Cave clams are relatives of sea clams that live in caverns and cliffs and dungeons and sewers. They like to hide in cracks and crevices, 
strongly resemble stone or rock with a hard to see crack. Some are more colourful, some dig under floors or drop from above. Clams in hiding ambush on 1-4. Sometimes tiny ones cover floors looking like flagstones or rough boulder covered floors in a cave. The biggest one's mouths are like great doors that can swallow you up. Some especially under the lairs of evil alchemists. 1in4 have a pearl worth 100gp per HD. Larger ones are more mobile and several might accidentally cooperate. Some underland and underwater races cultivate them.

d10 Cave Clam Adventures

1 The marsh fishermen started losing their dogs then children, now a legless survivor says it was damned giant clams!
2 Something crawls out of the well each night leaving a wet trail and making clacking sounds and anyone who goes to look is found decapitated
3 A child fell into a cave through a hole. An adult size entry by the old alchemist's ruined heap will let you get in to save the child. Locals all fear the dreaded clams and give up hope
4 A wet damp sinkhole by the sea was said to be where a pirate buried his treasure. A ship was sailed into a cave and sealed in. Adventurers may climb down the hole with ropes and help. Cave clams are in the lower parts of the hole before it opens into flooded cave of saltwater home of the great clam behemoth. Treasure is inside the clam and the sea entry was blown up by the pirate sealing his loot here
5 A small village popular with city visitors has had a clam outbreak as part of a curse. Fish folk hid an evil idol in a cave under the beach that is flooded and guarded by dread clams
6 A sea wizard made a dungeon only breathable for a few hours a day on the reef and marine cave clams infest it guarding an imprisoned sea nymph in a cave of pearls
7 A ship has been trapped by several enormous clams and the crew need help to fight the monsters and save the ship
8 A mermaid princess was eaten by a cave clam in a trench and her family seed someone to quickly rescue the body so she can be raised from the dead and still look pretty
9 A wizard has orcs and siege clams and has been attacking fortified buildings outside town
10 Migrating ram clams come ashore for ancient migration route, knock over everything in path and locals want help getting rid of them. Lots of poles slow or stop them best
11 A tribe of kobolds have been cultivating cams in the deep for aeons now have spares and they have been leaving pits with clams in the for idiots to fall in
12 Villagers years ago stored emergency supplies in cave and a recent check up had revealed cave clams living off rats had got in and grown too big to get past doors. These were a climbing variety who drop from the ceiling onto victims

Look out for those invisible fire trench ram clams that regenerate

  1. I concour. Dungeons also need cave corals which mysteriously grow to block passage into parts of the dungeon that need to be restocked or finished.
