Gobies

From record breakers to species with very unusual habits, gobies are among the most widespread and varied of all fish. Gobies also include some critically endangered species.

The male of the freshwater diminutive person dwarf goby is simply 0.4 creeps extended. A marine goby, known as Trimmatom nanus, is even smaller at 0.39 inches, while several others are only slightly larger. It is only since the early 2000s that the goby world record for the smallest vertebrate (animal with a backbone) on the planet has been beaten—by another fish, a relative of the carp known as Paedocypris, that only reaches a length of 0.3 inches.Not all gobies are tiny, though. Some, such as the violet goby, are relatively large and can grow to more than 22 inches in length. 

Varied Family

There are a considerable number of contrasting species in the house, and gobies are astoundingly fluctuated in their inclinations. For example, mudskippers do as their name suggests. They skip over the mud at low tide in the mangroves where they live. They come out of the water to feed and display to each other on the exposed mudflats.

Other gobies share burrows with a species of shrimp. The burrow is dug out by the shrimp, which benefits from the association because the goby raises the alarm when any predator approaches. The gobies, for their part, get security resulting from the fact that they are fit to plunge intothe tunnels at the first indication of peril. The sponge goby also dives for cover when threatened; right intothe body cavity of a loggerhead sponge. There are even some gobies that climb waterfalls.
