Help Wanted to ID these Sponges

[Kuksinhyd]

Hi Everyone, Please help me ID these sponges that i got in yesterday-

Thankx

sponge number 1
sponge number 2
and
sponge number 3

it is very, very difficult to correctly ID sponges.

*

First, the area of the sponge's origin must be known.
*

Second, the aquarist has to have access to, and know how to properly use, a microscope.
*

Finally, the aquarist has to have access to the technical literature describing the sponges by spicular type.
