Abstract

Caridina sulawesi Cai and Ng, 2009, an endemic freshwater shrimp, has been described based on the type locality in Maros, South Sulawesi. Surprisingly, this species was reported from two rivers in Central Sulawesi. Here, we provided the data about ecological aspects and the recent distribution of the species on Sulawesi Island. The specimens were collected using a hand net in 2018 and 2019, from a small natural spring in Bobo and two creeks in Napu. Water temperature varied between 17 to 22°C. Our finding shows C. sulawesi inhabited almost all freshwater habitat exclude lake system, with high variation in elevation and water temperatures.

Highlights

The research on freshwater riverine endemic shrimp genus Caridina in Sulawesi was started about some centuries ago, intensive studies have begun in recent decades

Caridina sulawesi is an endemic shrimp inhabited in almost all freshwater habitat from a small natural spring to rivers, exclude lakes system

Summary

Introduction

Milne Edwards, is the most widespread freshwater shrimp from family Atyidae This genus contains more than 300 valid species and occurs from the Africa to Indo-Pacific region [1]. The members of this genus have at least two life strategies, i.e., prolonged type –required saline water for larval development, and abbreviated type –larval fully developed in freshwater [2]. The endemic shrimp genus Caridina from Sulawesi and small islands around comprise of 34 species. The research on freshwater riverine endemic shrimp genus Caridina in Sulawesi was started about some centuries ago, intensive studies have begun in recent decades. One of riverine endemic shrimp that has a unique distribution pattern in the island is Caridina sulawesi
