INTERAMBULACRUMS Meaning and
Definition
-
Interambulacrums refer to the areas on the aboral or upper surface of a sea urchin's test or shell. Specifically, they are the interradial areas where the ambulacra, which are the linear areas containing specialized tube feet used for locomotion and feeding, are absent. These interambulacrums form a distinctive geometric pattern on the surface of the test.
In sea urchins, the body is enclosed within a hard, calcareous shell composed of five ambulacra and five interambulacrums. The ambulacra run from the animal's mouth to the base of the spines, forming radial patterns on the oral or bottom surface. On the other hand, the interambulacrums are the triangular or quadrangular spaces that lie between the ambulacra, creating distinctive patterns on the aboral surface.
The interambulacrums are typically smoother and flat compared to the raised, articulated ambulacra. They lack tube feet, as their presence is limited to the ambulacra. The size and shape of the interambulacrums can vary between different species of sea urchins, contributing to their overall shell morphology.
Overall, interambulacrums are an important part of the external anatomy of sea urchins. Their arrangement and characteristics play a role in classifying and identifying different species, while also contributing to the overall functionality of the sea urchin's locomotion and feeding strategies.
