Pedder galaxias, Galaxias pedderensis, is a critically endangered Australian freshwater fish. Organisms with a conservation status of critically endangered have an extremely high risk of becoming extinct For a topic outline on this subject see List of basic Australia topics. It is considered to be extinct in the wild and was originally found only in Lake Pedder in Tasmania. Lake Pedder was a former natural Lake, located in the southwest of Tasmania, Australia, and is now the name used to refer to the much larger Tasmania is an Australian island and state of the same name It is located south of the eastern side of the Continent, being separated from it by Bass

Range

Originally recorded only in Lake Pedder and inflowing streams, after the construction of the Huon-Serpentine dam in 1972 (the "new" Lake Pedder), its range expanded initially into Lake Gordon and Wedge River. Lake Gordon is the name of a Lake created by the Gordon River Dam on the upper reaches of the Gordon River in south west Tasmania. However, by 1980 it had become very rare and no new specimens have been captured in the wild since 1996. Introduced trout are implicated as a major factor in the decline of this species.

Description

A small greenish-brown fish, off-white to silvery belly, a profuse irregular and highly variable pattern of alternating off-white and brownish contrasting bands extending into the base of the fins and breaking up into fine spots on the lowerr part of the sides. Length to 160 mm. The Millimetre ( American spelling: millimeter, symbol mm) is a unit of Length in the Metric system, equal to

Habitat

Before the construction of the new lake, this species preferred Lake Pedder itself which was quite shallow surrounded by white sandy beaches and small rooted aquatic vegetation as well as in swamps and low velocity waters with abundant instream organic debris and overhanging terrestrial vegetation.

Diet consists of small invertebrates, particularly arthropods and aquatic insect larvae, crustaceans and terretrial insects especially beetles, flies, cicadas etc. An invertebrate is an Animal lacking a Vertebral column. The group includes 98% of all animal Species — all animals except those in the Chordate Arthropods are Animals belonging to the Phylum Arthropoda (from Greek ἄρθρον arthron, " Joint " A larva ( Latin; plural larvae) is a juvenile form of Animal with indirect development, undergoing Metamorphosis (for example Structure of crustaceans As Arthropods crustaceans have a stiff Exoskeleton, which must be shed to allow the animal to grow ( Ecdysis or molting Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Beetles are the group of Insects with the largest number of known Species.

Conservation status

Critically endangered on IUCN Red List (last assessed in 1996). The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List) created in 1963 is the world's most comprehensive inventory of the global

Reproduction

Females are larger than males. Male genital papilla narrow, whereas female are broad and rounded, most noticeable during breeding season. 150 to 1,200 eggs averaging 1. 9 mm to 2. 3 mm in diameter when water hardened. Spawning reported to occur in spring (October) at water temperatures of 6. 7 to 7. 5°C. The Celsius Temperature scale was previously known as the centigrade scale.
