Cryptobiology 

 Remnant of a strange creature that once lived where sea and river meet

This figure of an aquatic creature apparently swimming, was discovered in an estuary. Old folks claim the creature once lived where sea and river meet, a unique habitat of many strange creatures, animals and plants as well. Mural background adds to the queer ambiance of the figure.

*Cryptobiology is the term used for the study of (i.e. search for evidence of the existence of) species that conventional biology does not generally accept the existence of, such as yeti, Bigfoot, the Loch Ness monster, chupacabra, etc.
