## Bryaninops amplus
### Taxonomy and Nomenclature
*Bryaninops amplus* was first described in 2001 by ichthyologists Larson and Hoese. It belongs to the genus *Bryaninops*, which comprises a group of small, cryptic gobies often associated with coral habitats. The genus name *Bryaninops* is derived from Greek, meaning „moss-like appearance,” referring to their small size and camouflaged nature. The species epithet *amplus* means „large” or „ample,” which may relate to certain morphological features distinguishing it from closely related species.
### Description
*Bryaninops amplus* is a diminutive fish, typically measuring up to 3 centimeters in length. It exhibits a slender, elongated body with a translucent to pale coloration that aids in camouflage among coral branches. The species is characterized by a series of faint, irregular markings along its body, which can vary in intensity. Its fins are generally transparent, with subtle pigmentation on the dorsal and caudal fins. The eyes are relatively large, an adaptation that may assist in detecting predators and prey within the complex reef environment.
### Distribution and Habitat
This species is native to the Indo-Pacific region, with confirmed occurrences in areas such as the Great Barrier Reef, the Philippines, Indonesia, and parts of Micronesia. *Bryaninops amplus* inhabits shallow coral reefs, typically at depths ranging from 1 to 20 meters. It is often found residing on or near branching corals, particularly species of *Acropora*, where it uses the coral structure for shelter and protection from predators.
### Behavior and Ecology
*Bryaninops amplus* is a benthic, reef-associated fish that exhibits cryptic behavior, often remaining motionless or moving slowly to avoid detection. It feeds primarily on small planktonic organisms and tiny invertebrates, capturing prey with quick darting movements. The species is known to form loose associations with coral colonies, relying on the coral for both habitat and food resources.
Reproductive behavior in *Bryaninops amplus* is not extensively documented, but like other gobies, it is presumed to engage in demersal spawning, where eggs are laid on the substrate or coral surfaces and guarded by one or both parents until hatching.
### Conservation Status
As of the latest assessments, *Bryaninops amplus* has not been evaluated by the International Union for Conservation of Nature (IUCN). However, its reliance on coral reef habitats makes it potentially vulnerable to threats such as coral bleaching, habitat degradation, and climate change. Conservation of coral reef ecosystems is essential for the continued survival of this and many other reef-dependent species.
### Importance to Humans
Due to its small size and cryptic nature, *Bryaninops amplus* has limited direct economic importance. It is occasionally observed by divers and marine enthusiasts interested in reef biodiversity. The species contributes to the overall health and complexity of coral reef ecosystems, playing a role in the intricate food webs that sustain reef communities.
### Research and Study
Research on *Bryaninops amplus* remains relatively limited, with most information derived from taxonomic descriptions and general surveys of reef fish communities. Further studies on its ecology, reproductive biology, and population dynamics would enhance understanding of its role within coral reef ecosystems and inform conservation efforts.
