Annelids have (a):
pseudocoelom.
true coelom.
no coelom.
none of the above

true coelom.

Explanation:

The Annelida Phylum gathers the animals with cylindrical and segmented body structure, with evident outer rings, also internally subdivided (true metamerization).

These bilateral symmetry invertebrates have three embryonic (triblastic) leaflets, and a general organism cavity called a coelom. In the outer surface of some species, in the epidermal cuticle, there are small hairs (bristles) that support during locomotion, and the amount of these filaments is a criterion used in the differentiation of organisms.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
