Some gastropods, for example the freshwater apple snails (family Ampullariidae) [7] and marine species of genus Strombus [8] can completely regenerate their eyes. The gastropods in both of these families have lens eyes. Morphological sequence of different types of multicellular eyes exemplified by gastropod eyes: [9]
A betta fish's lifespan can be impacted by the care it receives, WebMD reports. Bettas may live longer if their tank is clean, the environment is calm and their diet is healthy.
Sinum perspectivum, common name the white baby ear, is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae, the moon snails. [1]
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 ...
There is evidence that the genetic basis for aggression in betta fish is not exclusively sex-linked – a 2019 study found that female bettas of the fighting strain show significantly higher levels of aggression than their female wild-type counterparts, despite the fact that historically only male bettas have been used in fights and thus ...
Male individuals of Betta smaragdina will build a bubble nest before breeding. The temperature at which breeding typically occurs is 25.6 to 26.7 °C (78.1 to 80.1 °F). Males and females can live together and the male and female should already live together for breedi
However, they are also known to eat algae, seagrass, and other small creatures, such as sea slugs or sea snails. The sponges that make up a large percentage of their diet are actually subject to scientific study. As the sea bunny feeds on highly toxic sea sponges, they steal these toxins and utilize them as a defense mechanism.
