Sponges are
simple
,
asymmetric
,
sessile
animals
The sponge's
body
is built around a system of
water canals
Poriferan water flow:
Water enters through tiny holes called the
ostia
Water flows through
ostia
into the
spongocoel
Water exits through a large hole called the
osculum
Sponges lack
tissues
, groups of
specialized
cells
that perform a
specific
function
Skeletal structural elements that make up the framework of body of sponge
Spicules
3 sponge body types (in order of complexity):
Asconoid
No
invaginations
in body wall
Syconoid
Single
spongocoel
, many
invaginations
Leuconoid
Multiple
spongocoels
Sponge group that exhibits symmetry
Barrel
sponges
Collar
cells
or
choanocytes
are
flagellated cells
that circulate
water
and trap
food
Larval stage of most sponges
Amphiblastula
Sponge groups based on spicule composition:
Calcarea
-
Calcium
Carbonate
Other 3 groups -
Silica
4 sponge classes (CDHH):
Calcarea
Demospongiae
Hexactinellida
(Glass spicules)
Homoscleromorpha
Used in Japanese weddings as a gift to a couple
