THE Shanghai Ocean Aquarium plans to add three rare fish that have never been exhibited in the country before to its collection - the freshwater lionfish, sisorid catfish and sea apples.

The freshwater lionfish has a big brown head that accounts for one-third of its total length. It has spines on its skin that can cause pain if brushed against, but they pose no other threat, aquarium officials said.

The sisorid catfish is found in the mountain rivers of India, Myanmar and China and can grow to 12 centimeters in length. It has a flattened body with an adhesive organ on its stomach, which allows the fish to stick to rocks and maintain its position in turbulent water.

Sea apples are a kind of sea cucumber that is yellow, orange and purple. When sensing extreme danger, they produce toxic compounds, which can be released after death as well.

Sea apples can’t be that rare, a store around here had a tank full of ’em for not that much, maybe $5-$20, can’t remember the price.
