Bivalves, such as clams and oysters, are primarily aquatic and lack adaptations for terrestrial life, such as lungs or specialized structures to retain moisture. Their bodies are designed for filter feeding in water, with gills for respiration. In contrast, gastropods, like snails and slugs, have developed adaptations like a lung-like structure for breathing air and a moist, slimy body to prevent desiccation, enabling them to thrive in terrestrial environments. These evolutionary differences highlight their distinct ecological niches.
What else can I help you with?
What do bivalves lack that other classes have?
other molluscs have a radula which is lost in the bivalves, they also have a reduced head and nervous system. most are also lamellibranchs (filter feeders) which is why they have lost the radula (used for rasping plant life by herbivores such as the gastropods).
What do bivalves do when a grain of sand gets in its shell?
When life gives bivalves sand, they make pearls.
Vertebrates that are adapted to life both on land and in the water are?
amphibians
How have plants and animals adapt to life on land?
Plants and animals have adapted to feed, reproduction, and life on land by utilizing oxygen or carbon dioxide that is absorbed through lungs or via photosynthesis rather than using gills. They have adapted with fur to keep them warm and legs to move them safely on land. Plants have adapted to utilize sunlight and animals to reproduce.
What environment are turtles adapted to?
Turtles are adapted to various aquatic and terrestrial environments depending on the species. Aquatic turtles, like sea turtles, are adapted for swimming and live in oceans, seas, and freshwater habitats. Terrestrial turtles, such as box turtles, are adapted to living on land and can be found in forests, grasslands, and deserts.
Were reptiles the first vertebrates to be well adapted to live their entire lives on land?
Mammals,birds and reptiles are fully adapted to life on land. Fish live in water and amphibians start their life in water, then live on land.
Reptiles are much more extensively adapted to life on land than amphibians in that reptiles?
lay shelled eggs
Where do most?
Most live in the ocean, or along the shore. Some crustaceans, such as wood lice, have adapted to life on land.
How is the digestive tract anatomy adapted to life on land?
The digestive tract is forced to adapt to life on land due impart to the eating habits of the living creatures and their given surroundings as well as the food that is being consumed on the land itself.
Where do most crustaceans?
Most live in the ocean, or along the shore. Some crustaceans, such as wood lice, have adapted to life on land.
Where do most crustaceans live?
Most live in the ocean, or along the shore. Some crustaceans, such as wood lice, have adapted to life on land.
How have animals adapted to life on land?
Animals grew legs to help them walk on land. They also developed lungs to enable them to breathe. Many grew hair to keep their body temperatures regulated and their senses were adapted to be able to do things like find food and avoid predators.
