☆ Echinodermata - radially symmetrical marine invertebrates including e.g. starfish and sea urchins and sea cucumbers.
☆ Crustacean Endocrinology
Eyestalk in crustaceans is a reserve for many hormones reg-
ulates several physiological functions comprising growth and
reproduction. An array of hormones released from crustacean
eyestalk includes crustacean hyperglycemic hormone (CHH),
molt-inhibiting hormone (MIH), mandibular organ-inhibiting
hormone (MOIH) and gonad/vitellogenesis-inhibiting hormone
(VIH) besides other hormones and neurotransmitters . These eyestalk neuropeptides are collectively
called as CHH-family peptides since they share the functional
similarity and show multiple biological functions .

Explanation:
Echinoderms : (i) they have radially symmetrical body with varying shapes.
(ii) they have exoskeletons with spines all over it.
crustaceans: (i) their head and thorax are fused.
(ii) they have two pairs of antennae ( feelers ) extending from the head.
