Coastal Ponds and Pools. Kalaoko-Honokohau has easily accessible tide-pools rich in intertidal life, and an unusual assemblage of anchialine pools. The tide pools are shoreline pools which have surface connections to the sea at high tides. They have diverse species mainly of marine origin. In contrast, anchialine (from the Greek meaning near the sea) pools are near shore pools without any surface connection to the sea, but have measurable salinity and show tidal rhythms. Anchialine pools have fewer but more distinctive animals. Crustaceans and mollusks are their most abundant and characteristic animals. Small red shrimp (opaeula) are the characteristic species.
