The whale shark, Rhincodon typus, is a
slow moving filter feeding shark that is the largest living fish
species. It can grow up to 12.2 m (40 ft) in length and can weigh up to
13.6 tonnes (15 short tons). The shark is found in tropical and warm
oceans and lives in the open sea and can live for about 70 years. The
Boar Fish commenced to feed on frozen brine shrimp after being initially
encouraged with live daphnia. It seemed initially to feed better when
the circulatory water pump (powerhead) was turned. The Monterey Bay
Aquarium has come up with a guide to buying and eating fish from
sustainable sources. Almost three-forths of the world's surface is
covered in water. This water is home to over 20,000 different species of
fish. Every night, certain species of parrot fish envelope themselves
in a transparent cocoon made of mucous secreted from an organ on their
head. The earliest fossils of fish date back over 400 million years.
It's hard to decide which of the colorful parrot fish's many unique
characteristics is most remarkable.
