The touch tank
Mandkind and Shores – area 17 : The touch tank
The pollack, which lives close to rocks and slopes, likes to spend time in shipwrecks looking for its lunch. This hunter can lay up to 4 million eggs. Once hatched, the young stay close to coasts. They move away from them when they are strong enough.
This fish lives in cold waters around the world, weighs about 2-3 kg and reaches a length of 50-90 cm on average, though these figures vary greatly from one individual to the next. The largest individuals can lay up to 15 million eggs at once, which float on the surface of the water, within reach of predators. This is why most eggs are eaten quickly.
Between the 16th and 20th centuries, cod was central to America’s economy as it was so plentiful. A carving of a cod was even put up in the Massachusetts House of Representatives in Boston.
Recognisable by its ringed tail, the thornback ray is often less than 100 cm long. It spends its days partially buried and eats molluscs and crustaceans, which it takes by surprise from this position. It is especially appreciated in cuisine and is also known for its rectangular, flat eggs. It is also known as the “Mermaid’s Purse”.
