Crayfish can be found in various habitats, including streams, rivers, and lakes. They are important in Florida’s ecosystems as they help to control algae and other organic matter. Some species of crayfish that can be found in Florida include the red swamp crayfish and the Everglades crayfish.

Barnacles

Barnacles are unique crustaceans that are typically found in marine environments, such as the rocky intertidal zone. They have a hard, calcified shell that attaches to rocks, piers, and other submerged surfaces. Barnacles are filter feeders, meaning they rely on water currents to bring them food. They possess feathery appendages called cirri, which they use to capture plankton and other small organisms. Barnacles are not commonly harvested for food in Florida, but they play an important role in the marine ecosystem by providing attachment surfaces for other organisms to settle on.

Mollusks

Bivalves

Bivalves are a group of mollusks that have a two-part hinged shell. They are found in both freshwater and marine environments and are highly valued for their meat. Some well-known bivalves include clams, oysters, and mussels. These mollusks are filter feeders, using their gills to extract food particles from the water. Florida is home to various species of bivalves, including the Eastern oyster, hard clam, and bay scallop. Bivalves are not only an important food source but also play a vital role in filtering water and maintaining water quality.

Gastropods

Gastropods are a diverse group of mollusks that includes snails, slugs, and sea snails. They have a single, coiled shell or no shell at all. Gastropods can be found in both terrestrial and aquatic environments, with some species living in marine, freshwater, or even brackish habitats. In Florida, there are numerous species of gastropods, ranging from land snails that inhabit forests and gardens to marine snails that inhabit the state’s coastal waters. Some gastropods, like the lightning whelk and the horse conch, are highly sought after by collectors.

Cephalopods

Cephalopods are a group of highly intelligent mollusks that includes octopuses, squids, and cuttlefish. These creatures are known for their remarkable ability to change color and camouflage themselves in their surroundings. Cephalopods have a soft body and possess tentacles or arms, which they use for capturing prey. In Florida’s waters, the common octopus and the Atlantic brief squid can be found. Cephalopods are not as commonly consumed as other mollusks but are fascinating creatures to observe in their natural habitats.

Worms

Flatworms

Flatworms, also known as planarians, are a type of worm that have a soft, flat body. They can be found in both freshwater and marine environments. Flatworms are known for their regenerative abilities, as they can regrow lost body parts. In Florida, some species of flatworms are considered invasive and can have a detrimental impact on native species and ecosystems. These worms feed on various organisms, including small crustaceans and other invertebrates.

Segmented Worms

Segmented worms, also known as annelids, are a diverse group that includes earthworms, leeches, and marine worms. They have a distinct body composed of repeating segments. Segmented worms can be found in a wide range of habitats, from soil and freshwater to marine environments. In Florida’s waters, various species of marine worms, such as the Christmas tree worms and the feather duster worms, can be observed. These worms play important roles in nutrient cycling and sediment stabilization.

Jellyfish and Sea Anemones

Jellyfish and sea anemones belong to the phylum Cnidaria and are characterized by their stinging cells called nematocysts. Jellyfish are gelatinous, free-swimming creatures that can be found in both saltwater and freshwater environments. Sea anemones, on the other hand, are sessile organisms that attach themselves to rocks or other substrates. They have a cylindrical body with numerous tentacles surrounding their mouth. In Florida’s waters, various species of jellyfish and sea anemones can be encountered. While some species can deliver a painful sting to humans, others are harmless and add beauty to the underwater world.

Sponges

Sponges are aquatic invertebrates that belong to the phylum Porifera. They are filter feeders, drawing water through their porous bodies to extract nutrients. Sponges can be found in both freshwater and marine environments, and they come in a wide range of shapes, sizes, and colors. In Florida, the well-known barrel sponge and the encrusting sponge are common species encountered. Sponges are important in ecosystems as they provide shelter for small organisms and help to filter water, resulting in increased water clarity.

Corals

Corals are marine invertebrates that form vast underwater ecosystems known as coral reefs. They consist of colonies of tiny, polyp-like animals that secrete a calcium carbonate skeleton. Coral reefs are incredibly diverse and are considered one of the most biologically productive ecosystems on Earth. In Florida, the Florida Reef is the only barrier coral reef in the continental United States. It is home to numerous species of corals, including brain corals, staghorn corals, and elkhorn corals. Coral reefs are not only visually stunning but also provide crucial habitats for a wide variety of marine organisms.

Sea Urchins and Sand Dollars

Sea urchins and sand dollars are echinoderms, a group of marine invertebrates characterized by their spiny skin and pentaradial symmetry. Sea urchins typically have a spherical or disc-shaped body covered in sharp spines, while sand dollars have a flat, round body covered in fine spines. Both sea urchins and sand dollars play important roles in marine ecosystems.
