Parambassis altipinnis

Unknown

Overview

Parambassis altipinnis is a freshwater fish species belonging to the glass perch family Ambassidae. This small, translucent fish is endemic to specific river systems in Southeast Asia, where it inhabits shallow, slow-moving waters with dense aquatic vegetation. The species exhibits the characteristic transparent body typical of glass perches, allowing internal structures to be visible through the skin.

Like other members of its genus, P. altipinnis likely feeds on small invertebrates and zooplankton in its natural habitat. The species faces severe conservation challenges that have led to its classification as Critically Endangered by the IUCN.

Primary threats include habitat degradation from agricultural runoff, urban development, and water pollution affecting the delicate freshwater ecosystems it depends upon. Dam construction and water extraction for irrigation have altered natural flow patterns in many river systems, further compromising suitable habitat. The species' limited geographic range makes it particularly vulnerable to localized environmental changes.

Additionally, collection for the aquarium trade may pose additional pressure on wild populations. Current population trends remain unknown due to limited monitoring and research efforts. Conservation initiatives are hampered by insufficient data on population size, distribution, and specific ecological requirements.

Effective protection will require habitat preservation, water quality management, and comprehensive surveys to better understand the species' current status and conservation needs.

Parambassis altipinnis faces severe threats from habitat degradation caused by agricultural runoff, urban development, and water pollution in its freshwater river systems. Dam construction and water extraction have altered natural flow patterns, while collection for the aquarium trade may add additional pressure on wild populations.

Frequently asked questions

Why is Parambassis altipinnis classified as Critically Endangered?
Parambassis altipinnis is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Parambassis altipinnis faces severe threats from habitat degradation caused by agricultural runoff, urban development, and water pollution in its freshwater river systems. Dam construction and water extraction have altered natural flow patterns, while collection for the aquarium trade may add additional pressure on wild populations.
Where does Parambassis altipinnis live?
Parambassis altipinnis occurs in Indonesia, and Papua New Guinea. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Parambassis altipinnis?
The main threats to Parambassis altipinnis are 5.3, and 8.1. The full IUCN-classified threat record for this species is detailed on the species page.
