2. FISH WITHOUT WATER???
A fish is any member of a paraphyletic group of organisms that consist of
all gill-bearing aquatic craniate animals that lack limbs with digits.
Anabas testudineus
It sounds like something out of a sci-fi movie, but
it's 100% true: Australian officials are closely
monitoring the climbing perch (Anabas
testudineus), a frighteningly resilient and
aggressively invasive fish that can live out of
water for six days as it crawls across dry land.
the fish can also survive in the mud of a dried-up
creek bed for half a year
3. LUNG FISH
Lungfish (also known as salamanderfish) are
freshwater fish belonging to the subclass Dipnoi.
Lungfish are best known for retaining
characteristics primitive within the Osteichthyes,
including the ability to breathe air, and structures
primitive within Sarcopterygii, including the
presence of lobed fins with a well-developed
internal skeleton
The modern lungfishes have a number of larval features, which
suggest paedomorphosis. They also demonstrate the
largest genome among the vertebrates
4. mangrove killifish
it spends several months of every year out of the water
and living inside trees Hidden away inside rotten
branches and trunks, the remarkable creatures
temporarily alter their biological makeup so they can
breathe air.
Biologists studying the killifish say they astonished it
can cope for so long out of its natural habitat
The discovery, along with its ability to breed
without a mate, must make the
mangrove killifish, Rivulus marmoratus Poey, one
of the oddest fish known to man
