Rays of sunshine

As the sun broke through we walked down the beach to see what we could find. The sea was retreating and making the sand into a wide firm walkway. As we ambled our way along our eyes were drawn down. It’s impossible isn’t it? to walk along a beach without beachcombing is like having a fruit pastel and not chewing.

As we continued to walk it became apparent the high tide had left spoils. There had obviously been a hatching of Thrornback Rays (among others) as their egg cases littered the tideline. This is a fish that has shown philopatric behaviour; that is the returning of a migrating fish to a particular area to feed or breed. The Shark Trust (Rays are closely related to Sharks) run an interesting website with an Egg case id guide. http://www.sharktrust.org/en/great_eggcase_hunt/
