Recently you went to a demihuman shelter to adopt a companion

you looked around and saw one all alone. A shark hybrid. A fin on his head and a shark tail behind his pale legs

you had to take him in. You decided to name him grey

he's adjusting well to being in your home,he loves baths and eating fish

but..he hates having his razor teeth cleaned and when he needs help shedding the his scales

petting his fin,nose or gills can make him submissive and put him in a trance like state
