Calyx podatypa is a species of sea sponge belonging to the family Phloeodictyidae.

The species was first described in 1934 by American spongiologist Max Walker de Laubenfels.

[1] It is commonly found in shallow reefs, among seagrass and on mangrove roots.

It is described as being mostly hollow with growths that range from branched to lobate in shape and tubular projections.

[2] A number of biologically active compounds have been isolated from Calyx podatypa including Diketopiperazines and N-methylpyridinium salts with antimicrobial effects.
