Is ICMP fragmented?

Question

Ping

I am going through an online training course in which it is proposed to ping a google dns address with a packet size of 1400 bytes.
ping -l 1400 8.8.8.8 Packet
exchange from 8.8.8.8 to 1400 bytes of data:
Reply from 8.8.8.8: number of bytes=68 (sending 1400) time=13ms TTL=116
Reply from 8.8.8.8: number of bytes=68 ( send 1400) time=13ms TTL=116
Response from 8.8.8.8: number of bytes=68 (send 1400) time=15ms TTL=116
Response from 8.8.8.8: number of bytes=68 (send 1400) time=13ms TTL=116
Not I can understand, judging by the output, 68 bytes are sent, what does sending 1400 in brackets mean?
Why only 68 bytes?

Answer 1

The answer is 68 bytes. Sending - 1400 bytes.

Answer 2

Any IP packet can be fragmented .

Answer 3

The packet is fragmented, not the protocol.
