Brissus latecarinatus is a species of sea urchins of the family Brissidae.

[3] It has a crescent shaped mouth and a large anal opening underneath.

[2] Eggs are retained on the peristome, near the periproct, or deep inside the concavities on the petaloids during the typical practice of brooding.

[2] Embryos grow into planktotrophic larvae (echinoplateus), which descend to the bottom and use their tube feet to cling to the earth where they eventually transform into juvenile urchins.

[5] buries itself in the sand, processing it to get rid of debris and other clinging materials.
