Hybridoma Technology ( Production , Purification , and Application )
Observing aquatic life and their body structures
1.
2. Observe and classify aquatic animals according to their
body structures and adaptation to their environment
3. 1. Fishes
It has a spindle shaped body.
The body is covered by scales.
Respiration is by gills.
On the head a pair of nostrils are present
internal nostril are absent.
On the head a pair of eyes is present.
4. - are branching organs located
on the side of fish heads that have
many, many small blood vessels
called . As the fish opens
its mouth, water runs over the gills,
and blood in the capillaries picks up
oxygen that's dissolved in the water.
Air bladder -
Fins – all fish have fins which are use
for swimming (locomotion), balance,
stability, and steering.
5. – is a simple animal
with many cells, but no mouth,
muscles, heart or brain. It is
sessile: it cannot move from
place to place the way most
animals can. A sponge is
an animal that grows in one spot
like most plants do.
6. - are radial
symmetry and tentacles
with stinging cells. Hydra
and other cnidarians are
radially symmetrical—able
to asexually divide into
identical pie-shaped
segments, like a flower
pot. Cnidarians also
feature tentacles with
stinging cells. Ex: corals,
hydras, jellyfish,
Portuguese men-of-war,
sea anemones, sea pens,
sea whips, and sea fans. Sea anemones
corals
Sea whip
7. - also
spelled mollusc, any
soft-bodied
invertebrate of the
phylum Mollusca,
usually wholly or
partly enclosed in a
calcium carbonate
shell secreted by a
soft mantle covering
the body. They feed
and breathe through
their gills.
8. They have a star-like appearance and are spherical or
elongated.
They are exclusively marine animals.
The organisms are spiny-skinned.
They exhibit organ system level of organization. ...
They are triploblastic and have a coelomic cavity.
The skeleton is made up of calcium carbonate.
10. Among them are webbed feet, sharp claws, whiskers,
sharp teeth, large beaks, wings, and hooves. In most
aquatic animals, swimming is a must. To aid swimming,
many animals have adapted and evolved with webbed
feet.
11. Other common adaptations seen in wetlands
animals are webbed feet, a second clear eyelid that
can act like goggles when swimming underwater,
and camouflage coloring of fur or skin.
12. > Frogs that spend more
time in water have long,
very strong legs. They use
these legs for jumping and
swimming long distances,
mostly to escape from
predators or catch prey.
Some frogs also have
webbed feet, which is just
skin between their toes.
This also helps them swim
faster and longer.
