swim bladders. [9] Hearing is well-developed in carp, which have the Weberian organ, three specialized vertebral processes that transfer vibrations in the swim bladder to the inner ear.
Betta fish can exhibit unusual sleep behaviors, often resulting in new betta owners assuming that their betta fish has died. In an aquarium, betta fish sleep anywhere in the tank they feel comfortable, including at the bottom on the substrate, floating at the mid-level, or at the surface.
A tubular worm snail has been newly discovered in the Florida Reef. The bright yellow snail is named after “Margaritaville,” a song by the late Jimmy Buffett. Newly discovered snail in Florida ...
Bettas are known as anabantids because they have a special lung-like labyrinthine organ in its head which enables them to obtain oxygen direct from the air. For this reason, they can live in water with very little dissolved oxygen, and can survive out of water for a short time as long as they remain damp. They are also efficient jumpers. [4]
Haliotis asinina, common name the ass's-ear abalone, is a fairly large species of sea snail, a tropical gastropod mollusk in the family Haliotidae, the abalone, also known as ormers or pāua. Both the common name and the scientific name are based on the shape of the shell, which is long, narrow and curved, resembling the shape of a donkey's ear.
