Along with other vital organs such as their ventral nerve cord, stomach, heart, etc., important organs are inside their heads due to the safety this part of the body provides over the tail end.
If you’ve ever prepared head-on shrimp, then you’ll know that the head and thorax are the thickest and hardest parts of the body.
This section, known as the cephalic portion, is covered with a thick protective substance, known as an exoskeleton.
This exoskeleton guards the shrimp’s internal organs against harm, as damage to any of them could be fatal.
Shrimp have evolved this way over time to help guarantee their survival.
