1 is a groyne which absorbs some wave power and catches sediment. another is a sea wall which deflects wave force and pushes it out to sea. i dunno any others I'm trying to find that out my self at the moment! lol
there are many types of sea defenses here are all i know:
groynes,
re sanding
seawalls
beakwaters
revelment
gabions

I understand if you do not believe me, all of these words sound strange, but it is the truth and nothing but the truth.
Barriers put in place to help stop or slow down coastal erosion from the waves.

Bridlington's defences consist of groynes on the beach, which lessen the effects of longshore drift.
natural forces wind, gales storms and waves wear away natural defenses such as slopes and grounds
there has been a sea wall built out to sea, but this has increased erosion ferther down the coast.
Coastal batteries positioned around San Francisco Bay and others.
sure I'm not going to answer that completely but i think yes and no yes cause they sound important no cause i don't know what they are.
the German fortifications were of concret construction many, many feet thick......

Coastal erosion can definitely effect tourism, because if the beach is not protected then people would not go there because they would not be safe. The prevention of coastal erosion can also affect tourism, because if the beach is protected from coastal erosion using sea defense, tourist will now come as it is safe. However these sea defenses can put off tourist as they might not be aesthetically pleasing, therefore it can also decrease the amount of tourists.
the defenses of a bat is BEES AND FLYS.
A sponge's defenses are spikes in the sponges body.
